class Ifc4x1::IfcMotorConnection : public Ifc4x1::IfcEnergyConversionDevice

A motor connection provides the means for connecting a motor as the driving device to the driven device.

HISTORY New entity in IFC2x4

Type Use Definition IfcMotorConnection defines the occurrence of any motor connection; common information about motor connection types is handled by IfcMotorConnectionType. The IfcMotorConnectionType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcMotorConnectionType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcMotorConnectionType has ports or aggregated elements, such objects are reflected at the IfcMotorConnection 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 IfcMotorConnectionType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcMotorConnectionType.HasPropertySets. If both are given, then the properties directly defined at IfcMotorConnection override the properties defined at IfcMotorConnectionType. 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_MotorConnectionTypeCommon (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.


Material Use Definition The material of the IfcMotorConnection 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 IfcMotorConnectionType, 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 IfcMotorConnection are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the motor connection occurrence is defined by IfcMotorConnectionType, then the port occurrences must reflect those defined at the IfcMotorConnectionType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcMotorConnection PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

Motor (NOTDEFINED, SINK): Connection from the motor. Drive (NOTDEFINED, SOURCE): Connection to the driven device.
