567LH-DP24 REOTRON Drive module robot

Product details:

Driver is the controller that drives the robot power mechanism to complete the action. It is also one of the four core components of the robot ontology hardware. If you think of the links and joints as the bones of a robot, then the actuators act as muscles. According to the different power source, the driver is divided into “motor driver”, “hydraulic driver” and “pneumatic driver” three categories. But in the world of robots, it’s generally the “motor driver” that rules the roost.

When a robot is moving, it usually needs to control its torque, speed and position. And these, all rely on the motor control system to achieve.

A motor control system, including motor, MCU, drive circuit, signal conditioning circuit four major hardware. In a broad sense, all parts other than the motor belong to the motor driver.

And the motor also needs to be in coordination with the driver to really move. Without the driver, the motor would stop working and the robot would collapse.

1. The DC brushless motor replaces the mechanical commutator with the electronic commutator. Because of the electronic commutation, the DC brushless motor needs to use the driver drive circuit.

2. If the stepper motor wants to run, it must input pulse. If there is no pulse, the stepper motor is stationary, so we need a driver to energize the windings of the stepper motor in turn.

3, the servo motor is no brush and commutator, so to maintain the direction of rotation, there must be an electronic commutator. The electronic commutator is controlled by the driver. At the same time, the servo controller can also control the start and stop of the motor, positive and negative rotation, speed regulation, over-voltage, over-current and under-voltage protection. So you have to have a servo drive, even if you put the servo motor directly on the power will not work.

Therefore, different drivers have different functions, and what they have in common is more accurate control of the motor.
