ABSTRACT
When the DC motor starts, the motor is stationary, the induction potential on the armature is zero, and the motor current rises quickly to produce a large inrush current, which will not only cause damage to the unit equipment but also cause perturbation of the power supply. In addition, in some applications encountered in the motor blocked rotation, electrical energy is fully converted to armature and MOSFET transistor thermal energy, accelerating the aging of the armature enamel wire, reducing the service life of the motor. In order to solve the problem of excessive inrush current when starting and blocking the motor, this paper presents an H-bridge a current-limiting control drive circuit for DC motor start-up and blocking. The circuit designed in this paper adds a current detection circuit to the driving circuit, and uses the parasitic inductance of the motor armature to effectively limit the peak current of the motor through the control of a fixed shutdown time to achieve the current limiting effect. The test results show that the motor can limit the current output during starting and blocking, and the current output is good without affecting the normal operation of the motor.
