An e-bike sine wave motor controller is a device that converts a DC current into a sine wave AC and supplies it to the motor. Common e-bike sine wave motor controllers include three-phase sine wave controller, single-phase sine wave controller, servo controller and so on. The characteristics of these controllers are as follows:
1. Three-phase sine-wave controller
The three-phase sine wave controller gives three sine waves according to the three-phase coil of the motor, so that the motor gets the sine wave AC supply. The controller is suitable for three-phase coil motors, and can achieve accurate motor control, but the price is high, and it is not suitable for cost-sensitive applications.
2. Single-phase sine-wave controller
A single-phase sine wave controller is similar to a three-phase sine wave controller, but it has only one sine wave output port. The controller is suitable for single-phase motors and low power motors, low price and easy to install, but not for high power motors.
3. Servo controller
Servo controller is a e-bike sine wave motor controller with high precision, which can monitor the speed and position of the motor and control the motor movement according to the data. It can achieve precise motor control, suitable for applications that require high precision motor control, but the price is high.
