Abstract:
A salient pole machine and method of forming the same comprising a rotating field assembly and at least one inter-pole cap connected to the rotating field assembly and/or at least end coil cap connected to the rotating field assembly. Each inter-pole cap preferably includes a top surface that has a curvature and/or at least one cavity. Each end coil cap may include at least one support. The salient pole machine may also include at least one fan assembly independent of the rotating field assembly. In a preferred embodiment, the salient pole machine includes at least one mounting plate, wherein each fan assembly is mounted on the mounting plate. The inter-pole caps and the end coil caps preferably comprise composites, polymers, alloys, ceramics, or naturally occurring materials.
Abstract:
An electric motor is provided. A rotor sensor mechanism is operable to sense a condition of the rotor. The rotor sensor mechanism includes a target component, a radial sensor, and a sensor carrier. The target component comprises a shutter wheel fixed relative to the rotor for rotational movement therewith. The shutter wheel includes a plurality of circumferentially spaced, radially projecting radial target teeth. The radial sensor is configured to sense the target teeth. The radial sensor is at least generally axially aligned with the radial target teeth and faces radially toward the radial target teeth. The sensor carrier adjustably supports the radial sensor on the motor frame assembly so as to permit the radial sensor to be selectively positioned relative to the radial target teeth.
Abstract:
A rotor assembly for an electric machine includes a core having at least one post and a cap wherein electrical windings are wound about the rotor assembly to define a pole. The rotation of the rotor and rotor pole relative to a stator generates a current supplied from the electric machine to a power consuming device.
Abstract:
A synchronous reluctance machine (SynRM) comprises a rotor having a plurality of rotor disks 110 with longitudinal flux barriers 130. When the rotor disks 110 are stacked together to form a rotor core 100, the flux barriers 130 define channels 140 extending in an axial direction of the rotor core 100. Air is forced to flow through these channels 140 in order to improve a temperature distribution within the machine.
Abstract:
A coil support wedge for a high speed generator with salient pole rotor is integrally constructed and includes a plurality of fluid passageways. Because it is integrally formed, the support wedge is substantially fluid tight. Thus, it is less susceptible to cooling fluid leakage from the fluid passageways, which increases the overall reliability of the generator into which the wedge is installed.
Abstract:
The heat radiating properties of the coil end sections of a stator are improved. The coil end sections (54 and 55) are arranged near the outer peripheral sides of cooling fans (33 and 34) and the coil ends on an outer shell side are brought into contact with frames (11 and 12) through an insulating film (10a). In the sections (54 and 55), a plurality of coil ends are arranged apart from each other except their root sections so that the ventilation resistances in the sections (54 and 55) can become lower than those around the sections (54 and 55). Therefore, a high heat radiating property is obtained, because most of a cooling wind passes through the sections (54 and 55) and comes into collision with almost all coil ends.
