摘要:
An electric machine includes a stator having a stator core, rotor core and/or magnetic core comprising a plurality of slots. Each of the plurality of slots includes a spacer, a conductor, and encapsulated slot insulation. The spacer is configured to suspend the conductor away from the stator core by a dielectric distance without occupying all of the space between the conductor and the stator core. The encapsulated slot insulation includes an encapsulation material configured to flow in a liquid state around the perimeter of the conductor filling in the space between the conductor and the stator core. The encapsulation material cures to hold the spacer and the conductor in place. The encapsulated material typically has higher thermal conductivity properties than a conventional slot liner, increasing the performance of the motor.

An armature core (8A) includes a plurality of teeth (12) that radially extend. A plurality of coils (91), (92), and (93) are wound in a concentrated winding manner on a winding drum portion (12a) of each tooth; a winding wire (14) of a lowermost side of at least a first-layer coil is wound so as to come into close contact with a winding surface of a base end side of the winding drum portion; a second-layer coil, which is to be wound later, is wound so that at least a part of the second-layer coil overlaps the first-layer coil; and a step (12a1) as a regulating portion, which regulates the positional deviation of the winding wire of the lowermost side of the first-layer coil in an extending direction of the winding drum portion, is provided on at least a part of the winding surface for the first-layer coil on an outer periphery of the winding drum portion.

Dabei weist der Rotor (220) in einem Außenumfangsabschnitt (223) eine Mehrzahl von entlang einer Drehrichtung des Rotors (220) beabstandeten Nuten (222) auf. Hierbei weist zumindest eine Nut (222) bezüglich einer Umfangsoberfläche (226) des Rotors (220) einen Öffnungsquerschnitt (231, 237) auf, der sich von einem Öffnungsquerschnitt (231, 237) einer der Nut benachbarten Nut (222) unterscheidet.
摘要:
The depth from the open end of a rotor slot closest to a magnetic pole (6) of a rotary core (1) to a slot bottom or the bottom of a subslot (5) provided as a coolant ventilation path on a rotor slot bottom is made less than the depth of slots at and after a second slot counted from the magnetic pole (6) side in the direction of internal circumference, and when a shortest distance between the bottoms of the rotor slots (2) opposed to each other through a magnetic pole or a shortest distance between the bottoms of the subslots (5) is assumed to be a magnetic pole width of the slots, a magnetic pole width Wp1 of a slot closest to the magnetic pole side is set to 85% or more of a magnetic pole width Wp2 of a second slot counted from the magnetic pole side in the direction of internal circumference.

A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly 3002 may include a stator assembly with multiple coils in a distributed winding configuration. The stator assembly may have a central bore into which a rotor assembly having multiple poles is received and configured to rotate. A method of controlling a switched reluctance motor may include at least three phases wherein during each conduction period a first phase is energized with negative direction current, a second phase is energized with positive current and there is at least one non-energized phase. During each commutation period either the first phase or second phase switches off to a non-energized state and one of the non-energized phases switches on to an energized state with the same direction current as the first or second phase that was switched off. The switched reluctance motor may include a distributed winding configuration.

The present invention relates to a tubular body (100) for an electrical machine. The tubular body (100) comprises a curved surface area (101), a first tooth (110) and a second tooth (120). The tubular body (100) is arrangable with respect to a further tubular body (100) such that one of the tubular body (100) or the further tubular body (100) is rotatable with respect to the other one around a rotary axis (105). The first tooth (110) and the second tooth (120) extend from the curved surface area (101) along a radial direction (102) with respect to the rotary axis (105), wherein the first tooth (110) and the second tooth (120) are spaced apart from each other along a circumferential direction (103) around the rotary axis (105). The first tooth (110) comprises a first side wall (113) facing a second side wall (123) of the second tooth (120), wherein the first side wall (113) comprises a first section (111) which is parallel to the second side wall (123) such that a circumferential distance (104) between the first section (111) and the second side wall (123) is constant along the radial direction (102).
