Description
Digital Tube Display PWM DC Motor Governor 12V 24V Motor Control PWM Brush DC Motor Speed Controller Soft Start Switch
Product Description
The digital rotary encoder potentiometer uses the principle of digital pulse. It outputs as much as it turns. It will still output the same value next time it turns back. It has good repeatability and high accuracy, and it can be quickly adjusted to the desired value.
Product Highlights
1. Comes with a start-stop button, and can be controlled by an external switch, to meet customers' various control needs. 2. The motor soft start function, the current slowly increases when the motor is started, there is no impact current, and it effectively protects the motor and prolongs the service life of the motor. 3. You can set the duty cycle, the upper and lower limits of the duty cycle, and the working frequency, which is convenient for customers to operate and use according to the working characteristics of their own motors. 4. The digital encoder knob adjusts the motor speed, which has higher precision and better consistency than ordinary potentiometers. 5. With standard 5135 instrument housing, it is convenient for customers to install.
Why does the motor speed controller need to set the frequency???
The frequency of the motor speed controller is too low, the power supply wave is large, the motor vibration is too high, the frequency is too high, the switching loss is large, and the electromagnetic noise is relatively obvious. If the frequency is not suitable, the effective power output of the motor will be greatly reduced. The factory default frequency of this product is 20KHz, which can meet the requirements of most motors. Reminder: For brushless motors, this governor is not suitable for use.
Why do motor speed controllers use digital encoder knobs instead of ordinary potentiometers???
Temperature changes change resistance Humidity changes change resistance Carbon brush wear changes resistance Vibration changes resistance The number of turns is adjusted and fixed Rotating it to the end and then turning it hard will damage it
