Research on the Failure Mechanism and Solution Strategy for Friction Braking of Electric Hoists

The electromagnetic braking motor, which combines cylindrical motors with electromagnetic brakes, has gradually been widely used in the lifting mechanism of electric hoists. This configuration of electric hoists usually has a large difference in lifting speed between fast and slow, and the highest speed can reach the lowest speed Liu Bei. During the process of rapid sudden braking and sudden switching between fast and slow speeds, it is easy to generate a large amount of braking slip, posing a huge challenge to friction braking. In response to the issue of excessive brake slip of a wire rope electric hoist, the mechanism causing the excessive brake slip was analysed, and a solution was provided. This paper analyses the methods of shortening braking time and reducing braking slip from mechanical, electrical, and control aspects, with a focus on the impact of rectifier and brake response delay on braking deceleration
time and braking slip amount.
