Driving circuit for a stepping motor |
摘要 |
A driving circuit for a stepping motor has a pair of emitter-connected PNP transistors with the common junction point of the emitters connected to a source voltage. A pair of source-connected static induction transistors each has its drain connected to the collector of one PNP transistor with the connection point being connected to one side of the drive coil of the motor. The leak current characteristic of the static induction transistors along their drain-to-source paths is chosen so that sufficient leak current flows when all four transistors are simultaneously in the OFF state to effectively dampen the motor.
