STEPPING MOTOR DRIVE METHOD AND APPARATUS |
摘要 |
<p>A driver circuit for controlling the excitation of a multi-phase stepping motor is described which includes a switching power supply providing two average power output levels. The switching power supply provides a high voltage at the initiation of each excitation of a motor winding and a modulated voltage having an average at the normal operating level. The driver according to the invention eliminates need for dual power supplies and damper resistors.</p> |
