提供了一种具有定时自动间歇换向功能的电动机控制装置。该装置由弱电控制电路和强电控制电路两部分组成。将现行的集成电路时间继电器进行改造,使用AT89C2052单片机构成了具有循环定时间歇换向控制的弱电控制装置,弱电控制电路即该装置的内部电路。由上述弱电控制装置配合强电部件构成了强电控制电路。该装置具有电路简单、操作简便、成本低的优点。
A motor control device with a timed automatic intermittent commutation function is provided. The device consists of weak control circuit and strong control circuit composed of two parts. The current integrated circuit time relay to be modified, the use of AT89C2052 microcontroller has become a cyclical intermittent switching control weak electric control device, weak control circuit that is the device’s internal circuitry. The weak electric control device cooperates with strong electric components to form a strong electric control circuit. The device has the advantages of simple circuit, simple operation and low cost.
