SkyRC Brushless Motor Analyzer

The SKYRC Brushless Motor Analyzer is a precision electronic device designed to measure the KV value, RPM, current drawn, physical endbell timing from 0 to 70 degrees, and vibration noise level from 60 dB to 120 dB of brushless motors. It also checks the function of hall effect sensors and measures individual Phase A, B, and C sensor timing. Equipped with a two-line LCD screen, the analyzer supports both sensored and sensor-less brushless motors from 2 to 36 poles. This compact tool operates on an input voltage of 7.4-8.4 V and displays real-time values with high accuracy, including KV value accuracy of +/- 3% and motor timing accuracy of +/- 4%.

Key features

• kV (RPM per volt): rotor speed per volt at a given throttle setting
• U (voltage): input voltage to the motor analyser
• RPM: rotor speed at a given throttle setting
• I (current): motor current draw at a given throttle setting
• Motor timing: physical endbell timing; rotating the sensor board requires tools
• Noise level: measures motor vibration noise in decibels (dB); poor assembly, bearings or an unbalanced rotor can cause vibration
• Vibration noise adversely affects motor performance; measuring noise levels helps select the less noisy motor
• The decibel (dB) is a logarithmic unit used to express noise level
• Phase A, B and C sensor timing: displays the actual timing of each of the three sensor elements
• Checks the function of Hall effect sensors
• Supports sensored and sensorless brushless motors (2 to 36 poles)
• Two-line LCD screen with blue backlight and white text, 16 characters × 2 lines
• Displays real-time values with high accuracy
• KV value accuracy: ±3%
• Motor timing accuracy: ±4%
• Current drawn without loading: less than 30 A at 8.4 V
• Compact tool
