BRUSHLESS MOTOR ANALYZER

Thank you for purchasing the Motor Analyzer BMA-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.

The motor analyzer is a precision electronic device that is especially designed for measuring the KV

value, RMP, current drawn, motor timing, vibration noise level and checking the function of hall effect

sensors of a brushless motor. It comes with a 2X16 characters LCD that is able to display real time

measuring value of either sensor or sensor-less brushless motor.

Please read the Instruction Manual before starting to operate the motor analyzer. 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. (7.4V-8.4V) and polarity

should be connected properly.

IF THE INPUT POWER POLARITY IS REVERSED, THE UNIT MAY BE BURNT OUT.

For some high KV motor, long time no loading working is not suggested.

Motor and this unit will generate heat during operation.

SAFETY PRECAUTIONS

When the message RUN ERROR 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. And please make sure there is no short circuit of A, B, C connector. If the error

message still appeared, the tested motor may be failure.

APPLICATIONS

1. KV / VOLT / RPM / AMP

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 6,768 KV motor, supplied with 7.9 V, will run

at a nominal 53,468 rpm.

U(VOLT) Show the input voltage to motor checker.

RPM(Revolution Per Minutes) Show the rotor revolution at a certain throttle power level.

I(AMP) Show the current drawn by the motor at a certain throttle power level.

2. MOTOR TIMING

MOTOR TIMING: Physical endbell timing, usually between 0 and 70 degrees, requires tools to

rotate the sensor board.

NOISE LEVEL: Poor assembly motor, inferior bearing and unbalanced rotor can generate a vibration.

Whenever a motor in air vibrates, it causes compression waves in the air. These waves move away from

the motor as sound or noise.

Vibration noise of motor is adverse the performance of motor. By measure the noise level of motors, you

can select the less noise motor.

The decibel (dB) is a logarithmic unit used to express noise level in this motor analyzer.

4. HALL EFFECT SENSOR TEST (BRUSHLESS MOTOR WITH SENSOR ONLY)

For a proper sensor operation LED should be light up according to the below sequence, :

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

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 analyzer 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.

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.

Average Motor Timing

The performance of the motor is not only related to the endbell timing. It also depend on alignment and

quality of internal parts such as sensor board and rotor.

Above picture show the actual timing of three sensor elements. This feature shows and measures the

quality of your motor's sensor. Ideally, when the setting of timing on your is 30°, you want the three sensor

elements connected to A, B and C leads to shown exactly same number of degrees. However it is very

difficult to get the same reading in reality world. All manufacturers have variance in the production of

sensors. The values of each A, B and C sensor depends on production batch and how well the sensor chip

is aligned on the PCB. And the distance between sensor and rotor can affect the reading also.

Smaller difference between these values makes a good sensor board.

The Motor Analyzer may not show the same K/V value and Degree of Timing as the manufacturer claims.

The K/V value and Degree of Timing are dependent of many things related to the conditions under which

the motor is running. Motor Analyzer run all motors under the same working conditions and make it easier

to compare between brands and setups.
