PURPOSE:To eliminate the failur such as wear or the like of the conventional commutator brush in a motor by eliminating the commutator by simplifying windings. CONSTITUTION:This motor consists of field windings L1, L2 and induction windings L1a, L2a in a manner that the windings L1, L2 are connected at respective one ends thereof to each other to a DC power supply and at the other ends thereof to the collectors of transistors Tr1, Tr2 and the windings L1a, L2a are connected to the transistors Tr1, Tr2 with a permanent magnet rotor provided between the respective field windings and the induction windings. When the rotor is revolved, magnetic field is altered to allow the induction current flowing through the windings L1a, L2a to be amplified by the transistors Tr1, Tr2 to thereby the collector currents to flow through the field windings. Thus, it can switch the current without using a commutator to thereby revolve the rotor. |
