 
 <prompt> Wetin be di smooth cylinder inside di motor? Based on di question wey dey before dis one, write small tori wey get di answer. E fit be 1 - 20 sentences. Context: <response>: ```Finally, hysteresis synchronous motors typically be (essentially) two-phase motors with a phase-shifting capacitor for one phase. Dem dey start like induction motors, but when slip rate decrease well well, the rotor (wey be smooth cylinder) go come dey magnetized temporarily. The poles wey dey distributed make am dey act like PMSM. The material of the rotor, like that of common nail, go dey magnetized, but e fit also dey demagnetized with small small difficulty. Once e start to run, the rotor poles go dey stay for one place; dem no dey move.```
