<p>The stator 50 of an electric machine 30, e.g, a universal motor, has stator poles 36,38 receiving field windings 32, 34, at least one pole (winding holder) 36 having a larger winding width X3 than width X1 of the other pole 38. Pole 36 has its circumference flattened so as to define an increased gap 66 between the stator and the housing 18, which gap may accommodate the switch actuator 20 and/or electrical/electronic components, fluid/signal lines, and electrical conductors. The stator may comprise two parts 76,78 divided along line 68 at 70. The present stator allows for the hand grip section of a power tool e.g. a grinder, to be of reduced cross section.</p> |
