# rotor bars and # stator slots in induction motor
Are there any generalizations that can be made about the # rotor bars and # stator slots in an induction motor?
One thing I know is that most higher-speed windings are integral-slot (vs fractional-slot) windings, the number of stator slots is divisible by 3 and by the number of poles.
Are there any other generalizations that can be made?
The reason is that vibration spectra sometimes show rotor bar pass frequency and stator slot pass frequency... but may not be able to distinguish if we haven't inspected the motor to count the number of bars and slots.
