Product overview
The Kpower 6525 External Rotor Brushless Motor is a motor component for applications including industrial drones, floor-cleaning robots, agricultural seeders and toilet robots. Its external-rotor architecture combines an application-oriented wound magnetic circuit with a built-in magnetic encoder and FOC controller. The motor measures Φ65.5x23.6mm and weighs 210g, defining its physical integration envelope. Control provisions include multiple closed-loop configurations for position and current, UART TTL communication and a 14-bit magnetic encoder. The motor has 14 pole pairs.
Electrical integration requires a 9-28V supply range, with a rated voltage of 14.4V. Rated output figures are 0.33N·m torque, 400RPM speed and 17.3W power, with rated current of 1.6A. Peak torque is 0.85N·m and peak current is 4.8A; no-load figures are 700RPM and 200mA. Maximum efficiency is 75%, while KV is listed as N/A. Operating limits include a working temperature range of -10~50°C and IP42 water resistance. Service life is stated as up to 2000 hours.
