Answer / sindhu

force of attraction exists between two magnets......in such
a case when one of the magnet is moved in one direction,the
other magnet also moves in the same direction with the same
speed with which the first magnet was moved.the above
principle is called magnetic locking.this is the principle
of synchronous motor

Answer / radhakrishnan

Force between two unlike poles is known as magnetic locking

Answer / nilesh_sarate

In synchronous motor is known as induction motor in which
rotor received power in the form of induction just like
transformer pri. and sec. windings,
here in synchrouns motor stator winding is steady only
flux is rotating, while rotor is rotating, 90% of motors r
induction motors, rotor consist of cylindrical laminated
core with slots for carring conductors, but this are not
wires this are bars of coppers,aluminius,or alloys one bar
in each slots, this bars short circuited at end,this bars
are given slightly skew, to aviod locking tendancy of motor.
Now asuum the stator winding is parraler to which
three phase supply given and then rotating flux will
generat, now if u r rotor bars also will paraller then
there is possibility of locking., as both windings r
parralers.
