ABSTRACT:
A control system for an electromagnetic brake, including an electromagnetic brake actuator coil surrounding a power input shaft for a multiple-ratio transmission in a vehicle powertrain. An electromagnetic flux flow path for the actuator coil is electromagnetically isolated from the power input shaft and other elements of the powertrain thereby avoiding residual magnetization. A thermally responsive circuit protector is provided in the coil circuit that senses the temperature of the stator coil to avoid overheating of the stator coil. An overcurrent protector is provided for opening the stator coil circuit when current in the stator coil exceeds a predetermined value.
