TW201442397A - Hybrid induction motor with self aligning permanent magnet inner rotor - Google Patents

Abstract

A hybrid induction motor includes an inductive rotor and an independently rotating permanent magnet rotor. The inductive rotor is a squirrel cage type rotor for induction motor operation at startup. The permanent magnet rotor is axially displaced and variably coupled to the inductive rotor (or to a motor load) through a clutch and is allowed to rotate independently of the inductive rotor at startup. The independently rotating permanent magnet rotor quickly reaches synchronous RPM at startup. As the inductive rotor approaches or reaches synchronous RPM, the coupling between the inductive rotor and the permanent magnet rotor increases until the two rotors are coupled at the synchronous RPM and the motor transitions to efficient synchronous operation.

Description

Hybrid induction motor with automatic alignment permanent magnet rotor

This case is part of the continuation of US Patent Application on April 20, 2012, application No. 13/452,514, and is merged with Application No. 13/452,514.

Modern inventions relating to electric motors, particularly with respect to induction motors, have separate permanent magnet rotors that non-fixedly engage the inductive rotor to allow the motor to operate asynchronously after re-assembly at the beginning of the asynchronous operation.

The preferred form of electric motor is the AC induction brushless brushless motor. The rotor of the electric motor includes a casing (or a runner with a chinchilla in a squirrel cage) in which there is a rotating stator coil. The outer casing consists of an axially rotating rod angularly separating the surrounding rotor. The alternating current supplied to the stator coil introduces a rotating stator coil magnetic field into the rotor, and the rotatory magnetic domain directs current into the rotating rod. The induced current produces an induced magnetic field that interacts with the stator coil magnetic field to produce torque and rotor rotation.

When introducing current into the rotating rod, it is required that the rotating rod cannot synchronously move (or rotate) with the rotating stator coil magnetic field, because electromagnetic induction requires relative motion (also called transfer), which is a conductor between the magnetic field and the magnetic field. Therefore, the rotor must reduce the magnetic field about the stator coil to guide the current into the strip, then generate the torque, and then sense The motor is therefore called an asynchronous motor.

The disadvantage is that the low-power electromagnetic induction motor does not produce higher performance at the original design operating rate, and the power consumed by the stator coil remains the same under reduced load, resulting in lower efficiency.

One way to improve the performance of an electromagnetic induction motor is to add a permanent magnet to the rotor. Initially, a motor incorporating a permanent magnet will start operating in the same manner as a typical induction motor, but when the motor incorporating the permanent magnet reaches a certain operating rate, the magnetic field of the stator coil will be synchronized with the permanent magnet. However, permanent magnets are limited in size because if the permanent magnets are too large, the motor will not operate. The above-mentioned size limits make the advantages of permanent magnets limited.

The present invention addresses the above arguments and a need for a hybrid induction motor consisting of an inductive rotor and an independently operated permanent magnet rotor. When the induction motor starts, the induction rotor is a squirrel-cage motor rotor (for example, a motor shaft) that can be permanently combined with a load motor. With the clutch, the permanent magnet rotor and the inductive rotor are non-fixed combinations and can rotate independently and independently when the induction rotor is activated. The independently rotating permanent magnet rotor quickly reaches the synchronous RPM (rpm) at start-up. When the inductive rotor approaches or reaches a synchronous per minute speed, the coupling of the inductive rotor and the internal permanent magnet rotor increases until the two rotors combine and reach a synchronous speed per minute, and then the motor enters an efficient synchronous operation.

In one entity, one is provided by a separate slip clutch The discrete angular positions of the calibration between the permanent magnet rotor and the induction magnet rotor are combined and the internal permanent magnet rotor and the induction rotor are combined.

According to one aspect of the invention, it provides a hybrid induction motor comprising an external induction rotor and a freely rotatable permanent magnet rotor that can be rotated without being limited by the rotational flux of the stator coil. When the motor is powered, the permanent magnet rotor will immediately accelerate to keep up with the rotating stator coil magnetic field, and the external induction rotor and load will also reach a synchronous rate. When the external induction rotor approaches the rotational speed (the stator coil magnetic field and the rotational speed of the permanent magnet rotor), the lockup clutch engages, causing the external inductive rotor and the permanent magnet rotor to combine. The lock-up clutch is fixed above the motor's designed torque. As soon as it is overloaded, the clutch will loosen and begin to slide until the load returns to the synchronous rate. The clutch lock is designed to skip the operating slip at a particular frequency and engage the operating frequency.

The present invention provides a hybrid induction motor having a permanent magnet rotor connectable to a rotor field. When the external induction rotor overcomes the friction generated by the slip clutch at start-up and the inertia of the permanent magnet rotor itself, the permanent magnet rotor can reach a synchronous speed (the clutch torque is to achieve the best motor rating).

The hybrid induction motor automatically calibrates and prevents the device from overloading and extinguishing due to overload. When the motor approaches the edge of the magnetic overload and flameout, the permanent magnet rotor will disengage from the inductive rotor while maintaining its synchronous speed, and the two will recombine after the transient is removed.

In another embodiment of the invention, the rotor contains a damper coil of a standard induction motor rotor-like acceleration without any negative permanent magnet effect, or A transient current that cuts off the torque and benefits from the positive force applied. This transient current is provided by a slip clutch that is actuated by a permanent magnet rotor through a help torque. This damper coil provides torque without the ripples and vibrations of the LSPM motor at startup.

Furthermore, the hybrid induction motor safely uses a ferrite magnet, so that the clutch device does not have to expose the magnet to the high-pressure demagnetization force, but reduces the magnetic overload condition to a normal state while maintaining the rotational speed of the magnetic disk.

The following description is made in the best mode of the invention. This description is not a limitation of the definition, but merely to describe one or more preferred embodiments of the invention. Inventions in this field should refer to these instructions.

Arrangement combination of induction rotor and permanent magnet rotor: According to the prior invention of Fig. 1, the first embodiment motor 10' has an independent rotating permanent magnet rotor 26, and an induction rotor 20 is coupled to the motor shaft 32 (or other load) and The permanent magnet rotor 26, and the stator coil 12 external to the inductive rotor 20, this independent rotating permanent magnet rotor 26 will be non-fixedly coupled to the inductive rotor 20. When starting the horse At 10', this non-fixed joint causes the independently rotating permanent magnet rotor 26 to accelerate to a synchronous speed in a short period of time. The independent induction rotor 20 coupled to a load will have a slower acceleration speed than the permanent magnet rotor 26. This non-fixed connection may be in the form of a friction clutch, a centrifugal clutch or an electronically controlled clutch, as explained in the following paragraphs. Once the inductive rotor 20 approaches the synchronous speed, it will operate in synchronism with the permanent magnet rotor 26, and the operation of the housing in the inductive rotor 20 will stop generating current, due to the lack of rotating the stator coil magnetic field and the sensing strip sliding in the housing, the motor 10 'It will operate with the same efficiency as a permanent magnet motor.

In accordance with the present invention, in FIG. 2, a second electronic motor structure 10" couples the inductive rotor 20 to the motor shaft 32, and an independent rotating permanent magnet rotor 26 outside the inductive rotor, as well as in an independently rotating permanent magnet rotor. The outer stator coil is connected. This electronic motor structure 10" is similar to the principle electronic motor structure 10' except that the permanent magnet rotor 26 is present outside the inductive rotor 20 in a different configuration (i.e., it is present in the inductive rotor 20 and the stator). Between the coils 12. The permanent magnet rotor 26 constitutes a ring magnet.

The third motor structure 10"' has a stator coil 12 in the rotors 20 and 26, and the independently rotating permanent magnet rotor 26 will be outside the stator coil 12, and the inductive rotor 20 will be load coupled to the permanent magnet rotor 26 and the stator coil 12. The electronic motor structure 10"' is similar in principle to the electronic motor structure 10' except that the stator coils 12 are present in the rotors 20 and 26 simultaneously, and the permanent magnet rotors 26 are typically interposed between the stator coils 12 and the inductive rotors 20. Between the annular magnetic field regions.

The fourth motor structure 10"" has a stator coil 12 in the rotors 20 and 26, and the inductive rotor 20 is load coupled outside the stator coil 12. And outside the induction rotor 20 The permanent magnet rotor 26 will rotate independently, as shown in Figure 4, the structure 10"" of the motor is similar in principle to the electronic motor structure 10' except that the stator coil 12 will be present in both rotors 20 and 26, and the permanent magnet rotor 26 will be outside the induction rotor 20, and the permanent magnet rotor 26 will preferably be composed of a toroidal magnetic field.

At the beginning, the speed and torque per minute associated with the inductive rotor 20 and the permanent magnet rotor 26 are shown in Figure 5. When the electrical energy 40 is output, the permanent magnet rotor torque 48 is rapidly increased, helping the permanent magnet rotor 26 to overcome the hysteresis of the inductive rotor 20, so that the rotor speed 42 of the permanent magnet rotor can quickly reach the synchronous revolutions per minute. As the rotational speed per minute of the inductive rotor speed 44 approaches the synchronous revolutions per minute and the torque 48 drops, the permanent magnet rotor 26 and the inductive rotor 20 are locked into a synchronous per minute rotational speed and the rotor is converted into a permanent magnetic field of high speed effective energy. .

Embodiment of the non-fixed connection induction and permanent magnet rotor Clutch: Figure 6, side view of the stepless slip clutch 34'; Figure 7, end view of the stepless slip clutch 34'. The stepless slip clutch 34' includes a ring plate 52 that is included in the permanent magnet rotor 26 that is urged to the annular friction surface 54 of the inductive rotor 20. The stepless slip clutch 34' and the spring 50 generate friction due to continuous motion. When the permanent magnet rotor torque 48 reaches a peak (see FIG. 5), the permanent magnet rotor 26 is not controlled by the rotational speed of the induction rotor during the starting phase. When the magnetic rotor torque 48 drops, the stepless slip clutch 34' also fixes the rotational speed of the rotors 20 and 26 to the revolutions per minute.

Figure 8 is a side elevational view of the discrete slip clutch 34"; Figure 9 is an end view of the discrete slip clutch 34". Discrete slip clutch 34" includes teeth 59 that are uniformly aligned on ring plate 56, and corresponding tooth marks 58; which enable discrete slip clutches 34" can mesh the relationship between the permanent magnet rotor 26 and the inductive rotor 20, so as to reference the stator coil magnetic field, and can calibrate the rotor pole. When the rotor is in a small number of polar regions, for example, four poles, such discrete calibration is preferred. use.

Figure 10 is a side elevational view of the centrifugal clutch 34"' joining the permanent magnet rotor 26 and the inductive rotor 20; Figure 11 is a cross-sectional view taken along line 11-11 of Figure 10, the centrifugal clutch 34"' joining the permanent magnet rotor 26 and the inductive rotor 20. The blade 60 attached to the inductive rotor 20 extends to a concave cylindrical opening 64 at the bottom end of the permanent magnet rotor 26. The centrifugal rotating block 62 is present in the vane 60 and continues to rotate with the inductive rotor 20. As the rotational speed of the induction rotor 20 reaches the synchronous speed, the centrifugal rotating block 62 is pushed to the inner layer of the cylindrical port 64, thereby fixing the permanent magnet rotor 26 and the induction rotor 20 to the same rotation.

12 is a side view of the electromagnetic clutch 34"" connecting the permanent magnet rotor and the induction rotor 20; FIG. 13 is the electromagnetic clutch 34"" depicted in the section 13-13 of FIG. 11 connected to the permanent magnet rotor 26 and the induction rotor 20. Cutaway view. The electromagnetic clutch 34"" includes a coil (or solenoid) 74 that receives current through the inductive coil 76 within the inductive rotor 20, the coil 74 pushes the clutch guard 70 away from the cylindrical port 64, and the spring 72 pushes the protective sleeve toward the cylindrical shape The inside of the mouth 64. The protective sleeve 70 can be used to provide similar efficacy in place of the centrifugal rotating block 62 as the inner surface of the cylindrical opening 64 when the rotational speed per minute of the inductive rotor is increased as shown in FIG. The current generated by the inductor 76 is proportional to the difference in the number of revolutions per minute and the synchronous speed of the inductive rotor. Therefore, the electromagnetic clutch 34"" is disengaged at the start, and the electromagnetic clutch 34 is engaged when the inductive rotor approaches the synchronous speed every minute." ".
