Abstract
Description
Technical Field
[0001] This utility model relates to the field of stepper motor technology, and in particular to a high-precision closed-loop control structure for stepper motors. Background Technology
[0002] A stepper motor is a type of electric motor that converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Therefore, stepper motors are also called pulse motors. The development of the stepper motor industry has gradually evolved from traditional ordinary stepper motors to closed-loop stepper motors with added encoders, which have greatly improved speed and accuracy.
[0003] Existing stepper motor cooling relies on heat dissipation fins on the protective cover to conduct heat out of the motor body. This cooling method is ineffective in the long-term use of stepper motors, resulting in excessively high internal temperatures. This can easily cause the circuit of the closed-loop control structure to burn out due to high temperatures, shortening the service life of the closed-loop stepper motor and failing to meet the user's needs.
[0004] Therefore, there is an urgent need to provide a high-precision closed-loop control structure for stepper motors to solve the above problems. Utility Model Content

[0007] Through the above technical solution, the closed-loop control module drives the stepper motor body to operate according to the set instructions. The sound-absorbing felt and the noise-reducing inner shell work together to insulate and reduce noise from the stepper motor body, thereby reducing noise pollution during use.
[0008] The present invention is further configured such that: the reinforcement mechanism includes a motor flange fixed to the outside of the stepper motor body, and a noise reduction shell is fixed to one side of the motor flange by a mounting bolt thread.
[0009] The above technical solution protects the stepper motor body with a noise-reducing shell, and the shell can be quickly disassembled and assembled with mounting bolts, thereby enabling maintenance of the stepper motor body.

[0011] The above technical solution improves the structural strength of the mounting plate by reinforcing ribs, which can effectively suppress the strong noise caused by resonance of the stepper motor body.
[0012] The present invention is further configured such that: the water cooling mechanism includes four mounting posts fitted between the noise reduction inner shell and the stepper motor body, and a water cooling plate is fixedly connected between the four mounting posts.
[0013] Through the above technical solution, the water-cooled plate can cool the stepper motor body and the closed-loop control module, so that the closed-loop stepper motor can work within a relatively stable temperature range.
[0014] The present invention is further configured such that: a water-cooled inlet pipe is fixedly installed on one side of the water-cooled plate, and a water-cooled outlet pipe is fixedly installed on one side of the water-cooled plate.
[0015] The above technical solution uses water-cooled inlet pipes and water-cooled outlet pipes to circulate and cool the water-cooled plate.
[0016] The present invention is further configured such that: an inlet main pipe is fixedly installed at the other end of the water-cooled inlet pipe, and an outlet main pipe is fixedly installed at the other end of the water-cooled outlet pipe.
[0017] The above technical solution allows for the circulation of water-cooled inlet and outlet pipes through the inlet manifold and outlet manifold, respectively.
[0018] The present invention is further configured such that: the installation mechanism includes a housing fixing plate fixed to one side of the water-cooled inlet pipe and the water-cooled outlet pipe, one side of the housing fixing plate is threadedly fixed to the noise-reducing shell flange by fixing bolts, and a water-cooled threaded connector is fixedly installed on one side of the inlet main pipe and the outlet main pipe, and the outside of the water-cooled threaded connector is fixedly connected to the inside of the housing fixing plate.
[0019] Through the above technical solution, the water-cooled equipment provides a connector for connection with the water-cooled threaded connector, and the connection and fixation are achieved through the threaded ring. At the same time, the outer casing fixing plate can be quickly disassembled and assembled through the fixing bolts, thereby enabling maintenance of the water-cooling mechanism.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. This utility model, by providing a water-cooling mechanism and an installation mechanism, can perform water-cooling heat dissipation on the stepper motor body and the closed-loop control module, so that the closed-loop stepper motor can operate within a relatively stable temperature range, thereby improving the efficiency and reliability of the closed-loop stepper motor, reducing the risk of failure due to overheating, and extending its service life.
[0022] 2. This utility model, by providing a reinforcement mechanism, can insulate and reduce noise from the stepper motor body, thereby reducing noise pollution during use. At the same time, the enhanced rigidity design increases the structural strength of the mounting base, which can effectively suppress the strong noise caused by resonance, making the entire mechanism more robust and reliable.
