Thank you for purchasing the Motor Checker BMC-01. We are confident you will find it
to be an indispensable tools you use to make your hobby more funs and enjoyable.
Brushless motors are the most popular motor choice now in the RC Car and model
aircraft industry. With their superior power to weight ratios, a large range of sizes,
from under 5 grams to large motors rated at thousands of watts, they have
revolutionized the market for electric-powered model field.
Their introduction has redefined performance in electric model aircraft and helicopters,
displacing most brushed and internal combustion power sources. The large power to
weight ratio of modern batteries and brushless motors allows models to ascend
vertically, rather than climb gradually. The silence and lack of mess compared to
small (glow engines) internal combustion engines that were used is another reason
for their popularity.
Motor Checker is a very sophisticated electronic device. It has three main functions:
1. Brushless Motor Checking (Both Sensor & Sensor-less)
KV Measurement(Accuracy tolerance 5%)
RPM Measurement
Ampere Measurement (Current Drawn by Testing Motor up to 18A)
2. Hall Effect Sensors Test
Brushless Motor with Sensors Only
3. Motor/Car Diff Break-in

In order to measure the RPM and KV value correctly, you need to select the magnet
poles number according to the motor you are testing. The default values of this motor
checker for Car Motors are 2 poles and Flight Motors are 6 poles.
For magnet poles other than 2 or 6, you can still measure the RPM and KV value.
Measure the KV value under Car Motor (2 magnet poles) and using simple formula
to find the actual RPM and KV value.
Hall Effect
Sensors Indicator
Actual KV Value of n poles = KV Value under 2 poles / (no. of poles / 2)
n=2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24
Throttle Level Indicator
For example, for 8 magnet poles motor, KV reading under 2 poles is 8000.
The actual KV value of 8 magnet poles motor= 8000 / (8/2) = 2000

KV (RPM per Volt) Show the rotor RPM/Volt at a certain throttle power level.
The KV rating of brushless motor is the constant relating the motors unloaded
RPM to the peak voltage on the wires connected to the coils (the "back-EMF").
For example, a 6,350 KV motor, supplied with 7.6 V, will run at a nominal
48,260 rpm.
I (Ampere) Show the current drawn by the motor at a certain throttle power level.

The above picture shows the throttle power level is enclosed by a dot outline. In order
to prevent from giving a max power to the motor from the start up, the default power
level is 3 for every time to start running the motor. The maximum throttle power level
is 8 and the minimum throttle power level is 1.
V=7.1V RPM=19415
I=0.5V KV =27 34

After power up the unit and press the START key, it will enter to the motor test mode
and motor will start running. As the motor is running, the corresponding parameters
will be measured and shown on the display screen.
At the start of motor running, the default throttle power level is 3. The Inc and Dec key
can be used to increase or decrease the throttle power level.
(a)Connect Motor Checker to 7.6V-8.6V power source, the screen will be light up
and display will show the input Voltage, Ampere, RPM and KV values.
When the STOP key is pressed, the motor will stop running immediately and the last
data measured by motor checker will be recorded and kept on the display screen.
(b)For sensor type motor, connect A, B, C wire cable from motor checker to motor A,
B, C connector. Please make sure the wires should be connected properly before
starting operation.
Wire A: Blue Color
Wire B: Yellow Color
Wire C: Orange Color
2.Hall Effect Sensor Test Mode (Brushless Motor with Sensor Only)
Sensored-type (motors with an extra six wires harness, connected to Hall Effect
Sensors). Hall sensors are commonly used to time the speed of wheels and shafts,
such as for internal combustion engine ignition timing or tachometers. They are used
in brushless DC electric motors to detect the position of the permanent magnet.
After power up the motor checker or after the STOP key is pressed to stop the motor
running, it will enter to the Hall Effect Sensor Test mode automatically. If the motor
sensor harness is connect to the sensor connector of the unit, one or two of the sensor
LEDs will be light up that show the corresponding sensors are function correctly.
There are 3 operation modes: Brushless Motor Checking, Hall Effect Sensor Test
and Motor/Car Diff Break-in.
1. Brushless Motor Checking Mode
The descriptions of each parameter are explained below:
Rotate the rotor for a step, and then the light up sensor LED will be changed. For
example, if the sensor A LED is light up, after the rotor is rotated by a step, then the
sensor A and B LEDs will be fight up at the same time. If rotating the rotor by a step
again, sensor A LED will be light off and sensor B LED will be light up only.
For a proper sensor operation, LED should be light up according to the below sequence:
Please read the Instruction Manual before starting to operate the motor checker.
For those users that do not have experience to use it, please seek help from the
professional users.
Please make sure the voltage apply to the unit is within the required range.
(7.6V 8.6V) and polarity should be connected properly. If the input power polarity is
reversed, the unit may be burnt out.
LED A -> LED A,B -> LED B -> LED B,C -> LED C -> LED C,A -> this sequence will be
repeated if the hall effect sensors are functioned properly.
The following phenomenons that show the motor Hall Effect Sensor do not work properly.
-The LED light up sequence is not correct
-All LEDs light up at the same time
-All LEDs light off at the same time
3.Motor/Car Diff Break-in Mode
The diff break-in function can quickly and effectively break-in your new ball differential.
Simply connect the motor checker to your car's brushless motor directly and holding
the tire on one side only and run break in program. After the break in process is
completed the diff will be smoother and have increased life and efficiency.
After power on the motor checker, press and hold the MODE key for 2 seconds, then
it will enter to the Motor Break-in mode. In this mode, the display screen will be
changed as shown in below.
For some high KV motor, long time no loading working is not suggested.
Motor and this unit will generate heat during operation.
When the message MOTOR DISCONNECTED is appeared, please check and
reconnect the sensor cable and A, B, C motor wires to the unit again.
Make sure A, B, C motor wires are connected to the corresponding A, B, C socket
on the unit. If the error message still appeared, the tested motor may be failure.
It means there is a short circuit on A, B, C connector or
current drawn by motor that is larger than 18A. Please make sure there is no short
circuit of A, B, C connector or the current drawn by tested motor is within the
specification of this unit.
We guarantee this product to be free of manufacturing and assembly defects for a
period of one year from the time of purchase. The warranty only applies to material
or operational defects, which are present at t he time of purchase. During that period,
we will repair or replace free of service charge for products deemed defective due to
those causes.
V (Voltage) input voltage to the motor, the adjustable range is from 2.5V to 7.2V.
T (High to Low Voltage Ratio Step) the adjustable step range is from 1 to 10. If the
step is set to 1, then the break-in hi-low speed is faster. On the other hand, if the step
is set to 10, then the break-in hi-low speed is slower. When the step is set to F, it will
set a fix selected voltage to break-in motor.
RPM (Revolution per Minutes) show the rotor revolution at a selected input voltage.
I (Ampere) show the current drawn by the motor at a selected input voltage.
You will be required to produce proof of purchase (invoice or receipt). This warranty
is not valid for any damage or subsequent damage arising as a result of misuse,
modification or as a result of failure to observe the procedures outlined in this manual.
In Motor Break-in mode, the voltage value V will be flashing for setting. This value can
be set to different values through INC and DEC key.
After the voltage value V is set, press STOP key to change the setting of T value. As
the T value is flashing, the value can be altered through INC and DEC key. When T is
set at 1 and pressing the DEC key again, T value will become 'F' that will fix selected
voltage to break-in the motor.
When both setting are confirmed, the motor break-in process can be activated by
pressing the START key. To stop the motor break-in process, just press the STOP
key to stop it.
To quit Motor Break-in mode, just press and hold MODE key for around 2 second.
