Abstract: The present disclosure is directed to an energy storage and retrieval system for the generation of power. A compressor (301) pressurizes ambient air. The pressurized air flow passes through a thermal energy regenerator (280) for thermal energy storage and retrieval and onto an expander (302) for generating mechanical power. The compressor (301) and the expander (302) are coupled to an electrical machine (304) through a common shaft (303). The regenerator (280) comprises one or more Thermal Energy Storage (TES) units which can be coupled to one another in a parallel configuration. The TES units comprise a thermal medium for the storage and retrieval of thermal energy.

Abstract: An electric actuator includes an electric motor, a drive device that drives the electric motor to output a first rotary motion using power accumulated in a capacitor, and a motion converter that is coupled to the electric motor and converts the first rotary motion into a second rotary motion. The first rotary motion is forward and reverse rotary motions that are output by the electric motor as the drive device drives the electric motor to repeat forward rotation and reverse rotation. The second rotary motion is a unidirectional rotary motion. Regenerative electric power generated in the electric motor by the electric motor repeating the forward rotation and the reverse rotation is supplied to the capacitor.

Abstract: An electric motor comprises a stator presenting a first surface. A rotor is rotatable relative to the stator. The rotor presents a rotor raceway disposed in spaced relationship with the first surface of the stator. The first surface of the stator defines a plurality of slots in spaced relationship with one another to define a plurality of spaced teeth between the slots. At least one electrical conductor is disposed in each of the slots and configured to selectively create a moving magnetic field for acting upon the rotor for providing rotational movement of the rotor. A portion of the at least one electrical conductor extends substantially into radial alignment with, or past the first surface of the stator to at least partially define a stator raceway of the stator for engaging the rotor raceway of the rotor during relative radial movement between the rotor and the stator.

Abstract: A magnet includes one or more polar regions each having an arc shape and arranged in a circumferential direction. A magnetic focus center of each polar region is different from a center of an inner diameter of the one or more polar regions. A value obtained by dividing (i) dm, a distance from a straight line connecting ends of a first magnetic center line of the one or more polar regions to a center of the first magnetic center line, by (ii) db, a distance from a straight line connecting ends of a second magnetic center line of the one or more polar regions to a center of the second magnetic center line, satisfies certain values based on a number of the polar regions. db is determined based on the one or more polar regions having a magnetic focus center that corresponds to the center of the inner diameter.
