Connecting Motors for Torque Speed and Horsepower Conditions

Home | Articles | Forum | Glossary | Books


The squirrel-cage induction motor can be connected in several different ways to produce constant torque, a change of speed, or a change of horsepower ratings. They can also be connected for variable torque. The load conditions or applications will dictate the method one selects to connect the motor. These connections can be made after the motor is installed on the factory floor or when the motor is being installed in the machinery it's driving. The next sections will provide examples of each way the motor can be connected to make these changes.
