Abstract

The utility model discloses a motor, which has a stator coil without an iron core and has no magnetic loss and eddy loss. The technical scheme includes that the motor comprises a stator and rotors, the stator coil is fixedly sealed by plastics to form a rigid integral and fixedly connected with a shell, disk-like rotors are sleeved on motor shafts on two sides of the stator coil respectively, permanent magnets in same number and opposite to the stator coil are evenly distributed on the upper portion of each disk-like rotor along the circumferential direction, the permanent magnets of each disk-like rotor are arrayed in an N-S magnet staggered manner, and the permanent magnets of the disk-like rotors on the two sides of the stator coil are opposite in position and in magnetism. Compared with the prior art, the motor has the stator coil without the iron core, is light in weight and has no magnetic loss and eddy loss.

Description

A kind of motor

Technical field:

The utility model relates to a kind of motor, particularly a kind of motor that does not have magnetic hysteresis and eddy current loss.

Background technology:

The stator coil of existing motor is cored, has magnetic loss and eddy current loss, and the efficient of motor is low, and quality is heavy, and consumptive material is many.

Summary of the invention:

The utility model purpose provides the motor that a kind of stator coil does not have iron core, no magnetic loss and eddy current loss.The technical solution of the utility model is, a kind of motor, comprise stator and rotor, it is characterized in that: described stator coil is that rigid unitary and casing are connected by the plastics sealing, on the motor reel of stator coil both sides, respectively be arranged with a disk type rotor, it is relative with stator coil that the top of each disk type rotor is uniformly distributed with the identical permanent magnet of quantity along the circumference, the permanent magnet of disk type rotor is the N magnetic and the S magnetic is staggered, and the permanent magnet on the disk type rotor of stator coil both sides relatively and different in nature each other magnet.The utility model has stator coil compared with the prior art and does not have iron core, light weight and do not have magnetic loss and the remarkable advantage of eddy current loss.

Description of drawings:

Fig. 1 is the structural representation of the utility model motor, and Fig. 2 is the utility model stator coils of motor schematic diagram, and Fig. 3 is the utility model motor rotor structure schematic diagram, and Fig. 4 is the structural representation of the utility model three-phase stator coil motor arranged side by side.

Embodiment:

Stator coil 3 is hollow winding coil, adopting the material of good heat resistance is that rigid annular integral body is connected with casing 5 with hollow winding coil plastic packaging, rotor 1 is a dish type, the centre bore and the rotating shaft 6 of dish are connected, the permanent magnet that is uniformly distributed along the circumference on the rotor disk of the both sides of stator is relative with stator coil, N utmost point magnetic 2 uniform on the disk body of described rotor is interspersed with S utmost point magnetic 4, and the rotating shaft rotational support is in casing two stomidiums.

The magnetic field of the utility model motor is the axial magnetic field direction, is different from the radial magnetic field orientation of common motor; Stator coil does not have iron core, and motor does not exist magnetic hysteresis loss and eddy current loss, thereby has better energy-saving effect; Stator coil does not have iron core, and its inductance is little, helps the controller circuitry design; The inductance of winding is little, and rotating speed, torque control and adjusting function are more superior for improving; The electric motor structure compactness, volume is little, saves material.

Motor of the present utility model can be made single-deck (as shown in Figure 1), also can make three disc types (as shown in Figure 4) or the above version of three dishes.
