Title:
EXTERNAL STATOR OF AN E-MOTOR WITH STATOR TOOTH GROUPS, EACH OF WHICH HAVING TWO ADJACENT STATOR TEETH AND A CONNECTION YOKE
Document Type and Number:
WIPO Patent Application WO/2019/154658
Kind Code:
A3
Abstract:
The invention relates to an external stator of an induction machine having an internal rotor (9, 10), which has a number N of stator teeth (1) which form a number N/2 of tooth groups (ZGi; i=1..N/2). Each stator tooth (1) has a pole core (1b) and a pole shoe (1a) formed thereon, wherein the pole cores (1b) and the pole shoes (1a) are produced from a first material (MA1). Each tooth group (ZGi) is formed by two directly adjacently arranged stator teeth (1) and a magnetic yoke (15). At least one intermediate element (11, 21, 31) is arranged between two adjacent stator teeth (1) of adjacent, different tooth groups, said intermediate element extending in the axial direction of the stator (1). Each intermediate element (11) is produced from a second material (MA2) which differs from the first material (MA1) of all the tooth groups (ZGi). Two stator teeth (1) with a magnetic yoke (15) and the opposing rotor poles (9, 10) each form a magnetic circuit (MF).
