SLOT CONFIGURATION OF AN ELECTRIC MACHINE
First Claim
1. A stator of an electrical machine, the stator comprising:
- an elongate core defining an inner volume to receive a rotor of an electric machine; and
the core comprising a yoke and an array of teeth extending from the yoke toward the inner volume, the array of teeth defining slots between each pair of adjacent teeth in the array, each slot comprising;
a first slot region adapted to hold at least a portion of a conductive winding and defined by two non-parallel opposing slot side portions, anda second slot region adapted to hold at least a portion of a conductive winding and defined by two parallel opposing slot side portions.

Abstract
A stator includes an elongate core defining an inner volume to receive a rotor of an electric machine. The core includes a yoke and an array of teeth extending from the yoke toward the inner volume. The array of teeth defines slots between each pair of adjacent teeth in the array. Each slot includes a first slot region adapted to hold at least a portion of a conductive winding and a second slot region adapted to hold at least a portion of a conductive winding. The first slot region is defined by two non-parallel opposing slot side portions, and the second slot region is defined by two parallel opposing slot side portions.

16. An electrical machine comprising:
-
a stator comprising an elongate core to internally receive a rotor of an electric machine; and the core comprising a yoke and an array of teeth extending from the yoke, the core defining slots between neighboring teeth in the array, each slot having a depth defined by the yoke and one pair of neighboring teeth, each slot having a non-uniform width along a first portion of the depth of the slot, each slot having a uniform width along a second portion of the depth of the slot. - View Dependent Claims (17, 18, 19, 20)
