Concentrated winding in bldc
WebIn the 4-pole, 6-slot, SPM, concentrated winding type BLDC motor, as opposed to a 24-slot distributed winding BLDC motor, a pole interval is 90° and a stator slot interval is 60°. A back electromotive force voltage induced from a phase winding of the stator 31 is caused by changes of the magnetic flux linkage. WebBLDC motor, the stator windings should be energized in a sequence. It is important to know the rotor position in order to understand which winding will be energized following the energizing sequence. Rotor position is sensed using Hall effect sensors embedded into the stator. Most BLDC motors have three Hall sensors embedded
