摘要： An electric motor apparatus is described that utilizes a Halbach array and a ferrofluid core. The electric motor comprises a rotor assembly and a stator assembly, each of which utilizes a Halbach array. A ferrofluid core is utilized in the stator, which results in a motor that is less susceptible to core loss and operates with increased efficiency.

摘要： In a DC-motor according to the present invention, contact areas of first brushes can be enlarged without enlarging the external diameter of a disk on which a commutator is provided; therefore, the wear resistance of the first brushes can be enhanced while maintaining a good control-response; and at the same time, the axial dimension can be shortened dramatically, so that the DC-motor can be downsized.The first brushes 14 are radially in contact with the commutator 11, and second brushes 15 are axially in contact with slip rings 12 that are formed circumferentially inside the commutator 11.

摘要： A commutation apparatus drives a brushless motor having a stator equipped with a plurality of coils and a rotor. The commutation apparatus comprises a rotatable commutator shaft, two or more conducting rings carried discretely about the shaft, and two or more conducting segments carried discretely about the shaft at staggered positions along or near a plane perpendicularly intersecting the shaft. Each conducting segment is electrically connected to one of the conducting rings. Two or more electrical source contacts are provided for rotatably connecting a power supply across pairs of the conducting rings. A plurality of electrical load contacts is further provided for sequentially, rotatably connecting the conducting segments to discrete coils of the brushless motor.

摘要： The Stationary Armature Machine (SAM) comprised of a stationary armature, a stationary commutator affixed to the frame or housing and a rotating field and brushes affixed to a common shaft as a means for mechanical commutation of electrical currents based on Lorentz' force law. SAM's unique stationary armature increases current carrying capacity and heat abatement at low voltages and high rotating speeds without increasing overall physical size relative to BLDC motors. SAM's armature and field structure are arranged in reverse having the armature in a stationary position with a commutation assembly affixed to the machine's housing while said field structure (and brush assembly) rotate at the center of the machine. By making the armature and commutator assembly stationary, the current carrying conductors can be made much larger without being subjected to extreme centrifugal forces at high rotating velocities. SAM is ideally suited for applications that require high torque and power at high rotational speeds in a small inexpensive package.
