DDBLDV1.0 Brushless DC motor Driver
1、Introduction
DDBLDV1.0 is a High performance BL motor Driver with the chip SCM1243MF of
SANKEN inside. It appropriate to driver little and middle power Brushless DC motor.
The most power is 750W. To driver the same motor, this driver can make more speed
and more power to motor. It’s control method is sample and reliable.
2、Specification
■High performance, low price
■Three-phase intelligent driver chip
■Supply voltage24~60VDC
■Input electrical signal TTL compatibility
■No current when static
■easy to install
■The most power is 750W
■There are 3 methord of speed control, regulation resistance inside、voltage
signal 、PWM signal
■Drive BL motor the most rotation to 12000r/min
■There is speed port, it’s easy to measure the rotation of BL motor.
■There are overvoltage 、 overcurrent and lock rotor test inside.
■There is IPM chip SCM1243MF inside, It’s more stabilize than MOSFET.

5、wire connection definition
Control port（MACHINE CONTROL）
信号 功能
FG Motor speed feedback signal, each pulse indicate half circle
DIR Motor direction signal +. When DIR=5V, the BL motor is counter-clockwise
（observe from the tail of motor）.When DIR=0V, the BL motor is clockwise
（observe from the tail of motor）.This signal is High level(5V) when it’s not
connect.
EN Enable +.When EN=5V, the driver is invalid and when EN=0V,the driver is
available
GND General Ground，FG\DIR\EN\VE signal should control refer to GND
VE Motor Speed control port, you can give a 0-5V voltage signal to this port in
voltage mode. Or give a PWM signal(5~8Vpp)to this port in PWM mode.
5V This is 5V output reference port，When you want to control motor speed with
regulation resistance .5V port can be used as high voltage reference port.
Please don’t supply 5V power to this port.
HALL PORT(BL DC motor)
signal function
HW Hall signal of W port
HV Hall signal of V port
HU Hall signal of U port
H+ Power output port + for Hall
H- Power output GND for Hall

Power port
signal function
G Shell port. This port is connect to Shell of the product. You can connect it to
the main box shell.
+48V Main power+，The voltage of power should be in 24V-60VDC，48V is
recommend
GND Power Ground.
W W port of BL DC motor
V V port of BL DC motor
U U port of BL DC motor
CAUTION: This driver do not contain the anti-plug backward circuit, thus
positive-negative reversal is prohibited! Otherwise, the driver will be damaged

9、power supply
Machine could operate within the voltage of DC24V-60V. The common switch DC power supply
and the transformer+bridge rectifier+capacitor filtering (capacitance range:2000U-5000U), both are
allowable for the DDBLDV1.0 driver’s power supply. But the voltage wave crest shall less than 50V. It is
recommended that the user adopt the 36V-48V DC power supply lest the power grid fluctuation exceeds
the driver’s voltage range.

RESIN RES inside ON OFF OFF
RESO RES or voltage outside OFF ON OFF
PWM PWM signal OFF OFF ON
LED description instruction
红色 LED Power LED This LED should light when power supply in, and
also should light out when power cut off.
绿色 LED Error LED This is locked rotor indicated LED. When the BL
DC motor is locked rotor, this LED will light.
Attention,Sometimes this LED will light when
motor is stop in control.You can ignore it ,or restart
the power of DDBLDV1.

Change speed by PWM signal outside
12、Matching with motor
DDBLDV1.0 Driver can driver most of BLDC motor below 60V 750W,which with HALL or without
HALL. To make it work fine, you should choose the correct voltage.
