摘要:
A bulk material formed on a surface, the bulk material including a plurality of adhered domains of metal material, substantially all of the domains of the plurality of domains of metal material separated by a predetermined layer of high resistivity insulating material. A first portion of the plurality of domains forms a surface. A second portion of the plurality of domains includes successive domains of metal material progressing from the first portion. Substantially all of the domains in the successive domains each include a first surface and a second surface, the first surface opposing the second surface, the second surface conforming to a shape of progressed domains, and a majority of the domains in the successive domains in the second portion having the first surface comprising a substantially convex surface and the second surface comprising one or more substantially concave surfaces.
摘要:
A system for forming a soft magnetic bulk material of a motor stator from a magnetic material and a source of insulating material, the system comprising: a support; a heating device; a deposition device; and an indexing mask subsystem. The support is configured to support the soft magnetic bulk material of the motor stator. The heating device is for heating the magnetic material to form particles having a softened state. The deposition device is for depositing successive layers of particles of the magnetic material in the softened state on the support. The indexing mask subsystem is configured as a first negative of an inner shape of the motor stator and a second negative of an outer shape of the motor stator. The indexing mask subsystem is located between the deposition device and the support and indexed relative to the support upon deposition of the successive layers to selectively block the successive layers of particles of the magnetic material in the softened state from being deposited on the support, thus forming the soft magnetic bulk material of the motor stator as the inner shape of the motor stator and the outer shape of the motor stator on the support. The soft magnetic bulk material has a plurality of adhered domains of magnetic material, wherein substantially all of the domains of magnetic material are separated by a predetermined layer of high resistivity insulating material.
摘要:
A system for forming a soft magnetic bulk material of a predetermined shape from a magnetic material and a source of insulating material. The systems has a heating device; a deposition device; a support configured to support the soft magnetic bulk material of the predetermined shape; and a mask configured as a negative of at least a portion of the predetermined shape. The heating device heats the magnetic material to form particles having a softened state and wherein the deposition device deposits successive layers of particles of the magnetic material in the softened state on the support with the mask located between the deposition device and the support. The mask is indexed to a position relative to the support upon deposition of the successive layers. The mask selectively blocks the successive layers of particles of the magnetic material in the softened state from being deposited on the support forming the soft magnetic bulk material of a predetermined shape on the support.

A motor comprises a stator comprising at least one core; a coil wound on the at least one core of the stator; a rotor having a rotor pole and being rotatably mounted relative to the stator; and at least one magnet disposed between the rotor and the stator. The at least one core comprises a composite material defined by iron-containing particles having an alumina layer disposed thereon.
