A ring shaped permanent rotation magnet system (5) is arranged on at least one side (3) of the rotor system (2). The system is divided in at least two sectors (7,8), one of which has a first magnet pole orientation and the other an opposed orientation or ferromagnetic characteristics. At least one permanent lifting magnet (17,17') is arranged before the magnet poles of the rotation magnet system. With cyclic attraction and repelling by the system (5), the lifting magnet is located reciprocating linearly at a motor frame (21) and coupled with a crankshaft (23). A bevel gearing (24) couples the crank shaft with the rotor shaft (1). An electrically driven bridging magnet (12) produces an alternating magnetic field, to provide the compensation for instantaneous repelling force in the sectors (7,8).
