enum
Value
The IfcElectricMotorTypeEnum defines the range of different types of electric motor that can be specified. HISTORY: New type in IFC 2x2
Enumeration
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. USERDEFINED: User-defined type. NOTDEFINED: Undefined type.
