An electrical machine includes a stator having circumferentially arranged winding heads, with a winding head space being defined radially beneath the winding heads. Interacting with the stator is a rotor which has a rotatable laminated core. A magnetic brake is received in the winding head space and includes a magnet module having at least one permanent magnet which is axially resiliently fixed and constraint against rotation and which is magnetized in an axial direction, and an electromagnet which is arranged axially adjacent to the permanent magnet and securely fixed thereto. The electromagnet produces a magnetic field with a main direction oriented in an axial direction. Interacting with the at least one permanent magnet and the electromagnet is a ring-shaped armature which is secured directly and rigidly to the rotor so as to establish a fixed rotative engagement between the armature and the rotor.
