A method for recycling at least one magnet of an electric machine. A subassembly having the magnet is disassembled from the electric machine. In the process, the following steps are provided: carrying out a first thermal treatment of the subassembly at a first temperature, mechanical separation of the magnet from the subassembly, and carrying out a second thermal treatment of the magnet at a second temperature, which is higher than the first temperature, for debinding and/or cleaning of the magnet.

A system and method for servicing a generator rotor of a turbine are presented. The system includes a support device for supporting the rotor. The support device has a surface. A contact point is established on the surface where the rotor contacts the surface. A location of the contact point along the surface may be variable based on a diameter of the rotor. The support device may be able to accommodate a plurality of different rotors having a plurality of different diameters.

A system for assembling a generator, preferably a permanently excited generator of a wind turbine, comprising a rotor and a stator. A vertical assembly device connectable to the rotor and the stator is proposed, for guiding the rotor in parallel and coaxially aligned to the stator during assembly, the vertical assembly device comprising a first assembly element being connectable to the rotor, a second assembly element being connectable to the stator, and guiding means for guiding the first assembly element coaxially aligned to the second assembly element.

In a method for producing an individual-segment rotor for an electric machine, a shaft is arranged in a mold and a plurality of laminated core segments, which are at a distance from one another, are arranged on the circumference of the shaft in a distributed manner in the mold. The laminated core segments each have a fixing contour for a form closure for radially fixing the laminated core segment on the shaft. In addition, a permanent magnet is arranged between each pair of laminated core segments. An intermediate space between the shaft and each fixing contour of the laminated core segments is filled with a curable nonmagnetic material. The curable nonmagnetic material forms a form closure with respect to the radial direction with each fixing contour, and therefore each laminated core segment is retained on the shaft by the form closure.

Methods and devices are provided that allow for easy replacement of a motor assembly in a fuel dispensing unit. In one embodiment, a protective end cap for use with a motor assembly is provided and includes a junction box housing having a sealed end that can couple to a motor, and an opposite open end that can couple to an end plate. The junction box housing can be configured to house a junction box that allows electrical wires extending through the end plate to couple to electrical wires extending from the motor through the sealed end of the junction box housing. A motor assembly having a junction box housing and methods for replacing a motor assembly in a fuel dispenser are also provided.

A placement and replacement system and method for placing and replacing the electrical components of electromagnetic rotary machine, wherein the system comprises a frame, multiple of system fixing means to attach the system to the electromagnetic rotary machine, moving means for inserting electrical components to the electromagnetic rotary machine and extracting the electrical components from the electromagnetic rotary machine to place or replace the electrical components.

A liquid-cooled motor may include a removable liquid cooling jacket. The jacket may enclose a commercial off-the-shelf electric motor. The jacket may be ribbed and may include multiple fluid channels, allowing fluid to circulate over the surface of the electric motor and limiting eddy currents. A front-most portion of the liquid-cooled motor may include electrical and fluid interfaces, including an inlet and an outlet for tubing to carry fluids. Removable gaskets or O-rings may be placed between the front-most portion and the jacket, and between a rear-most portion and the jacket. The jacket may be connected to the front-most portion and the rear-most portion using removable screws. The liquid-cooled motor may be disassembled for maintenance and then re-assembled. The jacket, front-most portion, and rear-most portion may be 3D printed from a watertight acrylic polymer, or machined from an engineering thermoplastic.

Embodiments herein provide an electrical machine comprising a stator with a stator winding arrangement, a rotor arranged for rotation inside the stator, a machine housing for housing the stator, at least one temperature sensor arrangement and wherein a sensor-end of the temperature sensor is arranged for insertion into the immersion sleeve and for insertion through an insertion bore arranged in an opening in the machine housing, so that the sensor-end of the temperature sensor is positioned within a cooling slot of the stator windings, when inserted, so as to allow sensing of a temperature of measure of temperature of the stator windings by electric connection to the wire-end of the temperature sensor.

An electromechanical flywheel machine includes a flywheel mass and a motor-generator having a rotor rotatable about a stationary inner stator having stator windings.

A method for laterally moving an industrial machine is provided. The method may include: supporting the industrial machine on a pair of rail elements configured to be positioned laterally below and support the industrial machine, the rail elements allowing the industrial machine to be moved laterally from a first operative position to a second, maintenance position. A pair of linear actuators configured to laterally move the industrial machine from the first, operative position to the second, maintenance position.
