If you are planning to build your own electric bike or upgrade a current one, then knowing how to wire the controller is important. The controller is the brain of the electric bike and it determines how fast and how far your bike can go. In this article, we will provide you with a comprehensive 36-volt e-bike controller wiring diagram to help you wire your own controller.
To begin with, let’s take a quick look at the basic components of an e-bike controller. The controller consists of three main wires – red, green, and black. The red wire is for power, the green wire is for the throttling signal, and the black wire is for the ground. Apart from these three wires, there are other wires that are connected to different components of the e-bike, like the throttle, battery, motor, and brake lever.
When it comes to wiring the 36-volt e-bike controller, it’s important to follow the wiring diagram to avoid any electrical issues during the operation of the bike. To begin with, connect the red wire to the positive terminal of the battery and the black wire to the negative terminal of the battery.
Next, locate the three-phase wires coming from the motor and connect them to the three-wire phase connectors of the controller. Typically, the motor wires will be white, black, and red. Connect the white wire to the white phase connector on the controller, the black wire to the black phase connector on the controller, and the red wire to the red phase connector on the controller.
Now, it’s time to connect the throttle to the controller. Identify the three wires coming from the throttle. Typically, the throttle wires will be green, black, and red. Connect the green wire from the throttle to the green wire on the controller or the wire that’s labeled as throttle, connect the red wire from the throttle to the red wire on the controller or the wire that’s labeled as +5v or 5v, and connect the black wire from the throttle to the black wire on the controller or the wire that’s labeled as ground.
Next, connect the brake lever to the controller. Typically, the brake lever wires will be red and black. Connect the red wire from the brake lever to the wire on the controller that’s labeled as brake or brake signal, and connect the black wire from the brake lever to the black wire on the controller or the wire that’s labeled as ground.
Finally, connect the power wires to the respective terminals on the controller. Typically, the power wires will be red and black. Connect the red wire to the terminal that’s labeled as + or Vcc, and connect the black wire to the terminal that’s labeled as – or Gnd.
By following the 36-volt e-bike controller wiring diagram mentioned above, you can wire your own e-bike controller with ease. However, it’s important to note that if you are not confident in your ability to wire the controller yourself, it’s best to seek help from a professional.
