A cylindrical rotor alternator can also run as reluctance motor.

A. True

B. False

This question was posed to me at a job interview.

This is a very interesting question from Power Angle Characteristics of Synchronous Machines topic in division Synchronous Machines of Electrical Machines

Right option is B. False

For explanation: The net reluctance power for a cylindrical rotor type alternator will be zero if the field excitation is made zero. There will not be any torque generated.
