CONTROL OR REGULATION OF ELECTRIC MOTORS, ELECTRIC GENERATORS OR DYNAMO-ELECTRIC CONVERTERS

**Definition:** This place covers:

Arrangements for

or otherwise controlling:

**Limiting references (this place does not cover):** - Arrangements for merely turning on an electric motor to drive a machine or device, e.g.: vacuum cleaner, vehicle starter motor -> A47L9/28 , F02N11/00 - Arrangements for controlling electric generators for charging batteries -> H02J7/00 - Arrangements for starting, regulating, electronically commutating, braking, or otherwise controlling electric machines not otherwise provided for, e.g. machines using piezoelectric effects -> H02N

**Glossary:** - control: means influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation - regulation: means maintaining a variable automatically at a desired value or within a desired range of values, in which the variable is detected in the system and fed back for determining its deviation from the desired value. The determined deviation is used by the means for maintaining the variable to its desired value or values. Regulation is a form of "control".
