MotorsQuestion 1220 of 1506

What are the characteristics of a line-driven synchronous reluctance motor?

Low power factor, weak pull-out torque, poor efficiency
High power factor, strong pull-out torque and high efficiency
Low power factor but very high efficiency under any load
Strong pull-out torque but low efficiency at full load

Show answer

Correct answer: Low power factor, weak pull-out torque, poor efficiency

The motor is cheap and gives moderate synchronous torque, but it is weak in these three areas.
