Number Of Slots Per Pole Per Phase

The distribution factor Kd for a given number of phases is dependent only on the number of distributed slots under a given pole. It is independent of the type of the winding, lap or wave or the number of turns per coil, etc. The distribution factor decreases as the number of slots per pole increases. The stator has 3 slots per pole per phase and 10 conductors per slot. Calculate (i) the number of poles, and (ii) useful flux per pole. Assume all the conductors per phase to be connected in series and the coils to be full- pitch. Example (11) DREAM A Hz, star connected a ernator as s Ots With 4 conductors per slot. Coils are short-pitched by 3. Effect of the number of slots per pole on performance of permanent magnet generator direct-driven by wind turbine. August 2011; DOI: 10.1109/ICEMS.20. The Number Of Slots Per Pole Per Phase Keep in mind that such special offers are limited in time. For example, a promotion can only be valid for 2-3 hours, with The Number Of Slots Per Pole Per Phase free spins available for 30-40 minutes. The number of poles reflects the synchronous speed of the motor. The 2-pole synchronous speed is 3000r/min, the 4-pole synchronous speed is 1500r/min, the 6-pole synchronous speed is 1000r/min, and the 8-pole synchronous speed is 750r/min. Number of poles of the motor: The number of poles of the motor determines the synchronous speed of the motor.

Abstract: This paper presents a feasibility study between a design for synchronous reluctance (SyncRel) motors with integer slots/pole, i.e. 36 slots/4poles and fractional slots/pole, slots per pole ratio higher than 3, i.e. 18 slots/4poles configuration. The analysis is extended also to low energy permanent magnet assisted synchronous reluctance motor (PM SyncRel). It is found that the integer slots/pole solution have a better efficiency for SyncRel, while fractional slots/pole solutions benefit the PM SyncRel design. Potentially, integer slots/pole designs might have higher torque ripple and lower power factor than fractional slots/pole solutions. The presence of very low energy permanent magnets, as bonded plastic ferrite leads to significant increase in the constant torque speed range and power output.
