Abstract: An example electromagnetic actuator includes a drive shaft, a motor operable to rotate the drive shaft, and a load shaft coupled to an armature body. A clutch is operable to control whether the drive shaft engages the load shaft. A rotatable portion of the clutch corotates with the drive shaft and includes a field winding and a clutch body. A stationary portion of the clutch includes an exciter winding that is inductively coupled to the rotatable portion and is operable to energize the field winding. The field winding is operable, when energized, to provide a magnetic field that causes engagement or disengagement between the clutch body and an armature body. A method of operating an electromagnetic actuator is also disclosed.

Abstract: Provided is a motor drive device including: a current detector that detects a current flowing through a power line supplying power to a brake-equipped motor; and a controller that controls the brake-equipped motor based on the current value detected by the current detector. The controller includes a determination part that determines, when actuating the brake-equipped motor whose brake is in a braking state, states of the power line and the brake-equipped motor, based on the current value detected by the current detector after applying a voltage between the power lines. The controller outputs a release instruction signal for releasing the brake when the determination part determines that the states are normal.
