Description

Technical Field

[0001] This utility model relates to an improved invention of an electric motor, and more particularly to an improved invention of an internal cable arrangement structure of an electric motor. Background Technology

[0002] The cables inside the motor pass through the motor housing axially. Due to the lack of restraint or shielding, they are susceptible to damage from contact with the rotor, affecting the motor's quality and lifespan. Furthermore, the existing magnetic bearing clamps, with their raised sections supporting the bearings, have limited space and cannot accommodate cable passage. In other words, there is neither the possibility nor the intention to pass cables through the raised sections of the magnetic bearing clamps. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cable arrangement structure inside a motor.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the internal cable arrangement structure of the motor includes a motor housing, a motor end cover, a rotor, a circuit board, a cable, bearings, and a magnetic clamp. The magnetic clamp is matched and supported between two adjacent bearings, and the magnetic clamp is attached to the inner wall of the motor housing. The magnetic clamp has at least one raised portion, which forms a support for the bearings, and a cable routing channel is formed between the raised portion and the motor housing. One end of the cable is connected to the circuit board at the bottom of the motor housing, and the other end of the cable passes through the top of the motor housing.

[0005] The raised portion has a left raised portion and a right raised portion, and an installation channel is formed between the left raised portion and the right raised portion for the motor end cover bolt to pass through.

[0006] The shape of the raised portion is adapted to the outer circle of the cable.

[0007] The motor housing has a notch at the upper end, which corresponds to the upper end of the raised part, and the notch is matched with the size of the cable.

[0008] Both the bearing bush and the magnetic bearing clip have two pieces.

[0009] The beneficial effect of this utility model is that the improved internal cable arrangement structure of the motor and the reasonable setting of the size and shape of the raised part of the magnetic tile clamp make it suitable for the cable to become a cable routing channel, so as to protect the cable from the rotor and play an effective protective role, thus extending the service life of the motor. Attached Figure Description

[0010] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model.

[0012] Figure 2 This is a cross-sectional view of the structure of this utility model.

[0013] Figure 3 This is an internal structural view of the present invention. Detailed Implementation

[0014] The accompanying drawings illustrate the structure of this utility model, and further details will be described below in conjunction with the drawings. In this embodiment, the components included in the drawings... Figure 1-3 The internal cable arrangement structure of the motor includes a motor housing 1, a motor end cover 2, a rotor 3, a circuit board 4, a cable 5, bearings 6, and a magnetic clamp 7. The motor housing 1 is covered with motor end covers 2 at both axial ends, and the motor end covers 2 are connected by bolts 8. The magnetic clamp 7 is matched and supported between two adjacent bearings 6, and the magnetic clamp 7 fits against the inner wall of the motor housing 1. The magnetic clamp 7 has at least one raised portion 9, which is bent and forms support for the bearings 6. A cable 5 routing channel is formed between the raised portion 9 and the motor housing 1. The corresponding raised portion 9 has a suitable size and shape. The cable 5 is arranged in the cable 5 routing channel. One end of the cable 5 is connected to the circuit board 4 at the lower part of the motor housing 1, and the other end of the cable 5 passes through the upper end of the motor housing 1. Preferably, the upper end of the motor housing 1 has a notch 10, which corresponds to the upper end of the raised portion 9. The notch 10 matches the size of the cable 5 so that the cable 5 can pass through the notch 10. The cable 5 is placed inside the raised part 9 of the magnetic tile clamp 7 to protect the cable 5 from contact with the rotor 3, thus providing effective protection.

[0015] As a further improved specific implementation, the raised portion 9 is provided with a left raised portion 9 and a right raised portion 9, and an installation channel is formed between the left raised portion 9 and the right raised portion 9 for the bolt 8 of the power supply end cover 2 to pass through. The structure is reasonably arranged and facilitates the installation of the bolt 8.

[0016] As a further improved embodiment, the shape of the raised portion 9 is adapted to the outer circle of the cable 5, so that the cable 5 can pass through and form a binding and protection for the cable 5.

[0017] As a further improved embodiment, both the bearing 6 and the magnetic clamp 7 are provided in two pieces, with the two ends of the two bearing 6 supported by the magnetic clamp 7 respectively.

[0018] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
