Single phase bipolar stepping motor having two rotation senses |
摘要 |
The invention comprises a single phase bipolar stepping motor in which the rotor may rotate in both senses. A stator is provided having two windings. When these are connected in series and fed with a first type of alternating polarity pulses, the rotor turns in a preferred sense. When the windings are connected in parallel and fed by a second type of alternating polarity pulses of opposite phase to the first type the rotor turns in the opposite sense. The motor is applied to advantage in time setting arrangements for analog display timepieces.
