Abstract: There are disclosed winding configurations for electric machines that employ printed circuit board (PCB) type end winding connections to enable an automatic and faster assembly of the electric machines. The winding configurations provide a compact PCB-type end winding arrangement with an optimal fewer number of turns/bars in the slots of the board to complete the loop of winding connections. The winding configurations have application in three phase or multiple phase inner rotor or outer rotor electric machine topologies.

Abstract: A sliding contact assembly for a DC electrical outlet receives plug contacts of an electrical plug. The assembly includes sliding contact structure having a base and a plurality of electrical sliding contacts fixed to the base. A housing includes a first end wall having an internal top surface and second end wall opposing the first end wall. The second end wall has an internal bottom surface. The housing has a side wall structure defining an internal chamber between the top surface and the bottom surface. The sliding contact structure is disposed in the housing to be movable linearly within the chamber. A spring is disposed between the top surface of the housing and a surface of the base so that when the plug contacts are completely disconnected from the associated sliding contacts, the spring rapidly forces the sliding contacts away from the plug contacts, reducing arcing energy there-between.

Abstract: A self-contained actuator for use in a robot manipulator includes: a housing, in which are arranged in axial sequence a gear, a motor, a brake, a sensor and a motor drive. The motor drive includes wide-bandgap/WBG electronics and is arranged in heat-dissipating relationship with a free end of the housing. Through the motor and some further components, there is provided a central channel for receiving a cable connected to at least one further actuator of the robot manipulator. The channel may be angled or straight. In embodiments where the motor drive is hollow, the central channel extends between the axial ends of the actuator. There is further provided an all-in-one industrial robot comprising a robot manipulator, in which one or more self-contained actuators with the above characteristics are installed and a robot controller is physically integrated.

Abstract: A device may include a first end, a second end, and a coupler configured to extend through an aperture from a first side to a second side of a motor cover. The coupler includes a head portion, a conduit portion extending from the head portion towards the second end, and a first bore axially extending through the coupler. The device may include a brush holder extending through the first bore. The brush holder includes a cylindrical body, a socket at the first end, and a receptacle at the second end. The device may include a first lock nut including a first threaded bore axially extending through the nut. The device may be configured to enable a grounding brush to contact a motor shaft to provide a current discharge path to ground to reduce an erosion of the motor components including the motor shaft and rolling bearing elements.

Abstract: A method of estimating an operating parameter of industrial mechanical power transmission equipment is provided. The method includes acquiring data of a first parameter of the gearbox using a sensor, inferring a second parameter of a gearbox based on the acquired data of the first parameter by using a machine learning model, wherein the second parameter is of a different type from the first parameter and includes at least one of a torque of the gearbox, a rotational speed of the gearbox, or an overhung shaft force of the gearbox, and outputting the estimated second parameter.

Abstract: An electrical motor is provided to reduce torque ripple. Torque ripple is a variation in torque output as the rotor rotates. The motor has a stator and a rotor. The stator slots are used for windings. The rotor slots define a plurality of poles. The number of slots in the stator are equal to the number of slots in the rotor.

Abstract: The present disclosure relates to electrical machines, such as liquid-cooled motors. The liquid-cooled motors can include a stator with cooling tube channels (e.g., corrugated channels) having tubes inserted and expanded. Lamination holes for each lamination in the lamination stack of the stator can have varying diameter along the axial direction to achieve a corrugated internal feature. The tubes for cooling liquid can be fitted in the lamination holes of the stator. In some embodiments, hydraulic expansion expands and plastically deforms the tubes to the contour of the corrugated internal feature of the corrugated channel. In some embodiments, the tube can also be inserted in the corrugated channel and a stator head plate, thereby helping create a compact stator by removing the need for tube connections to connect the corrugated channels.
