摘要： 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.

摘要： A system and method of a variable speed cooling fan (30) for a skid mounted compressor (22). A magnetic variable speed clutch (38) is mounted to the cooling fan drive shaft (28). The clutch mechanism is driven via by a drive pulley (38) on the crankshaft of the engine (24) driving the compressor (22). The speed of the fan (30) is varied dependent upon the temperature of the fluids being cooled.

摘要： A current whose magnitude corresponds to first pressing force-current characteristics set to prevent forward movement of a driven member from being stopped is applied to a motor when the driven member moves forward, and a current whose magnitude corresponds to second pressing force-current characteristics set to move the stopped driven member forward is applied to the motor when the driven member is stopped, in the case where a relationship between a pressing force as a force with which a friction member presses a rotating body and an energization current to the motor is defined as pressing force-current characteristics.

摘要： 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.
