What is electrical shortening torque - in relation to what ?
electrical torque relates to strength of magnetic fields (amongst other things) generally concerning moving equipment or motors.
What is electrical shortening torque in terms of electrical generator?Yes; as oneye14 says, what was the context where you heard or read this term, or did it come from a World Wide Web translator?
But, without any context if an electric motor weighing 20 kgs or more dropped on one's head from a height of 5 or 6 meters it would likely result in some shortening, even if only temporary. Maybe. Probably. Possibly.
But, some context is necessary 'cause this is an unusual term all by itself.
