Abstract: A method of monitoring a magnetic orientation of a composite magnetic material injected into a rotor pole of a rotor core. The rotor pole is defined by at least one rotor cavity. The method includes injecting a magnetic composite material into the at least one rotor cavity defining the rotor pole and applying an external magnetic field to the rotor pole to magnetically orient the magnetic composite material during injection into the at least one rotor cavity.

Abstract: A rotor of a synchronous reluctance motor may include: a plurality of laminations forming a stack, each lamination including: two parallel surfaces and a perimeter that define the lamination and a direction of stacking the laminations that is perpendicular to the parallel surfaces, the lamination at least partially filled with a magnetically soft electrical conductor and at least one cavity encircled by the conductor and extending from a first to a second surface of the two parallel surfaces, the conductor forming at least one bridge at the perimeter of the lamination from one side of the at least one cavity to another side of the at least one cavity. A value of a magnetic property and a value of a mechanical property of the at least one bridge differs from a value of the magnetic property and a value of the mechanical property of the conductor material.

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 method for operating an electrical machine having a stator and having a rotor with permanent magnets, includes: running the electrical machine; determining, while performing the running of the electrical machine, whether the permanent magnets have been demagnetized; finding, while running the electrical machine, the q-axis responsive to a determination that the permanent magnets have been demagnetized; firing a current pulse through the stator, while running the electrical machine, when the q-axis reaches a desired position relative to a selected stator phase, wherein the current pulse is constructed to remagnetize the permanent magnets; and continuing to run the electrical machine.

Abstract: A permanent magnet motor is provided that produces variable magnetic flux. The motor may include two different types of permanent magnets with different coercivities. The magnetic state of one of the magnets may be altered during use. In one state, the effective magnetic flux of the motor is greater, and in another state, the effective magnetic flux of the motor is less.
