Bar Inductor Machine

The invention is devoted to contactless electric machines and can be applied on alternative power engineering. Its goal is to increase the generated power at low rotation frequencies and to decrease the starting torque. The offered bar-type inductor machine contains magnetic circuit (1) of the stator, anchor winding (2), rotor shaft (7), and ferromagnetic bars (6) of the rotor and springs (8). The invention is characterised by the fact that the number of stator's teeth (3) in the magnetic circuit (1) and the number of rotor's ferromagnetic bars is (6) has been doubled. The rotor ferromagnetic bar springs (8) are fixed between holders (9) and shifted ferromagnetic cylinders (5), to which the permanent magnets (4) are fixed. If the rotor shaft (7) starts rotation, it causes changes of magnetic flux producing emf in anchor winding (2). The shifted ferromagnetic cylinders (5) change their position decreasing air gap.
