专利汇可以提供Controlling method for synchronous motor专利检索,专利查询,专利分析的服务。并且PURPOSE:To control the speed of the synchronous motor readily and to perform fine, responsive control, by providing a pulse encoder, a reversible counting means, and a converting means, and generating the phase of induced electromotive voltage. CONSTITUTION:The pulse encoder 2 outputs both a position pulse train and rotary pulses. An up down counter 4 presets the position of the rotor of the synchronous motor 1 by the position pulse train and performs reversible counting by the rotary pulse. A DA converter 6 converts the value of costheta and the value of sintheta corresponding to the counted values of the counter 4 into analog voltages. In this way, the phase of the induced electromotive voltage is generated and the synchronous motor 1 can be controlled by the similar way as a DC motor. Therefore the speed control can be performed more readily, torque generation control can be facilitated, and the fine responsive control can be performed.,下面是Controlling method for synchronous motor专利的具体信息内容。
