STEPPING MOTOR AND TIMEPIECE PROVIDED WITH STEPPING MOTOR |
| 摘要 |
Disclosed is a stepping motor including a rotor, a plurality of coils and a switching mechanism. The stepping motor simultaneously or sequentially applies driving pulses to the coils to rotate the rotor by a predetermined step angle, and while the driving pulses are being applied to part of the coils, the switching mechanism switches the rest of the coils other than the part of the coils driven by the driving pulses into a high impedance state. |
