Stepping motor with plastic bottom cover and plastic packaging method thereof

Abstract

The invention discloses a stepping motor with a plastic bottom cover and a plastic packaging method thereof. The stepping motor comprises a stepping motor body, a positioning bottom cover is fixedly arranged at the bottom end of the stepping motor body, first positioning frames are fixedly arranged at the two ends of the bottom of the positioning bottom cover correspondingly, and supporting bases are fixedly arranged at the bottom ends of the two first positioning frames correspondingly; the bottom ends of one sides of the two supporting seats are fixedly provided with positioning plates, and first through grooves are formed in the middle positions of the tops of the positioning plates. By rotating a first positioning handle, the first positioning handle drives a lead screw at one end to rotate, and the lead screw rotationally connected to one sides of the two positioning seats drives a moving block in threaded connection with the outer wall to move; and the moving block drives two induced draft fans at the top end to slide along the first through grooves and the second through grooves respectively, so that the stepping motor body and a plastic package seat at the bottom end of the stepping motor body can be positioned and cooled conveniently, the working efficiency of the stepping motor body is improved, and the service life of the plastic package base of the stepping motor body is prolonged.

Description

technical field [0001] The invention relates to the field of stepping motors, in particular to a stepping motor with a plastic bottom cover and a plastic sealing method thereof. Background technique [0002] A stepper motor is a motor that converts electrical pulse signals into corresponding angular displacement or linear displacement. Every time a pulse signal is input, the rotor rotates an angle or advances one step, and the output angular displacement or linear displacement is proportional to the number of input pulses. Proportional, the speed is proportional to the pulse frequency, therefore, the stepper motor is also called the pulse motor. [0003] In the prior art, the lower crimping cover of the traditional motor is made of aluminum cover. When the stepper motor is used on the sewing machine, it is difficult to achieve the sealing effect when the stepper motor is installed, resulting in It is easy to drop substances such as engine oil on the motor, which will affect...

Problems solved by technology

[0003] In the prior art, the lower crimping cover of the traditional motor is made of aluminum cover. When the stepper motor is used on the sewing machine, it is difficult to achieve the sealing effect when the stepper motor is installed, resulting in It is easy to drop the oil and other substances on the motor, which will affect the service life of the motor, and the high temperature and local high temperature caused by the operation of the motor will reduce the efficiency of the motor, so a stepper motor with a plastic bottom cover is required
