Speed of synchronous motor WILL NOT CHANGE with the
variation of load, subjected to the LOAD VARIATION WITHIN
the rarted load capacity.

Synchronous mator is a CONSTANT SPEED MOTOR which EITHER
runs at synchronous speed(hence the name) OR not run at all.
If load exceed the rating it will stall(not run).

Synchronous speed is independent of load variation.It is
given by following relation
(120*frequency of AC supplied to armature)/No of pole on
rotor.
