An Analytical Approach to Solving Motor Vibration Problems movement. On 4 pole motors the distance between the nodes is only 45 mechanical degrees, ½ that seen on 2 pole motors, thereby making the 4 pole stator core much stiffer to movement resulting in much lower twice line frequency vibration. Calculations on a typical 1000 HP two pole motor at 60 Hz show 120 Hz vibration at the stator core OD of about 6-pole, 9-slot Motor and 8-pole, 9-slot Motor Manufacturer of high-performance rare earth magnets, NdFeB, SmCo.

24 slots and 8 poles motor configuration which is selected initially for the prototype model. Firstly, the slot area was insufficient to accommodate the calculated number of turns for 25MGOe magnet flux even though the packing factor is less than 0.4. Secondly, the overhang thickness was more than the
A. Development of 6-phase, 18-slot, 8-pole Winding Many feasible slot - pole combinations exist for fractional-slot per pole per phase machines [26], [27]. The 9-slot, 8-pole winding configuration inherently suffers from presence of large space harmonics in the stator MMF and unbalanced magnetic forces [14]. Converting a 4 Pole Motor to 8 Pole - CR4 Discussion Thread Re: Converting a 4 Pole Motor to 8 Pole 08/03/2012 9:06 AM You need to check with a qualified rewinder to see if the number of slots existing on the stator will allow an 8 poles configuration. SPM Motor | Magnetic Circuit Analysis | Shin-Etsu Rare ... The least common multiple for 6 poles and 9 slots is 18; for 8 poles and 9 slots, 72. The number of poles and the number of slots for a normal concentrated winding motor is set in a ratio of 2:3, but by working on the winding wires, it is possible to make an 8-pole motor even with 9 slots.
