This motor analyzer is a precision electronic device that is specially designed for measuring the KV value, RPM, current draw, motor timing, vibration noise level, and function of hall effect sensors of a brushless motor. It comes with a 2X16 character LCD that is able to display real-time values of either sensored or sensorless brushless motors.

KV / VOLT / RPM / AMP:
KV (RPM per Volt) Shows the rotor RPM/Volt at a certain throttle power level.
U (VOLT) Shows the input voltage to the motor checker.
RPM (Revolution Per Minutes) Shows the rotor revolution at a certain throttle power level.
I (AMP) Shows the current drawn by the motor at a certain throttle power level.

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

NOISE LEVEL - Poor assembly, inferior bearings, or unbalanced rotors can generate a vibration. This vibration is adverse to the performance of the motor. By measuring this, you can select the "quietest" motor.

Phase A, B, and C Sensor Timing: Shows the actual timing of all three sensor elements
