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.
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-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.

Chapter 2 Features and Specifications
2.1 General functions
(1) Extended fault detection and protection. Customers can read the error code in PC software
or Android Tablet also.
(2) Monitoring battery voltage. It will stop driving if the battery voltage is too high and it will
progressively cut back motor drive power as battery voltage drops until it cuts out
altogether at the preset “Low Battery Voltage”setting.
(3) Built-in current loop and over current protection.
(4) Configurable motor temperature protection range.
(5) Current cutback at low temperature and high temperature to protect battery and controller.
The current begins to ramp down at 90℃case temperature, shutting down at 100℃.

Chapter 3 Wiring and Installation
3.1 Mounting the Controller
The controller can be oriented in any position which should be as clean and dry as possible,
and if necessary, shielded with a cover to protect it from water and contaminants.
To ensure full rated output power, the controller should be fastened to a clean, flat metal
surface with four screws. Applying silicon grease or some other thermal conductive material to
contact surface will enhance thermal performance.
Proper heat sinking and airflow are vital to achieve the full power capability of the controller.
The case outline and mounting holes’ dimensions are shown in Figure 1.

2. Meter function is to copy either of hall sensors.
3. Switch to 12V is active. Open switch is inactive.
Caution:
•Do not apply power until you are certain the controller wiring is correct and has been
double checked. Wiring faults will damage the controller.
•Ensure that the B- wiring is securely and properly connected before applying power.
•The preferred connection of the system contactor or circuit breaker is in series with the B+
line.
•All contactors or circuit breakers in the B+ line must have precharge resistors across their
contacts. Lack of even one of these precharge resistors may severely damage the controller
at switch-on.
