The shaft includes at least one slit recessed radially inward from an outer peripheral surface of the shaft and extending along the axial direction. A portion of the at least one slit is radially inside the annular portion. A lead wire of the coil is accommodated in the at least one slit. | 2022-07-21 |
20220231564 | MOTOR INCLUDING SEALING STRUCTURE - A motor includes a motor main body including a rotor and a stator, a housing that houses the motor main body, a controller that is located above the motor main body o controls rotation of the rotor, and a cover that surrounds the controller from a radially outer side. The housing includes a cover joint that is annular and surrounds the controller when viewed in an axial direction. The cover includes a cylindrical portion that surrounds the cover joint from an outside in a radial direction. The cover joint includes a contact portion that contacts a surface of the cylindrical portion in the radial direction and an adhesive joint that is bonded with the cylindrical portion via an adhesive in the radial direction. The contact portion and the adhesive joint are adjacent each other in a circumferential direction. | 2022-07-21 |
20220231565 | INTEGRATED MAGNETIC SHIELD AND BEARING HOLDER - An integrated magnetic shield and bearing holder useable with electric motors includes a shaft portion and a cover portion extending radially outward from the shaft portion. The shaft portion includes an inner wall defining a channel and a ledge extending radially inward from the inner wall. The cover portion includes a first layer, a second layer extending substantially parallel to the first layer, a magnetic shield extending between the first layer and the second layer, and an outer wall extending from the first layer and/or the second layer such that a space is defined between the outer wall and the shaft portion. The cover portion includes one or more retainers coupled to the magnetic shield to restrict movement of the magnetic shield relative to the first layer and/or the second layer. | 2022-07-21 |
20220231566 | AIR-COOLING SYSTEM FOR PORTABLE GENERATOR - Devices, systems, and methods to air-cool a portable generator are disclosed. The devices include various air ducts to direct airflow over heated components within a cabinet of the portable generator to cool the components by convection. A damping fan draws ambient temperature air into the cabinet and directs the air into channels of an outflow duct. | 2022-07-21 |
