Reversible motors have a higher starting torque compared to normal Induction motors to help it reverse directions quickly. This, in addition to the heat caused by the brake mechanism of the Reversible motor, makes the motor very hot and hence a 30 min. “ON” time (regardless of direction) rating. The key factors are the ambient temperature and duty cycle %. As long as the motor case temp. is below 90°C, you can safely increase the duty cycle % and/or the 30 minute rating.
