Electric machine, especially polyphase generator, has magnetically neutral distance holder arranged between pole fingers of two claw poles to fix fingers relative to each other in peripheral direction

摘要

The machine has a stator (12) fixed in a housing (11), a claw pole conducting part moving element (15) on a shaft (20) mounted in the housing and with two rotary claw poles (16,17) with axially mutually engaging pole fingers (18) that interact with the stator via an air gap (22) and that enclose a pole core (23) fixed to the housing with a stimulation winding (24). A magnetically neutral distance holder (25) is arranged between the pole fingers of the two claw poles so that it fixes the fingers relative to each other in the peripheral direction.
