  • Method of making an external rotor gyroscope
    Patent number: 4366615
    Abstract: An external rotor comprises an annular case within which is the laminated stack forming the motor drive members and end members at each side of the stack. These are heat fitted together to form an annular blank which is then machined to form an axial bore therein and end faces normal to the bore. A stator laminated stack is heat fitted onto an axle and thereafter peripherally machined and bearing seats are machined on the ends of the axle. After the stator is inserted into the rotor bore, bearings are mounted on the ends of the axle and preloaded by tightening nuts onto the axle ends and against the bearings. The bearings comprise inner rings seated directly on the axle and outer rings seated directly on the inside and end faces of the rotor.
