摘要： A homopolar electrical machine (10) includes a stator having a stationary magnetic core (28) and multiple stator windings (32) disposed within the stationary magnetic core (28). A rotor (12) includes a first set of pole pieces (22) at a first end of a shaft (14) and a second set of pole pieces (24) at a second end of the shaft (14). The pole pieces (22, 24) are separated by air gaps (38). The rotor (12) is a one-piece structure having only the shaft (14), the first set of pole pieces (22), and the second set of pole pieces (24) integrally formed from a single material. A stationary field coil (40) is coupled to the stator. The stationary field coil (40) includes a cryostat (41) configured to cool the stationary field coil (40) to superconducting temperatures. The stationary field coil (40) has a coil diameter that is at least partially greater than an outer diameter of the rotor (12). Each stator winding (32) is unitarily formed as a single structure that extends along a length of the homopolar electrical machine (10) beyond the first and second sets of pole pieces (22, 24) and is disposed within an air gap (33) of the homopolar electrical machine (10).

摘要： The present invention relates to an electrical machine having a rotor (4), a stator (7, 8), a rotating-field production device and a pole-field production device (9), in which the rotor (4) can rotate about a rotation axis which passes through two further opposite sections (5, 6) of the rotor (4), and with the rotating-field production device being designed to produce an essentially radial magnetic field which rotates about the rotation axis of the rotor (4), and with the pole-field production device (9) being designed to produce a magnetic field of opposite polarity to the rotor (4) on the opposite sections (5, 6). In order to reduce the size of the electrical machine without reducing the power, the pole-field production device has at least one magnet (9).

摘要： A low inductance electrical alternator or motor (1) with low armature inductance is disclosed. Arrangements of complementary armature windings (40) are presented in which the fluxes induced by currents in the armature windings (40) effectively cancel leading to low magnetic energy storage within the machine (1). This leads to low net flux levels, low core losses, low inductance and reduced tendency toward magnetic saturation. Separately excited field arrangements are disclosed that allow rotor motion to effect brushless alternator or brushless motor operation. An exemplary geometry includes a stator (2) including two toroidal rings (4, 6) and a concentric field coil (8) together with a rotor structure (22, 24, 25) separated from the stator (2) by four air gaps (54, 56). An alternate embodiment allows for counter-rotation of two rotor elements (24) for use as a flywheel energy storage system in which the external gyroscopic effects cancel.

摘要： The present invention relates to a universal electric motor with variable air gap. It has a rotor (1) with one or more attraction steps and a stator (2) provided with an excitation system. The excitation system comprises, mounted consecutively distanced on a stator support (20) facing the rotor (1), at least an electromagnet (21), provided with an armature (24) and with a winding (25), a control circuit (22), provided with a position detector (26) for supply power to the electromagnet, and a permanent magnet (23). The electromagnet (21) and the permanent magnet (23) are fastened onto the stator support (20) to excite the rotor alternatively, and in adjustable positions to change the direction of rotation of the rotor itself.

摘要： A motor/alternator is formed by a single toroidal magnet (2), which may be a hybrid magnet including a permanent magnet (12) and an electromagnet (14) concentrically arranged, having flux conductors (4, 6) which, in combination with flux switches (44), create an alternating magnetic circuit around a power coil (8). The motor/alternator minimizes the amount of material experiencing hysteresis by making the flux switches (44) small and reduces eddy currents in the flux conductors (4, 6) by using a material very resistant to eddy currents. The subsequent reduction in core losses allows for very high electronic frequency operation and thus a high power density. The form of the flux conductors (4, 6) allows for a high number of poles in the motor/alternator thus enabling a high electronic frequency at modest rotational speed.

摘要： A low inductance electrical machine (1) that may be used as an alternator or motor with low armature inductance is disclosed. Arrangements of complementary armature windings (40A, 42A) are presented in which the fluxes induced by currents in the armature windings (40) effectively cancel leading to low magnetic energy storage within the machine (1). This leads to low net flux levels, low core losses, low inductance and reduced tendency toward magnetic saturation. The inclusion of additional gaps (54, 56) in the magnetic circuit allows for independent adjustment of air gap geometry and armature inductance. Separately excited field arrangements (8) are disclosed that allow rotor (22, 24, 25) motion to effect brush-less alternator or brush-less motor operation. An exemplary geometry includes a stator (2) including two annular rings (4, 6) and a concentric field coil (8) together with a rotor structure (22, 24, 25) separated from the stator (2) by four air gaps (50, 52, 54, 56).
