DEFINITION

Classification: 318/3

(under the class definition) Subject matter in which one or more electric motors are connected or arranged to be

connected to actuate one or more particular or specific load devices which load devices must constitute a significant part of the combination; and in which means are also provided for controlling or supplying electric energy to the electric motor or motors.

(1) Note. See Load Device Driven By The Motor, in the Class Definition for a statement in regard to the combination of electric motors and load devices driven thereby included to this class.

(2) Note. Significant power, torque, force or motion transmitting mechanism is considered to be a particular or specific load device for classification in this or the indented subclasses. See Motor Systems and Power, Motion, Force or Torque Transmitting Devices Driven Thereby, in the Class Definition for the combinations of motor supply and/or control and the power, torque, force or motion transmitting mechanism driven thereby which are included in this class.

(3) Note. Where the particular load device is a flywheel merely, classification is not herein but in appropriate subclasses below. See the Search notes below.

(4) Note. See the classes listed under the class definition.

SEE OR SEARCH THIS CLASS, SUBCLASS: 39, for electric motor systems of the work and feed or indexing type of motor combination where there are a plurality of motors.

161, for an electric motor driving a flywheel, see (2) Note above.
