Chapter 1 Introduction
1.1 Overview
This manual introduces the Kelly sinusoidal wave brushless BLDC motor controllers’
features, their installation and their maintenance. Read the manual carefully and thoroughly
before using the controller. If you have any questions, please contact the support center of Kelly
Controls, LLC.

’
s programmable motor controllers provide efficient, smooth and quiet controls for
electric motorcycles, golf carts and go-carts, as well as industrial motor control. It is mainly
supposed to solve noise problems of BLDC motor driving application. The KLS-D motor
controller must be based on hall sensors type.KLS-D controller can not support sensorless
brushess motor for now.Compared to the traditional trapezoidal waveform control technology,
this technique based on sinusoidal wave driving technology to reduce the operation noise and
1/3 switching loss, which well meets the noise reduction and efficiency requirements in the
application of DC brushless motor. It uses high power MOSFET
’
s and, SVPWM and FOC to
achieve efficiencies of up to 99% in most cases. A powerful microprocessor brings in
comprehensive and precise control to the controllers. It also allows users to adjust parameters,
conduct tests, and obtain diagnostic information quickly and easily.People can program the KLS
controller on PC software and Android App.There is one more choice for customers to program
KLS controller now.The APP software is based on Tablet with Android OS.Customers may add a
Z-TEK USB to RS232 cable for programming KLS controller if they want to use Android Tablet.
Both PC software and Android APP can provide one screen to monitor the controller
parameters.Sometimes people can use a small Android Tablet as display device.
KLS-D has a friendly I/O terminals for customers to hook up the batteries and motor easily.
