Abstract

846,196. Electric motors. MINITONE Inc. Sept. 2, 1958 [Sept. 12, 1957], No. 28106/58. Class 35. A miniature motor 10 comprising field magnet 12 of barium ferrite and armature 13 housed within body 11 has coil springs 40, 41 to bias silver-graphite brushes 36, 37 against commutator 24 and studs 50 extending longitudinally through the motor to form, with washers 55 and nuts 56, common fastenings for the motor parts. Field magnet 12 magnetized from its inner to its outer surface is sufficiently strong to support the armature when the motor is vertical and to cause it to be self-centring when horizontal. Housing 11 comprises end brackets 15, 16 of insulating material and central steel section 14 which completes the magnet circuit formed by armature and field magnet. Bearing cups 28, 33 on the end brackets hold resilient ring members 29, 31 and bearings 30, 32 to provide alignment for the armature. Contacts 42, 43 have end portions 46 to contact the brushes via the springs and central portions 44 which are held against the face of bracket 15 by insulating member 47. In addition a non-magnetic shim may be placed between field magnet 12 and end bracket 16 to free the shaft bearings from end thrust due to the weight of the motor (Fig. 1, not shown).
