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.
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. KLS 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.
KLS-8080N/NPS is designed by opto-isolated technology. We specify 8-20V for
power supply which must be isolated from main battery pack B+/B-.You may use an
isolated DCDC converter or a separate 12V battery for power supply.KLS-8080N is
supposed to work with BLDC motor with hall sensors. KLS-8080NPS can work with
brushless motor with Sin/Cosin speed sensors.
KLS-8080N/NPS controllers include the fuse on the plastic case.
Anyway please try to do identification angle operation before running the motor.
