Summary: | An electric machine (Fig. 3, 10) comprises a housing (Fig. 3, 11), a rotor 13 comprising a shaft 15 and a rotor laminated core 16, and a stator 12 comprising a stator laminated core 17. The stator laminated core comprises grooves (slots) 18 in which stator windings 19 are received. A respective tooth 21 of the stator laminated core is arranged between two respective grooves that are arranged adjacent to one another in the circumferential direction. An annular gap 24 is formed between the rotor laminated core and the stator laminated core. A tooth head ring 25 is arranged in the annular gap. The tooth head ring has recesses 27 arranged between two tooth heads 26 that are arranged adjacent to one another in the circumferential direction of the tooth head ring. The relative position of the stator laminated core and the tooth head ring is adjustable. In a first relative position of the stator laminated core and the tooth head ring, the tooth heads of the tooth head ring radially inwardly abut the teeth of the stator laminated core. In a second relative position, the tooth heads radially inwardly abut the grooves of the stator laminated core. The relative position may be adjusted by an actuator (Fig. 3, 29). Either the stator or the tooth head ring may move, with the other fixed in place to the housing. |
