The present invention is an energy storage apparatus having a rotor and a stator. The stator includes a bobbin having a cylindrical shape and open at each end. The bobbin includes at least one fin extending longitudinally on an exterior surface of the bobbin. The bobbin also includes a phase winding longitudinally and circumferentially encircling said bobbin. The winding is separated by at least one fin. The bobbin also includes at least one cooling passage for transporting a cooling medium.

Stator cooling

The present invention is a methodology for assembling a magnet onto a rotor for an energy storage apparatus. The methodology includes the step of mounting a magnet onto a mandrel. The methodology also includes the step of turning an outer diameter of the magnet to a predetermined size. The methodology further includes the step of turning a rim section of the rotor for receiving the magnet to a predetermined size. The methodology still further includes the step of attaching the magnet to the rim section. The methodology includes the step of removing the mandrel.

Assembly process of magnet onto a rotor

The present invention is a methodology for assembling a winding around a stator for an energy storage apparatus. The energy storage apparatus includes a rotor and a stator. The methodology includes the step of positioning a preformed winding around the stator. The methodology also includes the step of dividing a forming fixture into a plurality of segments. The methodology further includes the step of positioning the forming fixture around the stator shaping the winding. The methodology also includes the step of potting the winding.

Method for assembling a stator

A method for fabricating a stator of an induction motor having a cooling jacket extending around the stator, the method including the steps of welding a channel upper surface and a channel lower surface to an inner channel side surface to create a cooling jacket, coating the inner diameter of the cooling jacket with an oxide layer, heating the cooling jacket to expand the cooling jacket, sliding the cooling jacket over the stator, and cooling the cooling jacket to contact the cooling jacket into positive engagement with the stator such that the cooling jacket is fixedly secured thereto.

Stator fabrication process

The present invention is an energy storage apparatus. The energy storage apparatus includes a rotor. The rotor includes a rim. The rim includes a plurality of disks. The disks are bonded together to maximize rim balance and minimize a bonding stress between adjacent disks.

Segmented rim construction for a rotor

An induction motor includes a stator defining stator inner and outer diameters extending about a longitudinal axis, the stator includes a plurality of windings extending longitudinally and circumferentially about the longitudinal axis between the stator inner diameter and the stator outer diameter and passing an electric current therethrough to create a magnetic field, a rotor extends along the longitudinal axis having a rotor length and a rotor outer diameter less than the stator inner diameter, the rotor being rotatable about the longitudinal axis relative to the stator, the rotor including at least one electrically conductive bar extending parallel to the longitudinal axis adjacent the rotor outer diameter for receiving an induced current due to the magnetic field, an end cap at each end of the rotor contacting the at least one electrically conductive bar and a capture ring attached to each end of the rotor to prevent movement between the end caps and the rotor.

End cap to rotor attachment

An induction motor includes a stator defining stator inner and outer diameters extending about a longitudinal axis, the stator includes a plurality of windings extending longitudinally and circumferentially between the stator inner diameter and the stator outer diameter and passing an electric current therethrough to create a magnetic field, a rotor extending along the longitudinal axis having a rotor outer diameter less than the stator inner diameter, the rotor rotates about the longitudinal axis relative to the stator in response to the magnetic field, and a stator thermal exchanging fluid circuit extending both through and about the stator whereby the stator thermal exchanging circuit exchanges thermal energy with the stator.
