An electrical machine, in particular a brushless synchronous motor has a stator ( 14 ) and a rotor ( 12 ) with salient poles ( 18 ) disposed distributed over its circumference, each of which poles has an enclosed permanent magnet ( 11 ) and a pole shoe ( 19 ) that extends radially outward from the permanent magnet and defines an air gap ( 13 ) between the stator ( 14 ) and rotor ( 12 ). In order to achieve a low cogging torque and a low torque undulation, the pole shoes ( 19 ) are embodied as magnetically anisotropic, with a preferred direction of the greater magnetic conductivity extending parallel to the radial salient pole axis.
