The W01 brake motor line has been designed for equipment and applications that require fast stops for safety, accurate positioning and time saving. This is possible since the brakes are locked with springs and electrically released. It also provides the brake operation when failures are presented, such as interruption or failure on the power supply, so the brake will hold the load as protection. These motors are the best option to operate applications requiring safety stop and, thanks to its AC brakes, dispensing the use of rectifiers.
