IfcElectricMotorTypeEnum

Definition from IAI: The IfcElectricMotorTypeEnum defines the range of different types of electric motor that can be specified.

> HISTORY: New type in IFC 2x2

Enumeration

Value | Definition | Pset
DC | A motor using either generated or rectified D.C. power. |
INDUCTION | An alternating current motor in which the primary winding on one member (usually the stator) is connected to the power source and a secondary winding or a squirrel-cage secondary winding on the other member (usually the rotor) carries the induced current. There is no physical electrical connection to the secondary winding, its current is induced. |
POLYPHASE | A two or three-phase induction motor in which the windings, one for each phase, are evenly divided by the same number of electrical degrees. |
RELUCTANCESYNCHRONOUS | A synchronous motor with a special rotor design which directly lines the rotor up with the rotating magnetic field of the stator, allowing for no slip under load. |
SYNCHRONOUS | A motor that operates at a constant speed up to full load. The rotor speed is equal to the speed of the rotating magnetic field of the stator; there is no slip. |
