摘要：
A driving circuit for brushless motor has a measure for damping the motor with both upper side and lower side power MOSFET's of half-bridges in pairs which corresponding to three phase coils in bipolar system rendered to be in reverse operating state by turning off a single control power source. The circuit is thereby made realizable an effective motor damping with a simpler circuit structure.
