This simplifies motor construction, reducing its cost as well as eliminating the additional wiring and connections to the motor that would otherwise be needed to support the sensors. Sensorless Bldc Motor Controller Ic By monitoring the back EMF, a microcontroller can determine the relative positions of stator and rotor without the need for Hall-effect sensors. Driving a BLDC motor While an 8-bit microcontroller allied to a three-phase inverter is a good start, it is not enough for a complete BLDC motor control system. A pair of Hall-effect sensors is linked to each coil. (Courtesy of Atmel.) A pair of Hall-effect sensors determines when the microcontroller energizes a coil.
