Abstract
A motor assembly comprises a composite housing having a core of sprayed magnetic particles and a winding on the core; and a rotor having a magnet located thereon, the rotor being rotatably mounted within the winding. The core of sprayed magnetic particles comprises particles of an iron-containing material that when deposited results in an aggregate of small micro-domains separated by insulation boundaries.
