Overview
HOBBYWING Tunalyzer is a Tool of Motor Testing and Tuning designed to evaluate brushless DC motors and related internal components. It displays real-time data on a color touch screen, including Kv value, RPM, current, end-bell timing, and sensor-related elements. Built-in Bluetooth connectivity supports communication with compatible HOBBYWING ESCs via a mobile app for parameter setting and firmware updating (ESC must support the OTA Bluetooth module).
Key Features
- Measures motor current, Kv value, RPM, end-bell timing/deviation, rotor asymmetry, hall signal deviation, and motor temperature.
- Automatic test mode with accurate current readings within 0.01A; end-bell deviation, rotor asymmetry, and hall signal deviation accuracy within 0.1 degrees.
- Manual test mode for benchtop checks with forward/reverse and 100% linear throttle; live data output is displayed.
- Stable voltage regulator for repeated tests at the same voltage as the battery pack discharges (uses preset voltages; battery must be greater than the set voltage).
- Supports sensored and sensorless brushless motors, including multipolar motor types.
- Motor pole setting supports 2-60 pole motors for real-time RPM display.
- 3 inch color touch screen display.
- Multi-function control dial for throttle control and external testing; PWM output supports bench testing of servos and ESCs.
- Built-in reverse power supply protection circuit to help prevent damage from incorrect battery connection.
- OTA tuning and upgrades: can double as an ESC programmer for benchtop ESC tuning via the HW Link App using Bluetooth.

Manuals
Connection Notes
- Do not connect the battery to the A B C motor interface by mistake, otherwise the device will be damaged.
- When testing a sensored brushless motor, the A, B and C wiring must be connected in strict accordance with the sequence of A-A, B-B and C-C.
- During the test, ensure that the motor A, B and C ends will not touch each other and cause a short circuit, so as to avoid damaging the device.
