- In addition, long life: The motor has no carbon brush. Therefore, it can reduce wear during use.
- Also, low EMI: The driver board helps reduce electrical noise. In addition, this supports stable control.
- Finally, high speed: The motor can run at higher speed. Moreover, users do not need to worry about brush damage.
High Power Brushless Gear Motor Wiring Instruction
Wire Function Guide
First, the wiring guide below explains the wire function. Therefore, users should check each wire before power-on.
In addition, correct polarity can help protect the built-in driver board. As a result, users should never reverse the red and black power wires.
- First, red wire: Connect to the positive pole of the motor power supply. Therefore, do not reverse the polarity.
- In addition, black wire: Connect to the negative pole of the motor power supply. In addition, keep the polarity correct.
- Also, white wire: Use it as the direction control wire. When disconnected, the motor rotates in one direction.
- Next, white wire reverse mode: Connect it to the negative pole with the black wire for reverse rotation.
- Moreover, blue wire: Use it as the PWM speed control wire. Therefore, connect it to a 0-5V pulse width modulator.
- Finally, yellow wire: Use it as the FG signal wire. As a result, it outputs 6 square wave pulses for speed feedback.
PWM Speed Control Mode
First, the blue wire works as the analog or PWM speed control input. However, speed control works only when the PWM frequency stays within 15 – 35kHz.
Therefore, if the frequency does not match this range, the motor may not regulate speed correctly. In addition, users should check the wiring or use a PWM signal with the correct frequency range.
- First, PWM frequency range: 15 – 35kHz.
- In addition, 0 – 1V input: About 0% – 20% speed.
- Finally, 3.3 – 5V input: About 75% – 100% speed.
Motor Terminations
First, the table below shows the motor termination data. In addition, it helps users confirm voltage, FG signal, speed input, and direction control.
Therefore, users can use this data to check GND, Vcc, FG, speed input, and CW/CCW logic before testing the motor.
