—— 英文：back emf at 1000 rpm( 1000转/分时的反电动势 )
As the back EMF is generated from the rotor is moving through the magnetic field generated by the permanent magnets, the back EMF is directly proportional to the motor speed, and the motor voltage constant. The motor voltage constant includes parameters like magnetic field strength which are also...
