Description
Technical Field
[0001] This utility model relates to the field of permanent magnet assisted synchronous reluctance motor technology, and in particular to a speed control device for a permanent magnet assisted synchronous reluctance motor. Background Technology
[0002] A permanent magnet assisted synchronous reluctance motor is a type of motor that combines the advantages of permanent magnet motors and synchronous reluctance motors. It consists of a stator and a rotor. The stator is made of laminated silicon steel sheets, while the rotor is made of laminated samarium cobalt or neodymium iron boron permanent magnets and silicon steel sheets, forming a reluctance stepper motor. A speed controller for a reluctance motor is a device used to adjust the motor's speed. The main function of a reluctance motor speed controller is to achieve speed regulation by changing the motor's magnetic circuit. Common reluctance motor speed controllers include electromagnetic speed controllers and frequency converter-type speed controllers.
[0003] The existing technical solutions mentioned above have the following drawbacks: the existing reluctance motor speed controllers lack a safety protection structure, cannot effectively protect the speed controller, and have low practicality. Utility Model Content
[0004] The purpose of this invention is to provide a speed control device for a permanent magnet assisted synchronous reluctance motor.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A speed control device for a permanent magnet assisted synchronous reluctance motor includes a base, the base having a sliding groove inside, a first protective cover and a second protective cover inside the base, both the first and second protective covers having identical sliders fixedly connected to their outer sides, a first magnet fixedly connected to the outer side of the first protective cover, a second magnet fixedly connected to the outer side of the second protective cover, and a speed controller body installed at the center inside the base.
[0007] By adopting the above technical solution, sliding protective covers are added to both sides of the base. The protective covers can be attached by magnetic attraction, which is convenient for operation and use, and protects the internal speed controller. The protective covers can be opened at any time to facilitate the inspection and operation of the speed controller.
[0008] Furthermore, a first handle is fixedly connected to the outer side of the first protective cover, a second handle is fixedly connected to the outer side of the second protective cover, a limiting plate is provided on the outer side of the base, a slot is provided inside the limiting plate, and a housing is fixedly connected to the outer side of the first protective cover.
[0009] By adopting the above technical solution, the handle design allows for easy opening of both sets of protective covers, making operation more convenient. At the same time, the addition of a limiting plate prevents the protective covers from falling off the base.
[0010] Furthermore, a fan is fixedly connected inside the housing, a heat dissipation hole is reserved on one side of the outer side of the housing, a dustproof net is fixedly connected to the other side of the outer side of the housing, and a mounting block is fixedly connected to the outer side of the base.
[0011] By adopting the above technical solution and adding a fan, the heat dissipation effect inside the protective cover can be accelerated, ensuring the normal heat dissipation and use of the speed controller.
[0012] Furthermore, the slider and the groove are slidably connected, the first protective cover and the second protective cover are the same size and have the same specifications, and the first magnet and the second magnet are magnetically connected.
[0013] By adopting the above technical solution and adding two sets of sliding protective covers, the speed controller can be protected.
[0014] Furthermore, there are two limiting plates, the two ends of the outer side of the base are respectively engaged with the slots, the interior of the shell and the interior of the first protective cover are interconnected, and multiple heat dissipation holes are provided at equal intervals.
[0015] By adopting the above technical solution, the limiting plate can prevent the protective covers at both ends from slipping off from both sides, ensuring the stability of the structure and normal use.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] It adopts a protective cover and a fan. By installing a speed controller on the base, and adding sliding protective covers at both ends of the speed controller, the protective covers at both ends can protect the speed controller and can be attached by magnets. During use, the external fan can dissipate heat from the inside. It can protect the controller without affecting normal heat dissipation, resulting in a convenient user experience.

Sliding protective covers are added to both sides of the base 1. The protective covers can be attached by magnetic attraction for easy operation and protection of the internal speed controller. The protective covers can be opened at any time for easy maintenance and operation of the speed controller. A fan 14 is added to accelerate the heat dissipation inside the protective cover and ensure the normal heat dissipation of the speed controller. The limiting plate 11 and the outer ends of the base 1 are interference fit connections to ensure the firmness of the connection structure.
[0026] like Figure 1-5 As shown, a fan 14 is fixedly connected inside the housing 13. A heat dissipation hole 15 is reserved on one side of the outer side of the housing 13. A dustproof net 16 is fixedly connected to the other side of the outer side of the housing 13. An installation block 17 is fixedly connected to the outer side of the base 1.
