Square Wave Controller Description

The YYK controller is a square wave high discharge high speed controller. Discharge current rates start from 50A all the way to 150A. And they can accommodate a variety of voltages from 48V to 72V or 100-120V. The YYK is a universal controller which is easy to wire up and to adapt to virtually any e-bike or e-scooter drive train.

Here is how the YYK square wave controller works:

Controller Configuration via Bluetooth App

Here is how to download your YYK app to configure the wide range of parameters to adjust the power, acceleration and speed of your new YYK powered Fiido e-scooter!

Sinewave FOC Controller

Our sinewave FOC controllers are smoother and more efficient without sacrificing the torque and top speed of squarewave controllers. From launch, the sinewave foc controllers will feel more gradual and smooth whereas squarewave versions will feel more torquey and jerky.

We have available the 50A and 70A versions of the sinewave controller.

Specifications

48V-72v, max current 50A/80A/100A high powered brushless motor controller, voltage cutoff value is 42V, is suitable for 48v to 72v battery. Phase angle 120 degree. Install apps to your smart phone and use Bluetooth device available for setting the controller current, voltage, speed and other data.
