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.

both brake switch and motor temperature sensor functions at the same time on the latest

version.Pin 25 is 12V brake switch input port.Pin1 is motor temperature sensor input port.

(15) Optional joystick throttle. A bi-symmetrical 0-5V signal for both forward and reversing.

(16) Configurable motor over-temperature detection and protection with the recommended

thermistor KTY84-130 or KTY84-150.

(17) 3 hall position sensor inputs. Open collector, pull up provided.

(18) Enhanced regen brake function. A novel ABS technique provides powerful and smooth

regen.The regen can happen at any speeds until zero speed.

(20) Cruise control.

(21) KLS-D can support Broadcast type CAN Bus function.It is 250Kbps.CAN bus is not

included in KLS-D controller by default.

Caution! The regen is not a safe function.Usually you may use the mechanical brake.

power on.

18) Current multiplication: Take less current from battery, output more current to motor.

19) Easy installation: 3-wire potentiometer will work.

20) Standard PC/Laptop computer to do programming.There is one more choice for customers

to program KLS controller.Standard Tablet with Android OS to do programming.Need a

Z-TEK USB TO RS232 cable for connecting the controller to App program in Tablet.

21) User program provided. Easy to use. No cost to customers.

22) Support motors with any number of poles.

23) Up to 70,000 electric RPM standard. (Electric RPM = mechanical RPM * motor pole

pairs;Motor pole pairs=Motor poles/2).

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.

Notes:

1. All RTN pins are internally connected.

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.
