Abstract: A rotor assembly includes a rotor member and a plurality of permanent magnets. The rotor member has a hub with a central axis and a plurality of spokes extending radially outward relative to the hub. Each spoke has a radially inward end and a radially outward end. Each spoke also has a body section, a mounting section, and a flux barrier section. The body section extends from the radially outward end towards the radially inward end. The mounting section is interconnected to the hub. The flux barrier section is disposed between the body section and the mounting section and has at least one flux restriction web extending between the body section and the mounting section. The flux restriction web magnetically isolates the body section from the mounting section. A permanent magnet is disposed within each magnet-receiving slot between pairs of adjacent spokes. A motor with the rotor assembly is also disclosed.

Abstract: A combined electric motor and motor drive are provided. The electric motor and motor drive are attached together to form a co-packaged unit. In the co-packaged electric motor and motor drive, both the motor drive and the electric motor generate heat. A thermoelectric cooler is provided that may transfer heat away from the motor drive. The thermoelectric cooler may also insulate the motor drive from the heat generated by the motor.

Abstract: A method of balancing a rotor and/or fixing rotor components includes arranging a plurality of generally like laminations side by side in a stack to form at least a part of a rotor. The rotor has a rotational center axis and each of the laminations having a plurality of apertures that cooperate to form passages that extend axially along a length of the stack. In accordance with an aspect of the method, a polymer based fixation material is filled in the passages in a manner to fix the laminations together in the stack. With the fixation material, a sprue is formed, projecting from an axial face of the stack. In accordance with another aspect of the method, a weight of the sprue is adjusted to rotationally balance the rotor about the rotor center axis.

Abstract: A surge arrester system includes a surge arrester, and an active cooling system having a cooling interface in contact with the surge arrester and operative to transfer heat from the surge arrester. The active cooling system includes a forced convection apparatus operative to provide forced convection cooling. A circuit breaker system includes a power semiconductor switch and an active cooling system constructed to cool the power semiconductor switch. The active cooling system includes a forced convection apparatus configured to provide forced convection cooling. The power semiconductor switch is in contact with the active cooling system. A surge arrester is disposed adjacent to and in contact with the active cooling system. The active cooling system includes a cooling interface constructed for contact with the surge arrester and operative to provide cooling to the surge arrester. The power semiconductor switch and the surge arrester dissipate power alternatively.

Abstract: An electrical machine includes a stator and a rotor in magnetic communication with the stator. The rotor has a cage construction, the rotor having a plurality of passages extending therethrough from a first end of the rotor to a second end of the rotor. A rotor cage has two end rings, one of the end rings disposed at each of the first end and the second end of the rotor, and having a plurality of conductor bars extending through the rotor from the first end to the second end and coupled with the end rings. The conductor bars each include a transition region adjacent to each end ring, and a central region disposed between the two transition regions. Each transition region includes at least one conductor bar dimension that increases proximate the end rings.
