Description

Connection frame, motor stator and the motor used for it

This creation belongs to the technical field of a motor. Specifically, it refers to a wiring frame, a motor stator, and a motor to which it is applied. It can ensure that the wires are effectively isolated to improve the safety of the motor, and at the same time, it can reduce the overall volume and increase Its ease of use.

According to this, a motor is a motor device that converts electrical energy into kinetic energy. Today, the motor motor industry is one of the modern core industries, and its power and stability are also improving with each passing day. In view of the current industrial needs, the safety of motor use and the reduction of motor size are very important issues. Motor types can be divided into single-phase motors and three-phase motors. Among them, three-phase motors have the advantages of low price, simple structure and no complicated maintenance, so they are widely used in the industrial field. The three-phase motor includes a housing, a motor stator and a motor rotor. The motor stator is fixed in the housing, and the motor rotor is rotatably arranged in the motor stator. When the coil assembly is energized, a rotating magnetic field will be formed, and the rotating magnetic field will drive the motor rotor to produce rotational speed and torque output.

The motor stator of the aforementioned three-phase motor includes an iron core and a plurality of coil groups. The iron core includes a plurality of silicon steel sheets and a plurality of I-shaped parts. The silicon steel sheets are laminated and connected to form a hollow ring column with a considerable thickness. The I-shaped pieces are arranged on the inner circumferential side of the hollow ring cylinder and are arranged at intervals along the inner circumferential side of the hollow ring cylinder. Each wire is wound around the I-shaped piece to form a coil group. The coils The group can be divided into three combinations according to the phase. For example, the four coils with the phase U phase form one combination, the four coils with the phase V phase form one combination, and the four coils with the phase W phase form one combination. , Such three combined coil groups are connected into a Y-shaped connection or a Δ-shaped connection, and then connected to a three-phase power supply. Therefore, in order to avoid incorrect wiring and false touches of the coil group wires that are not in the same phase, generally there is a wire frame at the top of the motor stator to guide the coil group wires of different phases to complete the wire connection operation and facilitate the aforementioned three-phase Power connection.

However, the wiring frame of the existing motor stator is usually tied to the side openings, allowing the wires of the coil groups to enter the different wire grooves of the wiring frame from the side, such as my country Patent Publication No. I681608, Publication No. I708459, etc. There are some problems in the use of the existing connection stand; such as:

1. First of all, because the wires are inserted through the side of the junction frame, the wires of the coil group located below need to be bent and extended to the outer periphery, and then threaded from the side into the corresponding wire troughs of the junction frame. This increases the inconvenience and complexity of threading, and the wires wound around the warp-bonding frame will also increase its outer diameter, which will increase the overall volume and increase the volume of the motor.

2. Secondly, since the three-phase wires need to be wound in different wire troughs of the junction frame, when the wires on the inner wire trough are inserted from the side, they need to cross the outermost and middle wire troughs, in order to avoid errors. To contact, it is usually necessary to carry out structural design on the connection frame. For example, the connection frame of No. I681608 adopts the method of different height positions of the bottom surface of the wire trough to stagger the wires of different phases. As for the connection frame of No. I708459, the adjacent wires are used. The spacers of different heights between the slots are used to stagger the wires of different phases, which will increase the height of the wiring frame, which will also increase the overall volume, thereby increasing the volume of the motor.

3. Furthermore, as mentioned above, the innermost wire needs to cross the outermost and middle wire grooves of the connection frame, and the middle wire needs to cross the outermost wire groove of the connection frame. At this time, in addition to the different heights, the coil group If there is no barrier between the wires, there may be the risk of short circuit between the wires of the coil sets of different phases at any time, causing safety concerns in the use of the motor.

In other words, the existing design of the motor stator's wire frame is not perfect, which leads to difficulties in the wire connection process, complex assembly process, and a significant increase in error rate. In addition, it occupies a large area and affects the size and weight of the motor. The safety problem in use and how to solve the aforementioned problems are what the industry and users expect, and it is also what this creation wants to discuss.

In view of this, the creator has focused on the problems faced by the above-mentioned incumbents, studied and cooperated with the application of academic theory, upholding many years of design, development and practical experience in the related industry, and improved the existing structure in response to the shortcomings of the existing structure, and finally successfully developed A wiring frame, a motor stator and a motor using them can overcome the troubles and inconveniences caused by the existing ones.

Therefore, the main purpose of this creation is to provide a wiring frame, a motor stator and a motor to which they are applied, so that the coil group wires of the motor stator can be effectively separated and threaded into the wiring frame, so as to simplify the threading method and avoid different phases. The wire is touched by mistake, which greatly improves the safety of its use.

In addition, the second main purpose of this creation is to provide a connection frame, a motor stator, and a motor to which they are applied, which can reduce the outer diameter and height of the connection frame to reduce the overall footprint, thereby reducing the volume of the motor.

In addition, another main purpose of this creation is to provide a wiring frame, motor stator, and motor to which they are applied, which can effectively and quickly arrange the wires of the in-phase coil group without having to wrap insulating materials on each of the wires. Effectively simplify production and assembly, and further improve product yield.

Furthermore, another main purpose of this creation is to provide a wiring frame, a motor stator, and a motor to which they are applied, which allows the coil group wires of each phase to be wound in an accurate direction, which further simplifies the complexity of assembly and wiring, and Can effectively reduce its error rate.
