Feature: 1. Hall effect sensor test 2. KV, RPM, Voltage, Ampere, Noise Level measurement 3. Current drawn less than 30A at 8.4V without loading 4. Motor timing checking: Average timing, phase A, B, C timing 5. Input voltage: 7.4-8.4V(suggested to use 7.4V 2S LiPo battery) 6. Supported motor: Sensored or sensorless brushless motor(2 Poles to 36 Poles) Specification: SKYRC 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 LCD diaplay screen which can display real time measuring value of either sensored or sensorless brushless motor.
