[0002] A reluctance motor is a continuously operating electric drive device. Its structure and working principle are very different from those of traditional AC and DC motors. It does not rely on the interaction of magnetic fields generated by stator and rotor winding currents to generate torque, but relies on the "principle of minimum reluctance" to generate torque. When the reluctance motor is working, it needs to be effectively controlled by a controller.
[0003] The existing controllers have limitations in internal component damping and convenient maintenance operations. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a permanent magnet assisted synchronous reluctance motor controller that can perform damping filtering operations, has high overall practicality, and can conveniently perform maintenance operations on the interface.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A permanent magnet assisted synchronous reluctance motor controller includes a housing base. A plurality of damping telescopic rods are fixedly installed on the inner end face of the housing base. The upper ends of the damping telescopic rods are fixedly installed with an inner mounting frame. Springs are sleeved outside the damping telescopic rods. A control circuit board is fixedly installed on the upper surface of the inner mounting frame. One end of the control circuit board is provided with second wiring terminals. An outer mounting seat is fixedly connected to the end face of the housing base. A plurality of first wiring terminals are snap-fitted inside the outer mounting seat. The first wiring terminals and the second wiring terminals are electrically connected.

[0008] Further, a limiting frame is sleeved outside the outer mounting seat.
[0009] By adopting the above technical solutions, a plurality of first wiring terminals can be limited and fixed.
[0010] Further, an upper mounting frame is fixedly connected to the upper edge of the housing base. Mounting holes are provided on the upper surface of the upper mounting frame, and a cooling fan is fixedly installed inside the mounting holes.
[0011] By adopting the above technical solutions, the rotation of the cooling fan can be used to realize air flow, and thus active heat dissipation operations can be realized.
[0012] Furthermore, a heat dissipation cover is installed on the outer cover of the shell base. A slot is provided at one side edge of the upper surface of the heat dissipation cover, and the upper mounting frame is inserted into the slot.
[0013] By adopting the above technical solution, the installation is convenient, and the internal components of the controller can be protected.
[0014] Furthermore, a plurality of internal heat conduction strips are fixedly connected to the inner wall of the heat dissipation cover, and a plurality of air guide holes are provided inside the heat dissipation cover.
[0015] By adopting the above technical solution, effective air flow can be achieved, and thus effective heat dissipation operation can be realized.
[0016] Furthermore, rubber strips are pasted on the lower surface of the shell base, and a plurality of mounting holes are provided at the edges of the shell base, and a circular rubber block is pasted at both ends of each mounting hole.
[0017] By adopting the above technical solution, the installation stability can be improved, and at the same time, insulated installation can be realized.
[0018] In summary, the beneficial technical effects of the present utility model are as follows:
[0019] 1.

[0020] 2. During the use of the present utility model, the heat dissipation fan can be started. The rotation of the heat dissipation fan enables the external air to orderly pass through the air guide holes inside the heat dissipation cover. Under the conduction of the internal heat conduction strips, the interior of the controller can be effectively cooled, and during the heat dissipation process, external air can be effectively prevented from entering the interior of the controller, thereby avoiding damage to the internal structure of the controller by water vapor, and the overall practicability is strong.

At the same time, the settings of the first terminal 8 and the second terminal 16 enable flexible electrical connection operations and flexible disassembly operations, which are convenient for the replacement of accessories and have high flexibility in maintenance.
[0027] Refer to Figure 1 , Figure 2 , Figure 3 , at the upper edge of the shell base 1, an upper mounting frame 10 is fixedly connected. On the upper surface of the upper mounting frame 10, mounting holes are provided, and a cooling fan 11 is fixedly installed inside the mounting holes. A cooling cover 12 is buckled outside the shell base 1. On one side edge of the upper surface of the cooling cover 12, a slot 13 is provided. The upper mounting frame 10 is inserted into the slot 13. A plurality of inner heat conduction strips 14 are fixedly connected to the inner wall of the cooling cover 12. A plurality of air guide holes 15 are provided inside the cooling cover 12. Among them, during use, the cooling fan 11 can be started. The rotation of the cooling fan 11 enables the external air to orderly pass through the air guide holes 15 inside the cooling cover 12. Under the conduction of the inner heat conduction strips 14, effective heat dissipation can be carried out on the inside of the controller, and during the heat dissipation process, it can effectively prevent external air from entering the inside of the controller, thereby avoiding damage to the internal structure of the controller by water vapor, and the overall practicality is strong.

[0029] Working principle: When in use, first install the controller at a specified position. Since a plurality of damping telescopic rods 2 and springs 3 are provided inside the housing base 1, the control circuit board 6 mounted on the inner mounting frame 5 can be shock-absorbed, ensuring that the internal structure of the controller will not be damaged when passing through a bumpy road section. Then, during the use process, start the cooling fan 11. The rotation of the cooling fan 11 enables the external air to orderly pass through the air guide holes 15 inside the cooling cover 12. Under the conduction of the inner heat conduction strip 14, effective heat dissipation can be carried out on the inside of the controller, and during the heat dissipation process, it can effectively prevent the external air from entering the inside of the controller, thereby avoiding damage to the internal structure of the controller by water vapor. When maintenance is required, the limit frame 9 can be opened, and the first wiring terminal 8 can be quickly disassembled, so as to conveniently repair the connection port.
