Abstract

The invention relates to a motor driving module, which comprises a pulse circuit, an input circuit, a PWM circuit, a power driving protection circuit and a power switch driving circuit, wherein the input circuit is connected with external signal input equipment; the PWM circuit is electrically connected with the pulse circuit and the input protection circuit respectively; the power driving protection circuit is electrically connected with the PWM circuit; and the power switch driving circuit is electrically connected with the power driving protection circuit. The pulse circuit can generate oscillation and only has two transient steady states, the pulse circuit generates oscillation signals, so that the oscillation signals do not need to be input from external equipment, the input protection circuit and the power protection circuit can prevent overlarge current, a circuit protection effect is achieved, and the safety performance is improved.

Description

technical field [0001] The present invention relates to the technical field of motor modules, in particular to a motor drive module. Background technique [0002] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. With the continuous progress and development of society, the motor has been integrated into various fields of human life. The motor can be divided into DC motor and AC motor. It can be divided into single-phase motors and three-phase motors, and motors are commonly used in power tools, furniture, and transportation equipment. [0003] Among the existing motors, many motors work in harsh environments, especially in the military industry, which need to adapt to special environments, such as high temperature and high pressure or humid environments. Long-term harsh environments cause the drive modules in the motors to be easily damaged. [0004] For example, the util...
