engineering recuitment UKPSC Polytechnic Lecturer Mock Test 2024 Electrical Machines Alternator and Synchronous Motors
Why are large AC machines three-phase type synchronous machines?
1
These motors are self-starting.
2
Non-uniform torque is produced
3
Three-phase power is transmitted and distributed more economically than single phase power.
4
It gives the same output as single-phase machines.
