Abstract: An electric machine system described herein comprises a first and second electric machines configured to drive a load. The first electric machine has a plurality of first rotors driven using electric power having a first phase. The second electric machine has a plurality of second rotors driven using electric power having a second phase. The second phase differs from the first phase. Each of one or more shafts connects a first rotor with a second rotor. The first rotor is coaxial with and axially spaced apart from the second rotor.

Abstract: The invention relates to an electric motor having at least two stators disposed coaxially to each other and a rotor, wherein each stator has 2*n poles, with n=1, 2, 3, . . . , wherein each stator has at least one common coil or winding for all poles, wherein each stator has a first and second partial shell, wherein each partial shell has a shell bottom and n poles, wherein each pole is formed as a tooth extending in axial direction or substantially in axial direction and beginning on the shell bottom, wherein with assembled partial shells of a stator the tooth or the teeth of the first partial shell is or are disposed in alternating manner in circumferential direction with the tooth or the teeth of the second partial shell, and wherein with assembled partial shells or a stator, the at least one coil) or winding is received between the partial shells.

Abstract: An electric motor and conversion system includes a direct current power source, a rotor with two sides and two series of permanent magnets alternating in polarity, two stators on opposing sides of the rotor where each stator has a series of winding coils, magnet position identifiers, and a control system comprising a sensor that cooperates with the magnet position identifiers and a microcontroller to individually controls winding drivers. Preferably, the number of magnets on the rotor does not equal the number of winding coils on the stators. Also preferably, the magnet position identifiers are a series of apertures on the rotor through which signals pass. The conversion system can also include connectors for connecting to an axle, a removable throttle, and electric cables for electrically connecting the components.
