초록 ▼

A modular, expandable, low-weight electric motor has a cylindrical, non-magnetic casing formed in axially-aligned sections. The casing sections are releasably connected to define a unitary structure with a polygonal exterior surface and a circular interior surface. Separate U-shaped stator pole assemblies are releasably mounted against the exterior of the casing, each casing section carrying the poles associated with a different motor phase. The poles extend through apertures into the interior of the casing, and have active pole faces which are curved and substantially flush with the circular interior surface of the casing. A modular rotor is mounted in the interior of the casing and carries magnetic elements in axially spaced-apart sets corresponding to each motor phase. The active faces of the magnetic elements are curved and oriented in a cylindrical arrangement. During each rotation of the rotor, the pole faces of each motor phase simultaneously and repeatedly register with the associated magnetic element faces forming air gaps, and the magnetic elements simultaneously complete local magnetic circuits with each stator pole assembly. The sets of magnetic rotor elements are indexed circumferentially relative to one another such that the motor is self-starting.

In an electric motor comprising a casing having a central longitudinal axis and an interior, a rotor in the interior of the casing, and means supporting the rotor for rotation about the axis relative to the casing, the improvement in which: the motor comprises a multiplicity of axially-aligned motor phases, each of the motor phases comprising: A. a multiplicity of stator pole assemblies, each of the stator pole assemblies comprising a plurality of magnetically-coupled stator poles each having a pole face and comprising electrically-operable coil means for producing a magnetic field in each of the stator poles of the stator pole assembly; B. means for releasably mounting each of the stator pole assemblies to the casing with the coil means of the stator pole assembly external to the casing and with the poles of the stator pole assembly extending into the interior of the casing through one or more apertures in the casing, the stator pole assemblies being spaced-apart circumferentially about the exterior surface of the casing with the pole faces of the stator pole assemblies oriented in a cylindrical arrangement with a predetermined radius; and, C. a multiplicity of magnetic elements mounted to the rotor and circumferentially spaced-apart, each of the magnetic elements having an element face, the element faces of the magnetic elements being oriented in a cylindrical arrangement with a radius smaller by a predetermined amount than the radius of the cylindrical arrangement of the pole faces of the stator pole assemblies, the element faces of the magnetic elements and the poles faces of the stator poles assemblies being arranged such that, during each rotation of the rotor, the poles faces of the stator pole assemblies simultaneously and repeatedly register with the element faces of the magnetic elements to form at each of the pole faces of the stator pole assemblies an air gap having a radial dimension corresponding to the predetermined amount and such the magnetic elements complete a local magnetic circuit with each of the stator pole assemblies whenever the air gaps are formed, the local magnetic circuit completed with each of the stator pole assemblies comprising the stator poles of the stator pole assembly, the air gaps formed at the pole faces of the stator pole assembly, and one or more of the magnetic elements which define the air gaps with the pole faces of the stator pole assembly; the magnetic elements and stator poles assemblies of the motor phases being circumferentially oriented such that, at any time, at least one of the motor phases is capable of generating a torque to rotate the rotor when the coil means of the stator pole assemblies of the least one motor phase are electrically-energized.
