What is the formula for the length of each damper bar for small machines?
(a) length of each damper bar = 1.1 * axial length
(b) length of each damper bar = axial length + 0.1
(c) length of each damper bar = axial length – 0.1
(d) length of each damper bar = 1.1 / axial length
I got this question during an interview.
My doubt stems from Design of Rotor in chapter Design of Synchronous Machines of Design of Electrical Machines
