摘要： An N-phase electric machine, N being an integer ≥3, includes a housing; i×N stator windings arranged in a fixed manner in the housing, i being an integer ≥2; and a rotatable rotor surrounded by the i×N stator windings in the housing. The stator windings are consecutively divided into i subgroups in a circumferential direction, each subgroup having N stator windings. The electric machine further comprises i current control modules and i temperature measurement devices, each current control module being correspondingly electrically connected to the N stator windings in one corresponding subgroup, so that when the stator windings in the i subgroups are supplied with power by the i current control modules, a rotating magnetic field is generated around the rotor. Each temperature measurement device is configured to measure the temperature of one corresponding subgroup in the i subgroups during operation of the electric machine.
