Title:
ELECTROMECHANICAL DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/131077
Kind Code:
A3
Abstract:
An illustrative access control system includes a locking assembly operable in locked and unlocked states, and a drive assembly operable to actuate the locking assembly. The drive assembly includes an electromechanical actuator, and energy storage device, and a control system. The electromechanical actuator is operable, upon receiving power, to transition the locking assembly between the locked state and the unlocked state. The energy storage device is electrically coupled to the electromechanical actuator, and configured to store electrical power from the power supply when the drive assembly is coupled to the power supply. The control system is configured to couple the drive assembly to the power supply in response to a first condition, and to thereafter transmit energy only from the energy storage device to power the electromechanical actuator, based at least in part upon a level of energy stored in the energy storage device.
