Abstract

The invention provides a motor driving device and system. The motor driving device comprises a driving module, a boosting module and a level isolation module. The boosting module is electrically connected with the driving module to provide voltage undergoing boost processing to the driving module. The level isolation module is electrically connected with the driving module to provide a level signal undergoing isolation processing to the driving module. The driving module is electrically connected with a motor so as to drive the motor to work. Therefore, the motor drive device provided in the scheme has strong overcurrent capacity, and the motor driving device has the advantages of being not likely to produce heat, high in reliability, strong in driving capability and the like. In addition, circuit functions of the motor drive device provided in the scheme can be also decreased or increased according to the actual demand.

Description

technical field [0001] The invention relates to the technical field of bicycle robot drive, in particular to a motor drive device and system. Background technique [0002] With the continuous development of science and technology, the application of intelligent control has become more and more extensive, and has penetrated into almost all fields. Among them, smart car technology relies on intelligent control and has broad development prospects. [0003] The motor drive design of the smart car should meet the design requirements of being able to control the forward and reverse rotation of the motor and adjust the speed. In the prior art, an integrated motor driver chip (such as an integrated H-bridge motor driver chip) is often used. Although this integrated chip has a simple circuit structure and good stability, the chip has poor overcurrent capability and poor heat dissipation. Well, it gets hot easily, has weak actuation ability, and costs more. Contents of the inventi...
