Overview
MAD ENCR V105 eVTOL Autocenter motor combo is an electronic feathering propeller propulsion system combo with motor + ESC + propeller. The motor uses a magnetic encoder for positioning to detect propeller position when stopped, allowing the blades to stop at a specified position to reduce drag and improve fixed-wing endurance in fixed-wing mode.
Key Features
- Magnetic encoder positioning for controlled propeller stop position (Autocenter).
- Rated 170KV (Industry Professional Edition / energy efficient graphic).
- Maximum thrust shown: 30.4 kg (also shown as 30.4 kgf on product graphic).
- Recommended hover thrust shown: 10~13 kgf.
- Efficiency shown: >74% (graphic) and up to 84.2% (test table).
- ESC supports RS485 communication and digital throttle (by RS485).

Test notes shown: the graph/table data were measured with input voltage of 48 V at 25°C and sea level, and rotational speed was adjusted by the throttle. The above table data are theoretical values when the input voltage is 48.4 V for reference only. With room temperature of 25°C and no additional cooling device: current over 95 A is non-working zone; 40-95 A is short-term (about 10-30 s) working zone; below 40 A is sustainable working zone. Control motor running time according to ambient temperature and heat dissipation conditions.
