This 25amp KT controller will boost your bike to the next level of performance and you'll gain more power, acceleration and torque for climbing hills. The motor plug has 9 pin holes compatible to the 350w & 500w Bafang rear hub motor. This controller has the HIGO waterproof connectors that are plug and play to the Sondors bikes. Our most powerful 35a KT controller with HIGO connectors is plug and play to the Sondors e-bike. The motor plug will fit our 750w Bafang rear hub motor and 1500w direct drive kit. All of our 35a controllers will have a male XT90-S discharge connector for our L series battery plug.
Jul 28, 2017 · Inside the controller is a circuit board that through sensors and firmware manages voltage and ampage input and output and controls all of the critical functions of your E-Bike.
Each channel of the IC includes a P-I controller with programmable gain values KP and KI. Implementing the control law in the current control device can result in improved performance compared to a software implementation, and can reduce the performance requirements of the microcontroller. Nov 11, 2011 · The torque constant, Kt, of a motor is a very useful parameter for sizing and controlling motors showing a linear speed / torque relationship. Both DC brush type and Brushless motors exhibit this linear performance curve relationship. Without getting into theoretical detail, Kt is simply the slope of the torque / current curve of a motor.
It is sine wave controller with torque simulation function. The controller is suitable for sensored motor only, please be noted. If you want a colorful display, you can choose LCD1, LCD3, LCD5, LCD6(coming soon), LCD7U, LCD8S or LCD8H. If you need LED meter, you can consider KT-890 LED or KT-900S LED meter. Consider the DC motor control system with rate (tachometer) feedback shown in Fig.(a). (a) Find values for K′ and so that the system of Fig.(b) has the same transfer function as the system of Fig.(a). (b) Determine the system type with respect to tracking θr and compute the system Kv in terms of parameter K′ and .
