Gate EE-2003 Question Paper With Solutions

Q. 46 When stator and rotor windings of a 2-pole rotating electrical machine are
excited, each would produce a sinusoidal mmf distribution in the airgap with
peal valuesGate EE-2003 Question Paper With Solutions and Gate EE-2003 Question Paper With Solutionsrespectively. The rotor mmf lags stator mmf by a space
angleGate EE-2003 Question Paper With Solutions at any instant as shown in figure. Thus, half of stator and rotor surfaces
will form one pole with the other half forming the second pole. Further, the
direction of torque acting on the rotor can be clockwise or counter-clockwise. Gate EE-2003 Question Paper With Solutions

The following table gives four set of statement as regards poles and torque. Select
the correct set corresponding to the mmf axes as shown in figure.
