Title: ASYNCHRONOUS MACHINE
Abstract:
For an asynchronous machine (1), in particular for use in electric vehicles or hybrid vehicles, comprising a rotor (10) and a stator (20) which surrounds the rotor (10), wherein an external stator yoke (21) with a stator yoke height (h21) is formed on the stator (20) and a large number of radially inwardly projecting stator teeth (22) of the same length are formed on the stator yoke (21), wherein a stator slot (23) is respectively formed between adjacent stator teeth (22), wherein an internal rotor yoke (11) is formed on the rotor (10) and a large number of radially outwardly projecting rotor teeth (12) of the same length are formed by the rotor yoke (11), wherein a rotor slot (13) is respectively formed between adjacent rotor teeth (12), wherein the asynchronous machine is of six-phase design, it is proposed that a total number (N1) of stator slots, which denotes the total number of stator slots (23) formed on the stator (20), is seventy-two.
