ABSTRACT:
The electronic governor has a fast response time by eliminating the return spring of prior art governors. Instead, a magnetic field generated either by permanent magnets or by a second actuator coil is used to oppose the force created by a first actuator coil. The current to the first actuator coil is pulse width modulated. If a second coil is used instead of permanent magnets, the current to the second coil may be either pulse width modulated or may be a constant DC signal. An actuator having a low inertia rotor and a stationary core is preferred to further reduce the response time.
