Abstract

744,948. Electric motors. BOSCH GES., R. Sept. 15, 1953 (Sept. 18, 1952], No. 25412/53. Class 35. [Also in Group XXII] The stator core of the motor of a handsupported tool is carried by a pot-shaped insulating member secured in an outer metallic casing. As shown, metal casing members 13, 14, 15 are insulated from live parts by the provision of insulating members 20, 32 of which the latter carries the stator core 12, the brushholders and bearing 28 while member 32 houses bearing 31 and one end of countershaft 36 which carries a gear-wheel 42 of insulating material. There may be gaps between members 20 and 13, also 20 and 12 over part of their circumferences. In a modification the closed end of the potshaped insulating member carrying the stator core is at the gearing end.
