| | Class Definition for Class 318 - ELECTRICITY: MOTIVE POWER SYSTEMS |
 | | However, note that subclass 39 of Class 318 provides for work and feed or indexing combinations, that is, motor systems having two motors, one motor driving the work and tool with respect to each other, and the other motor driving the means for positioning or feeding the tool with respect to the work. |
 | | The nominal combination of an "electric motor" and a particular brake or braking system for braking the electric motor, in which combination no details of structure of the electric motor or no electric motor circuit relationships are set forth in the claim, is classified in Classes 188 and 303. |
 | | The line between Class 192, subclasses 1.1+, motor control and brake control, and Class 318 is as follows: Where there is any control of the electric motor combined with additional means for braking the motor wherein the motor is always braked whenever the braking means is rendered effective, classification is in Class 318. |
