Description

technical field [0001] The invention relates to the technical field of brushless motors, in particular to a high-precision brushless motor provided with a torque sensor. Background technique [0002] The brushless motor relies on changing the alternating frequency and waveform of the current wave input to the stator coil of the brushless motor, and forms a magnetic field that rotates around the geometric axis of the motor around the winding coil. This magnetic field drives the permanent magnet on the rotor to rotate, and the motor It starts to rotate, because the input is DC, and the current needs an electronic governor to convert it into a 3-phase AC. It also needs to receive a control signal from the remote control receiver to control the speed of the motor to meet the needs of the model. [0003] Torque sensors, (also known as torque sensors, torque sensors, torque sensors, torque meters) are divided into two categories: dynamic and static, of which dynamic torque sensors...
