摘要： A commutator motor capable of utilizing any of dc and ac power supplies and superior in the function of preventing the burning of coil wires during overload. This commutator motor includes an iron core having a plurality of slots, a rotary shaft inserted centrally through the iron core, and a pair of first and second commutators mounted on the rotary shaft at both ends of the iron core. The first commutator has a first coil wire connected thereto, the first coil wire being wound on the bottom of the slot to form an inner coil portion. The second commutator has connected thereto a second coil having a smaller diameter than that of the first coil wire, the second coil wire being wound on the inner coil in the slot to form an outer coil portion.

摘要： A technical problem with a four pole wave wound direct current motors is that excessive currents flow in single turn windings when such a motor is operated at relatively low speeds and/or relatively high voltages, and that plural turn windings can not be formed for a reduced number of commutator segments or from heavy gauge rectangular wire, to efficiently fill armature slots. This problem is solved by a plural turn winding (19) having two ends (95, 97) for connection to commutator segments substantially 180o apart on the armature (10) and with at least four sides (82, 84, 86, 88) defining at least two open turns, for engaging slots (17) in the armature core (16) which are spaced substantially 90o apart. A three open turn winding (100) is also disclosed. The number of open turns is limited only by space available in the armature coil slots (17).

摘要： The invention relates to electrotechnical and mechanical engineering, in particular to the structural embodiment features of electric motors, mainly for means of transport. Said invention is characterised in that the inventive electric motor consists of a rotor (3) provided with electromagnets (6), a stator (2) comprising a circular magnetic circuit (4) which is provided with an even number of permanent magnets (5) fixed thereto at an equal distance from each other, a distribution manifold (7) which is provided with conductive plates (9) and arranged on the stator body and current collectors (8) connected to the coil windings of the rotor electromagnets. According to said invention, the coil windings of the adjacent rotor electromagnets are connected to each other pairwisely in series aiding and connected in series opposition to the coil windings of the pair of diametrically opposite electromagnets. In addition, capacitors are connected to the ends of the winding, which are connected to the collectors, in such a way that resonance circuits are formed, the number (n) of the stator permanent magnets and the number (m) of said resonance circuits are defined according to a relation n=10+4k, wherein k=0, 1, 2, 3, , the number of the collector plates of the distribution collector is equal to the number of the stator permanent magnets, the central lines of the dielectric gaps (10) of the distribution collector are oriented along the central lines of said magnets. Said invention increases the torque of the electric motor.
