Exterior rotor brushless motor controller and what is the difference between the internal rotor brushless motor controller?
the motor controller of brushless dc motor controller generally can be divided into inner rotor and outer rotor, specific look at the two motor controller below:
standard generalized exterior rotor brushless motor controller B3725S
standard generalized inner rotor brushless motor controller B2430M
external rotor motor controller is the rotor pole outside. This kind of motor controller fixed part is coil, rotating part is the magnetic pole. inner rotor motor controller is rotor coil inside. The motor controller fixed part is the magnetic poles, rotational part is rotor coil. in general use are inside the rotor, is rotating coil. outer rotor, which is rotating magnetic pole motor controller is usually a particularly powerful.
