Small electrical motor for use in e.g. actuator in motor car, has solid ring whose outer diameter is smaller than internal diameter of corresponding protrusion parts, where solid ring is connected with protrusion parts by welded joint

摘要

The motor has metallic protrusion parts (2.1, 3.1) receiving bearings (2.2, 3.2) and formed at end surfaces of stationary components (2). One of the bearings is designed as a slide bearing made of sinter material and inserted in a solid ring (2.3) made of weldable material. Outer diameter of the ring is smaller than internal diameter of the corresponding protrusion parts. The solid ring is connected with the protrusion parts by a welded joint, where welding between the ring and protrusion parts is taken place on a contact edge of the ring and protrusion parts. An independent claim is also included for a method for manufacturing a small electrical motor.
