Abstract:
An electrical machine, in particular a starter-generator, having a permanent-magnetically excitable rotor (19) and a stator (16) the stator (16) carrying a multiphase winding (38), having an inverter (22) which is variable by means of a regulating or control device (23) and by which the stator (16) can be operated in the field attenuation mode, characterized in that the stator (16) has a number of poles equivalent to n times the number of phases of the multiphase winding (38) in the stator (16), and each phase winding (36) comprises at least one coil (34), and all the coils (34) of the multiphase winding (38) are disposed side by side in the stator (16), and the rotor (19) has a number of poles equivalent to n times the number 4, one pole (32) of the stator (16) having a maximum width of a pole pitch (Tp), and the spacing (A) of two poles (32) of the stator (16) being equivalent to at least one-third the pole pitch (Tp).
