AsynchronousMachine

A rotating machine whose shaft rotates asynchronously with the electrical field. Also known as an induction machine with no external connection to the rotor windings, e.g. squirrel-cage induction machine.

Inheritance

Attributes

Name URI Cardinality and Range Inheritance Description
converterFedDrive cim:AsynchronousMachine.converterFedDrive 1..1 boolean direct Indicates whether the machine is a converter fed drive. Used for short circuit data exchange according to IEC 60909.
efficiency cim:AsynchronousMachine.efficiency 1..1 PerCent direct Efficiency of the asynchronous machine at nominal operation as a percentage. Indicator for converter drive motors. Used for short circuit data exchange according to IEC 60909.
iaIrRatio cim:AsynchronousMachine.iaIrRatio 1..1 float direct Ratio of locked-rotor current to the rated current of the motor (Ia/Ir). Used for short circuit data exchange according to IEC 60909.
polePairNumber cim:AsynchronousMachine.polePairNumber 1..1 integer direct Number of pole pairs of stator. Used for short circuit data exchange according to IEC 60909.
ratedMechanicalPower cim:AsynchronousMachine.ratedMechanicalPower 1..1 ActivePower direct Rated mechanical power (Pr in IEC 60909-0). Used for short circuit data exchange according to IEC 60909.
reversible cim:AsynchronousMachine.reversible 1..1 boolean direct Indicates for converter drive motors if the power can be reversible. Used for short circuit data exchange according to IEC 60909.
rxLockedRotorRatio cim:AsynchronousMachine.rxLockedRotorRatio 0..1 float direct Locked rotor ratio (R/X). Used for short circuit data exchange according to IEC 60909.
mRID cim:IdentifiedObject.mRID 1..1 string IdentifiedObject Master resource identifier issued by a model authority. The mRID is unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended.For CIMXML data files in RDF syntax conforming to IEC 61970-552, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements.
