What is the power factor in the reluctance motor and the range of efficiency?
(a) leading power factor, 60-75%
(b) lagging power factor, 50-75%
(c) zero power factor, 55-80%
(d) lagging power factor, 55-75%
The question was asked during a job interview.
This is a very interesting question from Design of a Small Reluctance Motor topic in chapter Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines
