Product Introduction

working principle

Control signal input processing: The DC motor drive board performs logical analysis and drive output on the

control signals transmitted from the controller or other command sources through the control chip. The control

signal first passes through a preamplifier, and then undergoes digital logic analysis and processing through a

driver chip, including analyzing the type, execution effect, and other related operation instructions of the control

signal. Finally, it is output to the power output module for control

Output control of power drive module: The processed control signal is sent to the power output module, which

converts electrical energy into mechanical energy and drives the motor to rotate by controlling the driving

components such as MOS or transistor in the output module. Due to the different working principle of the

DC motor drive board from ordinary motors, it is usually necessary to match the signal output by the chip

with the actual drive interface of the motor through an adapter or adapter cable

Acquisition of motor operation feedback signal: In order to better grasp the operation status of the motor

and the problems that occur during the motion process, the drive board is designed with some sensors, such

as Hall sensors, photoelectric sensors, etc., to obtain the motor's motion trajectory, speed, torque, current and

other related parameters. These parameters are output to the drive board for analysis and processing, and if

necessary, the control signal is adjusted to achieve better motor operation performance

Application scenarios

The Siemens C98043-A7020-L4 inverter DC board is widely used in various applications that require precise

control of motor operation, including:

Industrial automation: Used for precise control of motor start, stop, and speed regulation in various

mechanical equipment on the production line.

Household appliances: Used to provide stable motor drive in household appliances such as washing

machines and vacuum cleaners.
