Press Brake

For sheet metal bending, the press brake is a necessary machine. We have NC type and CNC type press brakes. At the same time, we can customize the punches and dies according to your practical use in sheet metal fabrication.

Shearing Machine

For the straight cutting of steel plate, hydraulic shearing machine is a good choice. It not only has high cutting efficiency, but also requires less investment. We have both swing beam shears and guillotine shears for your selection.

Laser Cutting Machine

In the current metal plate and pipe cutting, laser cutting machine is undoubtedly the best choice. It can not only cut various shapes, but also has small cutting gap, high precision and high cutting efficiency. Today, it is very cost-effective.

What Is a Motor Controller And The Difference Between Motor Controller And Driver

The motor controller is an integrated circuit that controls the motor to work according to the set direction, speed, angle and response time through active work.

Next, explain what is the difference between motor controller and motor controller and driver.

1. What is a motor controller

The motor controller is an integrated circuit that controls the motor to work according to the set direction, speed, angle and response time through active work.

In the electric vehicle, the function of the motor controller is to convert the electric energy stored in the power battery into the electric energy required to drive the motor according to the instructions of gear, throttle and braking, so as to control the driving state of the electric vehicle, such as start-up and operation, forward and backward speed and climbing force, or help the electric vehicle brake and store part of the braking energy in the power battery. It is one of the key parts of electric vehicles.

CNC programmable stepper motor controller can form a perfect stepper motor control system with stepper motor driver and stepper motor, which can control the time-sharing operation of three stepper motors.

The controller adopts computer programming language and has a variety of instructions such as input, output and counting.

It has the characteristics of flexible programming and wide adaptability and can be widely used in various control automation fields.

2. Difference between motor controller and driver

1) Different subjects


It refers to the master command device that controls the start, speed regulation, braking and reverse of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to the predetermined sequence.

Stepper motor driver:

It is an actuator that converts electric pulse into angular displacement.

2) Different characteristics


It is composed of program counter, instruction register, instruction decoder, timing generator and operation controller.

It is the “decision-making body” to issue commands, that is, to coordinate and command the operation of the whole computer system.

Stepper motor driver:

When the stepping driver receives a pulse signal, it drives the stepping motor to rotate a fixed angle (called “step angle”) in the set direction. The rotation runs step by step at a fixed angle.

motor driver

3) Different principles


Electromagnetic suction cup controller: the AC voltage is 380V, reduced by the transformer, rectified by the rectifier into 110V DC, and then enters the suction cup through the control device. At this time, the suction cup is magnetized, and the reverse voltage line is connected during demagnetization. The controller achieves the demagnetization function.

Stepper motor driver:

The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning;

At the same time, the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation and positioning.
