Problems solved by technology

In some stamping fields, many processes are very dangerous. The principle of the stamping industry is to use the weight of the punching machine for production. However, in practice, stamping robots are often overused and used for a long time, resulting in the failure of the stamping robot. The temperature is too high and the heat dissipation is insufficient. At present, the best heat dissipation method is PWM drive heat dissipation, but the motor of the stamping robot uses a large power environment, and the acquisition and drive error of the general PWM signal is relatively large, which is not suitable for the stamping robot drive heat dissipation.
