    摘要： An electronic pulse generator has a permanent magnet driven by a shaft and a stationary Hall generator in operative proximity with the magnet. The base electrode of a transistor is directly connected to one of the Hall voltage electrodes of the Hall generator. The stator winding of a stepping motor is connected to the emitter-collector circuit of the transistor, is driven by the Hall voltage via the transistor, and in turn drives a speedometer coupled to the transistor.
