R

Regulation %

$V subscript r e g end subscript percent sign equals fraction numerator left parenthesis V subscript N L end subscript minus V subscript F L end subscript right parenthesis over denominator V subscript N L end subscript end fraction cross times 100$

Rotor frequency

$f subscript r equals fraction numerator S l i p percent sign cross times f subscript s u p p l y end subscript over denominator 100 end fraction$

The rotor frequency is equal to the supply frequency times the slip percentage divided by 100
