Powerhobby BMA-01 Brushless RC Motor Analyzer RPM KV Voltage Checker (Sensored & Sensorless)

Powerhobby BMA-01 Brushless Motor Analyzer RPM KV Voltage Checker Motolyzer (Sensored & Sensorless) 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 the real-time measuring value of either sensor or sensor-less brushless motor. KV / VOLT / RPM / AMP KV(RPM per Volt) —-Show the rotor RPM/Volt at a certain throttle power level.U(VOLT) —-Show the input voltage to the 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 end bell 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 the air vibrates, it causes compression waves in the air. These waves move away from the motor as sound or noise. The vibration noise of the motor is adverse to the Performance of the 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.
