# TO THE QUESTION ABOUT THE AREA OF THE STATOR AND ROTOR SLOTS OF ASYNCHRONOUS COMMON INDUSTRIAL MOTORS

The influence of the number of poles, the number of teeth and the values of the magnetic induction of an induction motor on the area of oval and rectangular grooves is analyzed. The change in the values of the set of magnetic inductions does not affect on the area of the slots, with the number of grooves increasing, the total area of the slots increases, the character of the dependence is nonlinear. With an increase in the number of poles, the area of the oval grooves of the stator and rotor decreases, the area of the rectangular stator slots decreases with the transition from bipolar machines to four-pole machines, and then increases, the area of the straight-angle rotor slots decreases to eight-pole machines, increases with further increase.
