Abstract

The invention provides a reversible rotation driving circuit of a control motor and is applicable to the field of electronic lighting. The switching function of the reversible rotation driving circuit of the control motor in the embodiment can be realized by substituting a relay by a switch tube, and the service life of the driving circuit is prolonged by a contactless switch. Meanwhile, the problem about damage of the switch tube caused by pressing a switch S1 and a switch S2 at the same time is solved, reliability of the driving circuit is improved and volume thereof is reduced.

Description

technical field [0001] The invention belongs to the field of motor control, in particular to a drive circuit for controlling the forward and reverse rotation of a motor. Background technique [0002] Motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. [0003] At present, many motor drive circuits on the market are basically controlled by relays. However, due to the large size of relays, it is not conducive to the miniaturization of integrated circuits, and the relays are connected by contacts, so their life will be limited, which will greatly affect the motor drive circuit. reliability. Contents of the invention [0004] The object of the present invention is to provide a driving circuit for controlling the forward and reverse rotation of a motor, aiming ...
