This disclosure relates to an electric transmitter for sewing machines and like machines which provides a greater revolution rate than that normally possible solely with an alternating current transmitter in the absence of gearing and like speed multipliers. The electric transmitter utilizes a plurality of motors serially connected with the motors being mounted in a single housing whereby the electric transmitter may be mounted in the normal manner and the clutch-brake thereof may remain of the conventional construction and be mechanically operative.
