摘要： An electric drive unit and method of assembling the same is disclosed. The electric drive unit includes a rotor having a rotor shaft, and gear shaft, where the rotor shaft is inserted into the gear shaft. The gear shaft is supported by two bearings, while the rotor shaft supported directly at one end by a bearing and at the other by the gear shaft. A wave spring is also disclosed that provides an axial loading to the rotor shaft. Also disclosed is a balancing ring secured to an end of the rotor via a locknut. The balancing ring can be machined in order to balance the rotor. The rotor shaft can be connected to the gear shaft via a spline connection. The rotor shaft can bear against the gear shaft via a pilot journal and pilot bore defined on the rotor shaft and gear shaft respectively.

摘要： The present invention relates to a slotless motor including a thin-walled hollow rotor body 100, and methods of manufacture of such rotors, the methods including hot forming and machining steps. The rotor body has a rotational axis 102 and comprises a first cylindrical portion 104 having a first diameter, a second cylindrical portion 106 having a second diameter, larger than the first diameter and a third cylindrical portion 108 having a third diameter, smaller than the second diameter, the third cylindrical portion located at a second end of the rotor body 100. A first end cap 110 joins the first and second cylindrical portions together, and a second end cap 112 joins the first and second cylindrical portions together. The first, second and third cylindrical portions are all arranged coaxially with the rotational axis 102 of the rotor 100 such that the second cylindrical portion 108 and the first and second end caps collectively define a hollow cavity 114 in the rotor body 100. The rotor body 100 may be provided with a Halbach array.

摘要： A rotor includes an assembly of laminations including a plurality of radially-projecting poles, a winding of electrically conductive wires to be wound around each pole by means of wire-guiding heads arranged axially on either side of the lamination assembly. A guiding head support is inserted between the lamination assembly and each guiding head such that: an internal radial face of the support abuts against an external radial face at an axial end of the lamination assembly; and a peripheral surface of the support, which projects axially outward from the internal radial face of the support, is in contact with a contact face of the guiding head that is orientated radially outward from same, the guiding head abutting against the peripheral surface of the support.

摘要： An axial flux machine is provided with an integrated clutch assembly, which is housed within the bore of an annulus-shaped stator of the machine. First and second rotors, located either side of the stator are attached to the clutch basket of the clutch assembly, and rotate in unison relative to the stator. A machine housing is provided between the stator and an engagement face of the clutch basket, seated on bearings between the clutch basket and machine housing, to provide a rigid structure.

摘要： A rotor (10) of an electric machine has a shaft (11) a laminated core (12) arranged on the shaft (11) and balancing bodies (13) arranged on the shaft (11). The balancing bodies (13) have an aperture (15) situated outside the center of gravity. Each balancing body (13) is mounted by way of the aperture (15) on the shaft (11) of the rotor (10) in a defined angular position. Positioning sleeves (20) are arranged on the shaft (11) to define a distance between bearings (16, 17) of the shaft (11) and the laminated core (12) or the balancing bodies (13) and to provide an anti-rotational safeguard for the balancing bodies (13).

摘要： Disclosed herein is a method for forming a rotor or stator core. The method includes the steps of: providing a plurality of key punches disposed about an inner diameter area of a sheet of electrical steel and circumferentially spaced from one another and activating a first key punch of the plurality of key punches to cut the electrical steel sheet to remove a portion to form a first key disposed at a first key rotational angle from the line of orientation from a plurality of key rotational angles.
