How the speed of synchronous motor changes with the
variation of load?
Answer Posted / iamdon
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.

Actuality I have at home electrical panel with 220v 50hz, and I want to converter from there to 110v 60hz, to wiring on the half of my house. Also I like to keep another half of my house with the original 220v 50hz. What is the best and safety way to do?
