Electromagnetic actuator with electromagnet

摘要

The electromagnetic actuator 1 has a coil 2 coupled to a power supply stage 8 and an armature 4 with an integral pin 5 that is displaced linearly. In addition the unit has a braking action coil 3 coupled to a switch 10. As the armature approaches the pole 12, a voltage is induced that causes the switch to close and full braking current is supplied to the coil to provide braking action
