The rotor has salient poles, which are projections on the surface of the rotor that create a magnetic field. The stator has a winding that creates a magnetic field. When the stator winding is energized, the magnetic field from the stator interacts with the magnetic field from the rotor, and the rotor starts to turn.<\/p>\n<p>The air-gap between the rotor and stator is uniform in a reluctance-start motor. This is because the rotor is made of a solid piece of metal, and the stator is made of a laminated steel core. The laminated steel core has a uniform air-gap between the rotor and stator.<\/p>\n<p>The other options are all correct.<\/p>\n<p>A. It is similar to reluctance motor. A reluctance-start motor is a type of reluctance motor.<\/p>\n<p>B. It is basically an induction motor and not a synchronous one. A reluctance-start motor is an induction motor.<\/p>\n<p>C. So far as its basic working principle is concerned, it is similar to shaded pole motor. A reluctance-start motor is similar to a shaded pole motor in that it uses the reluctance of the rotor to start the motor. However, a reluctance-start motor is more efficient than a shaded pole motor.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;It is similar to reluctance motor&#8221; option2=&#8221;It is basically an induction motor and not a synchronous one&#8221;
