Specification: [vS] Red line, drive voltage, DC+310V (220V AC is 310V DC after connected to the rectifier bridge, and it is better to add a 100uf/400V filter capacitor). This time, the wide voltage of the motor is DC176V-375V, that is, it can be used after rectified with AC 110V-220V. [GND] Black wire, the negative pole of all power supplies are connected together. [Vcc] White wire, working voltage, DC14-16V [Vsp] Yellow line, speed control, 0-6.5VPWM speed regulation, the lower the voltage The slower the speed, the better the mediation [FG] Blue line, speed feedback [Note]: This motor is a 220V motor. It does not generate 220V power. The following is a picture of power generation. It is simpler to generate power: connect the red and black wires. Both the positive and negative rotation can generate power. With LED lights, you do not need to connect anything. With others, you need to rectify and stabilize the voltage. DIY is made by yourself Power generation is the generation of direct current Approximate power generation parameters: 120 rpm: 9v 240 rpm: 18V 480 rpm: 36V 960 rpm: 72V Product includes: 1 x Brushless Generator
