Locked Rotor Current (also DOL Current): The amount of current a motor will draw in a locked rotor situation. Locked rotor current is described as a percentage of full load current, and is the amount of current the motor will draw during a full voltage start.
Locked Rotor Time: The maximum amount of time a motor can safely run at locked rotor current.
Locked Rotor Torque (also DOL Torque): The amount of torque a motor will produce in a locked rotor situation (at locked rotor current). Locked rotor torque is described as a percentage of full load torque, and is the amount of torque the motor will produce during a full voltage start.
