This paper presents an advanced method of selecting the number of poles slots so as to reduce the vibration of a traction motor for a gearless elevator system. The vibration source, i.e., the radial electromagnetic force, of the prototype was examined through its analytical derivation. The expression indicated the vibration orders and frequencies of the radial electromagnetic force that was caused by the interactions within or between armature reaction and permanent magnet fields including the stator slotting effect. More specifically, the prototype with 14 poles and 18 slots displayed a problem in terms of the vibration at the two times line frequency; this was due to the lowest vibration order 2. The vibration at two times line frequency was decreased by approximately 77.27% through a selection of 24 poles and 54 slots with a lowest vibration order of 6. A tower test was then conducted in order to validate the proposed method. Finally, an experiment on models having other rated load and pole-slot combinations was also carried out to improve the overall reliability.
