Miniature Geared Electric Motors Outline Drawing ☑️ Brushless Internal Hall Driver Board Benefits: High Efficiency / Longevity / Low EMI / High Speed Operation (operate at higher speeds without the risk of brush wear or damage) High Power Brushless Gear Motor Wiring Instruction 【Red Wire】Positive pole of motor power supply , polarity must not be reversed. 【Black Wire】Negative pole of motor power supply -, polarity must not be reversed. 【White Wire】Direction control wire, when disconnected, the motor rotates in one direction; connect to negative pole along with black wire for reversing. 【Blue Wire】PWM speed control wire, connect to a 0~5V pulse width modulator. 【Yellow Wire】FG signal wire, outputs 6 square wave pulses. Speed can be determined by detecting the frequency of the pulses (similar to a single-wire encoder). PWM Speed Control Mode: – PWM frequency range: 15 – 35kHz – 0 – 1V corresponds to approximately 0% – 20% speed – 3.3 – 5V corresponds to approximately 75% – 100% speed The blue wire is the analog/PWM speed control input. Speed regulation is only effective when the PWM frequency is within 15 – 35kHz. The frequency you are using does not match this requirement. Please check the wiring or use a PWM signal with the correct frequency range for proper speed control.
