Can the sine wave controller solve the problems of noise and jerking in electric vehicles?
Currently, the controllers of most electric vehicles have the drawbacks of high motor noise and strong running jerking caused by square wave control. Users have long suffered from poor riding experience and rapid motor wear. We have innovatively developed a sine wave brushless motor controller that adopts SVPWM space vector modulation technology, achieving full voltage adaptive control of 48V/60V/72V, reducing the motor noise to below 45 decibels. The actual measurement data of a logistics company shows that the motor temperature rise of the vehicles equipped with this Electric Tricycle Control Device has decreased by 40%, and the range has increased by 18%, which is particularly suitable for high-load transportation scenarios requiring a Dual Drive Motor Controller.
