Abstract

The invention discloses a motor control circuit and method based on a single-chip microcomputer 89c2051. The motor control circuit and method are mainly applied to a small motor control system. The circuit comprises the single-chip microcomputer 89c2051, a power supply, a reset circuit, a crystal oscillator circuit, a motor, a motor control circuit and a control button. The single-chip microcomputer 89c2051 is respectively connected with the power supply, the reset circuit, the crystal oscillator circuit, the motor control circuit and the control button, and the motor control circuit and the motor are connected. The motor control circuit has the advantages that the size is small, power consumption is low, chip development cost is low, and the circuit is simple, suitable for the largely-popularized small motor control system and stable in working.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a small motor system based on a single-chip microcomputer. Background technique [0002] In modern electrical appliances and installations, there is often a small control system. The system mainly consists of a small DC motor, control circuit board and various switches. Through the control circuit, the forward and reverse rotation of the motor and the adjustment of different speeds are realized, so that it can be switched between different rotation modes. Similar control systems have been implemented by engineers using PLC controllers in the past. Because the PLC controller is easy to operate, and the programming of the program is relatively simple. However, this controller has disadvantages, such as high cost, and the value of a PLC controller is thousands of yuan. In addition, the PLC controller is relatively large in size and consumes more power. With the advancement ...
