Abstract

945,358. Electric motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 2, 1961 [June 15, 1960], No. 21038/60. Heading H2A. [Also in Division F2] An electric motor has at each end of its rotor an axially facing annular cam each engaging a cam on the shaft so that limited axial movement of the rotor takes place when the rotor rotates relative to the stator. Fig. 1 shows an induction motor having a rotor support 6 rotatably mounted on its shaft. Cam surfaces 7 (Fig. 3) are formed at each end of the support and these engage cams 8 pinned to the shaft so that when over-run of the shaft occurs when the motor is switched off the rotor moves downwardly of the drawing. This brings a friction surface 11 mounted on the end 10 of the rotor support into contact with a stationary disc 12 to brake the rotary movement. A spring may be provided to urge the rotor in the direction which brings the friction surfaces into contact (Fig. 2, not shown). Specification 903,197 is referred to.
