A method for inserting conductive pins from a transfer device to a body of a wound part in order to form an electrical winding of a wound part of a rotary electric machine. The method includes a preparation step, in which the conductive pins are arranged in the spindle body, and a step of positioning the spindle body relative to the body of the wound part. A guide step arranges a guide device to guide the conductive segments in a circumferential and/or radial direction, and a transfer step inserts conductive segments into the corresponding slots.

An assembly and insertion system for assembling and inserting, into a stator pack, a winding having one or more layers of basic conductors is provided. The assembly and insertion system has a circumferential containment of the basic conductors with a set of spaces or slots, and one or more removable inserters of the basic conductors into the circumferential containment, and elements for rotating the circumferential containment about the winding axis. A rotary table is configured to rotate about a table axis to bring the circumferential containment from an assembly position to an insertion position for insertion into the stator pack. The winding is assembled on one side of the rotary table while feeding elements of the stator pack and relative introduction elements of the winding into the stator pack at the insertion position act on the opposite side. A process for assembling and inserting a winding into a stator pack is also provided.

Methods of designing downhole drilling motors are disclosed herein. The method is iterative, allowing for a custom drilling motor to be designed based on client and application specific needs.

A permanent magnet rotor can include a rotor body and at least one magnet. The rotor body can include at least one rotor cavity.

A stacked core is formed by stacking a plurality of first core sheets and second core sheets stamped from an electromagnetic steel sheet. Each first core sheet is formed such that a sheet thickness thereof increases from one side toward another side. Each second core sheet is formed such that a sheet thickness thereof increases from the other side toward the one side. The first core sheets and the second core sheets are alternately stacked per predetermined number of sheets.

A rotating electrical machine wiring component has a wire shape and is configured to be connected to a plurality of ends of an armature winding aligned in parallel in a predetermined alignment direction. The rotating electrical machine wiring component includes a weld portion that is provided at one longitudinal end and is connected to the plurality of ends of the armature winding by welding, wherein the weld portion extends in an extending direction along the alignment direction, and wherein the weld portion comprises protrusions that protrude respectively along the plurality of ends of the armature winding.

A rotor of an electric machine is provided. The rotor includes a plurality of laminates arranged along an axial direction, the plurality of laminates including a first laminate having: a body formed of a first material, the first material being a ferromagnetic material; and a structural element formed integrally with the body of a second material, the second material being a non-ferromagnetic material.

An electric motor which includes a stator with an outer perimeter provided with beams and a stator frame surrounding the stator and including at least two intermediate plates having openings for receiving the stator. For enabling simplified assembly of the electric motor, the intermediate plates include first contact surfaces forming a tight contact with corresponding second contact surfaces provided on the beams. The electric motor is provided with bolts extending through the intermediate plates between the outside of the stator frame and the openings at an exactly predetermined position of each of the first contact surfaces and engaging threaded holes provided to an exactly predetermined position of each of the second contact surfaces.

In a method for producing a laminated core (1) of an electric machine, sheet metal laminations (4, 5), which are based on an iron material, are alloyed by means of heat treatment with an alloy material (16) comprising silicon. Before the heat treatment, aluminum-based foil laminations (6, 7) which comprise foil aluminum oxide layers (8, 9) and are each at least partially coated with the alloy material, are arranged between the sheet metal laminations (4, 5).

A manufacturing method of a field magnet device includes: an assembling process that includes assembling a plurality of magnets, which are prior to magnetization, to a magnetizer; a first magnetizing process that includes generating a magnetizing magnetic field from the magnetizer and magnetizing all of the magnets arranged in a circular ring form by using the magnetizing magnetic field; and a second magnetizing process that is executed after the first magnetizing process and includes generating a magnetizing magnetic field, which is stronger than the magnetizing magnetic field generated in the first magnetizing process, from the magnetizer, and sequentially magnetizing all of the magnets by using the magnetizing magnetic field generated in the second magnetizing process such that a predetermined number of magnets continuously arranged in a circumferential direction among the magnets are magnetized each time.
