Abstract

The invention discloses a speed regulation and reduction motor driving device and a driving method. The device comprises a motor coil; a motor start-stop control speed regulation circuit which is connected with the motor coil and is used for controlling the motor coil to start and stop; and a charging and discharging brake circuit which is connected with the motor coil and is used for providing direct current for the motor coil, so the motor coil is completely stopped. The speed regulation gear motor driving device is suitable for a speed regulation type gear motor with a speed ring, and motor starting can be achieved. In addition, a parking command of the single chip microcomputer can be responded in time through the charging and discharging brake circuit, the brake response of a motor coil is controlled within 1/16 circles, the brake efficiency is high, and the conditions of reverse rotation and unfixed brake response time are avoided.

Description

technical field [0001] The invention relates to the technical field of motor drive, in particular to a speed-regulating and decelerating motor driving device and a driving method implemented by the speed-regulating and decelerating motor driving device. Background technique [0002] Speed-adjusting and decelerating motor drives are generally controlled by analog, which cannot realize automatic intelligent control. [0003] Existing speed-regulating and decelerating motors use a relay switching circuit or a reverse drive to perform braking, and there will be a phenomenon of long braking response time (ie > 1 / 4 turn). In addition, the relay is prone to sparking or high current, resulting in electrocution and oxidation damage, thereby affecting the service life. Regular inspection and replacement are required for normal use, and the use and maintenance costs are high. In addition, reverse rotation occurs and the brake response time is not constant. Contents of the inventi...
