SKYRC BL Motor Analyzer


Motor Analyzer

SKYRC motor analyzer is a precision electronic device that is Specially designed for measuring the KV value, RPM, 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.

KV Measurement Voltage Measurement RPM Measurement Amperage Measurement Motor Timing Checking Noise Level Hall Effect Sensor Test
Hall Effect Sensor LED Throttle Level LED Indicators Rotary Dial


KV(RPM per Volt) ----Show the rotor RPM/Volt at a certain throttle power level.
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.

Average Motor Timing

MOTOR TIMING ----Physical endbell timing, usually between 0 and 70 degrees, requires tools to rotate the sensor board.

Noise Level

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 measuring 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.

Phase A, B and C Sensor Timing

Phase A, B and C Sensor Timing: Show the actual timing of three sensor elements as above picture.
