Abstract: A rotor assembly comprises a rotor core comprising a first end and an opposing second end, and an outwardly facing peripheral surface having a set of rotor teeth projecting outwardly therefrom to define a set of rotor slots therebetween. Each rotor tooth can comprise a first rotor tooth wall, an opposing second rotor tooth wall, and a distal tip between the first rotor tooth wall and second rotor tooth wall. Each respective rotor slot can be defined by a respective first rotor tooth wall of a first rotor tooth, and a respective second rotor tooth wall of a second rotor tooth, and includes a first rotor core conduit extending axially along a length of the first rotor tooth. The first rotor core conduit can comprise a first rotor core conduit inlet at the rotor core first end and a first rotor core conduit inlet at the rotor core second end, the rotor core conduit defining a first taper that is narrower at first rotor core conduit inlet than the first rotor core conduit outlet.

Abstract: A rotating electric machine system is equipped with a rotating electric machine including a rotating shaft and a permanent magnet, and a housing in which the rotating electric machine is accommodated. A bearing is interposed between the housing and the rotating shaft. The bearing is retained by a hollow tubular shaped bearing holder. The bearing holder includes a cover member that covers the bearing from an outer side in a diametrical direction of the rotating shaft. An insulating element is interposed between an outer circumferential surface of the bearing and an inner circumferential surface of the cover member.

Abstract: An electric assembly includes a box assembly, a motor, and a transmission. A mounting plate is disposed in the box assembly, and the mounting plate divides a space within the box assembly into a motor holding cavity and a transmission holding cavity. The motor is disposed in the motor holding cavity. The transmission is disposed in the transmission holding cavity, and the motor is power-coupled to the transmission such that the motor and the transmission are directly integrated through the box assembly without external connection of the motor and the transmission. The mounting plate is a monolithically integral part of the box assembly.

Abstract: The present disclosure provides a superconducting power generation device and a power generation method. The device includes a superconductor, a conductive coil, a permanent magnet and a cooling medium. When ambient temperature is lower than its superconducting critical temperature, the superconductor, made of the second-type superconducting material, is capable of generating a magnetic levitation force to an outer permanent magnet and levitate it. When an external force is applied to the permanent magnet, its position changes compared to the conductive coil, which affects the magnetic flux passing through the coil and induces the generation of electromotive force in the coil, thereby converting mechanical energy to electric energy. By using the device provided by the present disclosure, the conversion from the mechanical energy to the electric energy in an ultra-low temperature environment can be achieved, and thus, problems about energy sources on low-temperature celestial bodies in extrasolar systems are solved.

Abstract: A stator cooling channel includes an end channel formed in a housing protrusion and connecting to a coil end accommodation channel. A terminal base is positioned on one side in a direction of an axis with respect to the end channel of the housing protrusion and includes a part facing the stator cooling channel. This structure serves to reduce the size of the electric motor in the radial direction.

Abstract: A stator cooling housing for a stator of a rotary electric motor includes a cylindrical frame adapted to be mounted around an iron core and having an outer lateral surface and inlet and outlet channels. A cylindrical jacket is arranged against the outer lateral surface of the cylindrical frame. The cylindrical jacket comprises an inner side having a plurality of cylindrical grooves forming with the outer lateral surface of the cylindrical frame adjacent fluid cooling channels arranged around the cylindrical frame from a frame upper portion to a frame lower portion. Fluid communication portions are arranged such that a cooling fluid is enabled to run from the inlet channel, through the adjacent fluid cooling channels from the frame upper portion to the frame lower portion, and through the outlet channel to form a cooling circuit.
