Short cycling can occur if the motor is repeatedly turned off and on before it has the chance to cool down. To help avoid this problem, most electric motor manufacturers specify the maximum number, or frequency, of starts for a given motor type. 3. Electrical Supply. A voltage imbalance can result in a motor to overheat.
