The electric motor of this invention is a reluctance motor with a rotor (1) like a cogwheel made up of ferromagnetic materials having recesses (1b) and salient junctions (1a). Further, a position detector (6, fig. 6) is fixed at the rotor (1) due to control the rotor position. The stator consists of permanent magnets (2) and an additional coil (3) on the ferromagnetic yoke (4). The number of the poles of the stator is identical with the number of the salient junctions (1a) of the rotor (1). Each pole of the stator includes one pair of permament magnets (2) with a length of one pole pitch (T, fig. 5). The motor is driven by a power source (7, fig. 6) with an electronic part (8, fig. 6) which feed the coil (3) like as a motor during the first and third quarter of each pole pitch (T/4, fig. 5) and get current from the coil (3) like as a generator during the second and fourth quarter of each pole pitch. |
