Bipolar Electric Motor
A Landmark Important Historic French Trouve Bipolar Electric Motor, ca. 1881, by French Maker M. Trouve known for his electric motors, telegraph, telephone and communication devices. This famous French maker exhibited at the 1881 International Exhibition electric powered launches and was also experimenting with the application of the Trouve Motor for electric aerial propulsion of balloons. Reference is made to the Trouve Motor in Electricity and Magnetism as translated by Silvanus Thompson from the original French work of Anedee Guillemin. This motor is of the similiar design of Trouve Motors used for balloon propulsion and electric launch application, possibly is a prototype or exhibition model. The motor is in excellent running order having been tested on 12 volts DC and retains 98% of its original paint and patina. All brass parts are in original lacquer and there is no sign of wear. This unique motor incorporates a brass main motor frame which can be removed from the ornate base. There is a large thumb-screw which also allows for horizontal alignment of the driven sprocket and belt pulley. Details include a top mounted horizontal armature, segmented commutator with original multi-wire brushes, brass brush holders with top mounted terminals and knurled clamp-screws, armature shaft brass end adjustment screws, the main frame of brass with black paint engraved: Moteur Trouve Bte SGDG. #422. The armature with brass ends and 1/2" dia. drive gear makes contact with a 5 1/4" brass driven gear with cast and machined brass 4" dia. sprocket and 3" dia. round belt pulley. Overall length 11", width 5", height 9".
