APPARATUS, SYSTEMS, AND METHODS FOR INCREASING AIRFLOW THROUGH INDUCTION MOTORS
First Claim
1. A rotor core assembly of an induction motor, comprising:
- a plurality of rotor laminations, each rotor lamination comprising;
a plurality of slots arranged around an outer radial periphery of a rotor lamination and passing through the rotor lamination, each slot configured to receive a rotor conductor bar there through;
a first row of vents passing axially through the rotor lamination; and
a second row of vents passing axially through the rotor lamination.

Abstract
Induction motors may have a rotor core assembly that includes a plurality of rotor laminations having an arrangement of vents therein. The arrangement of vents may provide increased airflow through the induction motor without adversely affecting the electromagnetic properties of the motor. The arrangement of vents includes first and second circular rows of vents, wherein each vent of the first row may be radially aligned with a respective vent of the second row, and each radially aligned pair of first and second row vents may be radially aligned with a respective conductor bar slot in the rotor lamination. The number of rotor bar slots may equal the number of first row vents and the number of second row vents. Systems and methods of facilitating ventilation in an induction motor are provided, as are other aspects.
