FAQ

What are the three control modes of servo motor controller?

They are speed control mode, torque control mode and position control mode. Among them, speed control and torque control are controlled by analog quantity, and position control is controlled by pulse. According to the customer’s needs, choose among these three control modes. ... + Read more

What will the poor layout of the motor controller chip cause?

As we all know, poor layout can lead to poor EMI performance, poor heat dissipation, or motor controller equipment can not work normally sometimes. Most of the problems that cause the motor controller to fail to operate normally are caused by poor layout. HF- Motion in the process of independent research and develo ... + Read more

Would the motor controller power supply module and control module be isolated?

It is not necessary to isolate; the isolation is for safety and control performance. So it also depends on your voltage power level, PCB design and product control accuracy requirements. ... + Read more

The Effect of Hall Sensor on Motor Controller

Usually motors are equipped with Hall sensors or encoders with higher precision. This time we will start with Hall sensors with higher universality. Hall sensors are generally distributed inside the motor at an angle of 120 degrees. According to different changes of hall voltage, thus detecting the position of the ... + Read more
