ELECTROMAGNETIC ACTUATOR

摘要

An electromagnetic actuator is capable of providing a high speed driving force, for example, for driving the contacts of a circuit breaker or similar power distribution equipment. The electromagnetic actuator may use a directly powered moving coil element in combination with one or more energized stationary coils to generate an output force usin g reduced requirements for current, voltage and current/voltage rate-of-change. Precis e control of actuator motion is obtained by permitting different supply voltages, firing times and capacitor supplies. The electromagnetic actuator may further incorporate a return spring arrangement and a magnetic latch arrangement.
