It is definitely a motor.
Weeden Made 15 different electric motors.
Weeden No. 1; 101; 102; 103; 104; 105; 106; 107; 109; 110; 111; 112; 112-114; and 117.
I believe that this one is a Weeden No. 101 (the replacement for the Weeden No. 1). It was produced from 1912-1918. Flywheel is 2 1/2" in diamater, base is 6" x 4".
