(under the class definition) Subject matter in which the motor is a noncommutating electric motor and comprises a magnetic-field producing means combined with one or more electric conductors mounted to move relative to and in proximity to the field-producing means, said field-producing means being so constructed and/or energized that the magnetic field produced thereby is, at any instant of time, of the same polarity or direction throughout its extent with reference to the path of travel of the movable electric conductor or conductors.
(1) Note. The motors in this subclass are known as "homopolar motors".
(2) Note. This subclass includes alternating current and direct current motors.
(3) Note. In the case of direct current field energization, the direction of the generated c.e.m.f. in the armature conductors is always unidirectional when the conductors move in a continuous direction.
