Abstract
One embodiment of a drive system may include a motor shaft coupled to a gear set in connection between an input shaft and an output shaft. The system may also have a direct current motor selectively holding the motor shaft in a fixed position for engaging the input and output shafts to one another in response to a sudden power loss from a main power supply. The system may further include an auxiliary power supply enabling the direct current motor to provide a resistive torque.
