Outer Rotor Design BL5520 Electric Motor Capable of Operating on a Voltage of 24V DC While Supporting Variable For PWM Speeds Features: Model: BL5520 Rated voltage: DC24V Rated power: 40w (approximately) Wire length: about 7mm Weight: 165g Idle parameters under various voltages: Voltage: DC12V No-load current: 0.16 A No-load speed: 2040 RPM Voltage: DC18V No-load current: 0.19 A No-load speed: 3050 RPM Voltage: DC24V No-load current: 0.21 A No-load speed: 4070 RPM The wiring definition is as follows: Red line: positive pole Green line: FG ( signal line, suspended without wiring) Yellow line: direction line, connect to the negative pole to change direction Black line: GND common terminal (power supply negative pole + for PWM negative pole) Blue line: for PWM (connect to the negative pole and the motor will run at the highest speed) The yellow line is the direction line. When the yellow line is connected to the black line, the motor rotates in the CW direction. When the for PWM signal is input, the motor rotates in the CW direction. , we adjust the frequency of the pulse signal to about 3000Hz, and adjust the duty cycle to 0%-90% to adjust the speed. Wiring way : If the work is simple, connect the red wire to the positive pole, the black wire and the blue wire to the negative pole, and the motor starts working directly. If speed adjustment is required, connect the red wire to the positive pole, the black wire to the negative pole, and the blue wire to for PWM . Note: The brushless DC motor comes with a driver board. It is strictly forbidden to connect the positive and negative poles in reverse. The red wire should be connected to the positive pole and the black wire should be connected to the negative pole. If the positive and negative poles are connected in reverse, the driver board will be burned.
