1 Introduction
1.1 Overview
The biggest difference is KLS-N is a waterproof type controller by default. It is IP66 rating.
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.
Kelly
’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-N motor
controller must be based on hall sensors type. KLS-N 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 can 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. Customers
can connect the KLS controller to Android App in Android Phone if they order Bluetooth
converter from Kelly Controls.
KLS-N has a friendly I/O terminals for customers to hook up the batteries and motor easily.
Anyway please try to do identification angle operation before running the motor.
And please don't try to connect the controller to user program while the motor is still running, let
alone change the setting in user program or Android App. That is to say, if you want to connect
controller to user program or try to do programming, please stop the motor first.
This is the most important thing.
