Company Profile

Dongguan Yunli Electronic Technology Co., Ltd. is a technology innovation enterprise that focuses on the research and development, manufacturing, and sales of motor drives.

Our company specializes in the research, production, and sales of sine wave controllers and their accessories.

Sinewave controllers are widely used in various applications due to their mature technology and effectiveness as a controller mode.

The Yunli controller, developed independently by our company, is based on the space vector frequency conversion control algorithm.

It boasts high conversion efficiency, effectively reduces the temperature rise of the controller, extends battery life, resolves jitter and instability during vehicle startup,

and offers superior linearity, high starting torque, and efficiency.

Yunli controllers are renowned for their high power and operate in full torque mode, maintaining constant torque while adjusting current output through throttle handle manipulation.

The controller ensures smooth and powerful vehicle starts through linear tuning.

Unlike traditional controllers with excessively fast acceleration speeds, our controllers strike a balance between comfort and power.

The chip utilized is a powerful 32-bit MCU from a reputable brand, ensuring faster processing speeds.

Customized MOSFET circuit layout and the use of heat dissipation materials facilitate rapid heat dissipation, supporting the output of larger currents.

The controller's aluminum housing not only provides a metallic aesthetic but also enhances heat conduction efficiency.
