What exactly does the 30-minute rating mean on reversible motors?
Compared to induction motors, reversible motors have a higher starting torque due to a higher capacitor value. This allows them to reverse directions instantaneously. The key factors for a 30 min. ON time (regardless of direction) rating are the ambient temperature and duty cycle %. As long as the motor case temperature is below 90C, you may safely increase the duty cycle % and/or the 30-minute rating.
