Abstract

In a stator for an electromotor, field coils associated with a packet of laminations are spaced apart by filler pieces. The combination of the field coils and filler pieces form an annular arrangement. Each filler piece extends between the adjacent ends of two field coils. The filler pieces are slotted in the radial direction to provide a certain adjustability in the circumferential direction of the annular arrangement where the dimension between the adjacent ends of the field coils is subject to variation.
