Motor overload protection is essential to ensure the safe, reliable, and long-lasting operation of machinery and equipment that include an electric motor. An overload relay stops a motor from overheating, which can cause damage to the controller, motor, or branch circuit conductors. An overload relay can also reduce the risk of severe failures.
Apr 14, 2021 1. Motor Overload. If your motor is drawing excessive current, showing signs of insufficient torque, or overheating, chances are it’s overloaded. An overload often occurs when the motor provides power than what it was rated for. 2. Short Cycling. Short cycling can occur if the motor is repeatedly turned off and on before it has the chance to cool down.
Electric motors are an integral component of industrial equipment, toys, vehicles, and electronic devices. They are designed to convert electrical energy into mechanical energy. These devices may be powered by AC or DC sources. Blowers, fans, compressors, cranes, extruders, and crushers are a few important devices equipped with electric motors.
