class Ifc4::IfcElectricMotor : public Ifc4::IfcEnergyConversionDevice

An electric motor is an engine that is a machine for converting electrical energy into mechanical energy.

HISTORY New entity in IFC2x4

Type Use Definition IfcElectricMotor defines the occurrence of any electric motor; common information about electric motor types is handled by IfcElectricMotorType. The IfcElectricMotorType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcElectricMotorType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcElectricMotorType has ports or aggregated elements, such objects are reflected at the IfcElectricMotor occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcElectricMotorType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcElectricMotorType.HasPropertySets. If both are given, then the properties directly defined at IfcElectricMotor override the properties defined at IfcElectricMotorType. Refer to the documentation at the supertype IfcEnergyConversionDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ElectricMotorTypeCommon (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.

Qto_ElectricMotorBaseQuantities

Material Use Definition The material of the IfcElectricMotor is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcElectricMotorType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

Casing: Material from which the casing is constructed.

Port Use Definition The distribution ports relating to the IfcElectricMotor are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the electric motor occurrence is defined by IfcElectricMotorType, then the port occurrences must reflect those defined at the IfcElectricMotorType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcElectricMotor PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

Line (ELECTRICAL, SINK): Receives electrical power. Drive (NOTDEFINED, SOURCE): Motor connection to a driven device.
