Abstract

An electric machine comprises a rotor (10) and a stator (6) which includes a stator pack (7) made of ferromagnetic material having a plurality of slots (8), and stator windings (9), for defining a magnetic flux (Φ) having a maximum magnetic flux value (Φ1) defined on the basis of a first torque value (T1), associated with a nominal frequency (fn); the electric machine (2) being configured to supply a maximum torque (Tmax) equal to a first torque value (T1) when fed with a nominal voltage (Un) at a frequency lower than or equal to a nominal frequency (fn); the electric machine (2) being configured to supply, in continuous operation, a maximum torque (Tmax) equal to a second torque value (T2) when fed with a maximum voltage (Umax), higher than the nominal voltage (Un), at the maximum frequency ( fmax ).
