Product Features
  • Quick response - achieves full speed from motor start in just 0.25 seconds
  • Excellent compatibility and stability with specialized control algorithm for disc motors
  • Synchronous freewheeling technology improves throttle linearity, driving efficiency, and enables automatic energy recovery during motor speed reduction
  • Includes CAN communication interface for real-time communication with flight control (requires compatible flight control system)
Protection Functions
Short Circuit Protection

Automatically shuts down output when detected, then restores operation after 100ms delay.

Stall Protection

Requires throttle return to zero to restore operation after stall detection.

Voltage Protection

Prevents motor start if battery voltage is below 16V or above 64V (disabled during flight).

Temperature Protection

Reduces output power at 125°C, cuts output at 140°C, with gradual power restoration as temperature decreases.

Throttle Loss Protection

Cuts power after 2 seconds of signal loss, with automatic restoration upon signal recovery.

Startup Protection

Shuts down output if motor doesn't start within 10 seconds of throttle increase.

Throttle Calibration

Follow audible cues ("bi bi" and "DO Mi sO" sounds) to successfully set throttle range.
