The Ambi-Tech™ Fan-Stop is an electronic motor brake that permits rapid starting of AC motors by first eliminating an effect called “wind-milling” or coasting. The stopping action is done by DC injection braking, which creates a stationary magnetic field within the motor. Braking action is smooth, adjustable, and frictionless. The brake will be engaged briefly prior to starting the motor. The Fan-Stop motor brake is specially intended for applications such as fans where the motor may be wind-milling in reverse prior to the motor receiving a command to run. By braking the motor to a stop, mechanical stress on the powertrain or motor is eliminated.
