Product overview
The Kpower 4012 External Rotor Brushless Motor is a motion component for applications including industrial drones, floor-cleaning robots, agricultural seeders and toilet robots. Its external-rotor architecture incorporates an application-oriented wound magnetic circuit, a built-in magnetic encoder and an FOC controller. Multiple closed-loop configurations support position and current control. For mechanical integration, the motor measures Φ47.8x20.2mm and weighs 132g; its electrical interface uses UART TTL communication, and its magnetic encoder is specified at 14bit.
The motor operates across 9-16V, with a rated voltage of 12V. Its rated specifications are 0.13N·m torque, 0.95A current, 400RPM speed and 7.4W power. Peak torque is 0.2N·m and peak current is 2A, while no-load operation is specified at 950RPM and 115mA. Maximum efficiency is 65%, and the motor has 10 pole pairs. Integration must accommodate the -10~50°C working temperature range and IP42 water-resistant protection. Service life is stated as up to 2000 hours.
