Design of Motor Starting Device Based on Principle of Winder Energy Storage

摘要

In order to solve the problems of short service life, high energy consumption, and low efficiency of small and medium-sized motors due to the continuous heating by frequent start-stop, we designed a motor starting device based on the principle of winding springs to assist motor starting. The device uses a clockwork to recover the remaining kinetic energy after the motor is de-energized. When the motor is started again, the clockwork releases the elastic potential energy driving the motor to rotate to a certain speed, and then turns on the motor power, this can achieve the purpose of "current reduction and torque protection" .The device has the advantages of high energy conversion efficiency and low cost, can be used without changing the overall layout of the original equipment and does not affect the normal operation of the motor, and is easy to promote.
