Shunt motors

WebAns: In Brush Less DC Motors, the armeture (coil winding to form poles) is put on stator and rotor is made using Permanent Magnets. When the armeture of the stator is passed through DC current , the Magnetic field is generated. However when fixed DC current is applied this will generate a constant magnetic field and rotor can not run with this. WebThis preview shows page 50 - 53 out of 119 pages. 38.
