NSN 664221PC2

An item which is an electrical rotating machine combining both control motor and tachometer generator action. The control motor and tachometer generator may be contained in the same or separate housings. It is designed for servo application where instant response to input signal is essential. It is generally used in circuits where the output potential from the tachometer generator is fed back to prevent excessive oscillation and for assuring high stability in a servo loop. Excludes:dynamotor; and motor-generator.

40.0 single section ambient temp in deg celsius per section at full rated power, single shaft actuator type, stops actuator travel control feature, 85.0 single section ambient temp in deg celsius per section at zero percent rated power, ball shaft bearing type.
