Synchronous Induction Motor Circuit Diagram The idea of a rotating magnetic field was developed by françois arago in 1824. practical induction motors were independently invented by nikola tesla in 1883 and galileo ferraris in 1885. in 1888, tesla was granted u.s. patent 381,968 for his motor. three phase squirrel cage induction motors account for over 90% of the installed motor capacity. 8. wound rotor induction motor protection 371 9. rtd temperature detection 372 10. bearing failures 372 11. undervoltage protection 372 12. loss of load protection 373 13. anti backspin function 373 14. additional protection for synchronous motors 373 15. motor protection examples 374 network protection & automation guide a.c. motor protection.

Differential protection for lv & hv motors. differential protection is often provided for medium and large size motors with supply voltages of greater than about 4 kv, and electrically operated (shunt trip) circuit breakers. the differential protection provides high speed direction and clearance of faults on the motor stator windings.

A synchronous motor is a doubly excitation machine, i.e., its armature winding is connected to an ac source and its field winding is excited from a dc source. an induction motor is a singly excited machine, that is, its stator winding is energized from an ac source. speed. its speed is independent of the load. A synchronous motor is costlier than an induction motor of the same output and voltage rating. an induction motor is cheaper than the synchronous motor of the same output and voltage rating. an induction motor is also known as asynchronous motor. it is so called because it never runs at synchronous speed. i.e., ns = 120f p.
