Abstract
In an electric motor comprising permanent magnets in the form of ferrite blocks, the blocks are mounted on the motor frame by elements developing elastic forces in three mutually orthogonal directions, one of which is that of the motor axis. As shown in Fig. 8, resilient U- shaped strip metal elements 156 apply axial forces on the ferrite blocks 155, 158 through resilient tongues 152, 1521, 153, 1531, radial force through resilient tongues 144, 145 and circumferential forces through the parts 200. The resilient mounting elements 156 are axially located in the frame by resilient tongues 127, 128 and circumferentially located by a part 154 engaging an axial rib N in the frame 101. In a modification, Figs. 14-19 (not shown) the mounting elements are made of plastics material. In assembling the motor, the ferrite blocks are attached by magnetic attraction to a rotor, the rotor and a brush holder 179, Fig. 20 are then placed in the lower of two semi-cylindrical stator portions 170, 171, mounting elements 181 are placed on the stator portions and these portions are then secured together using end plates 174 carrying bearings 175 for the rotor. The resilience of the mounting elements removes the ferrite blocks from the rotor and presses them against the stator frame. In a modification, Fig. 21 (not shown) end plate portions are formed integrally with the two stator portions and the latter are secured together using circlips (191).
