21225373.31 Slip Ring Induction Motor Lab is an important product designed to demonstrate the operating behavior & working
of Three Phase Machine. It provides complete learning contents to enhance practical knowledge and makes students
get to know the fundamental concepts of Three Phase Induction Machine.
The product includes comprehensive learning of various experiments such as running & reversing phenomenon, no
load test, block rotor test and load test of Three Phase Induction Machine. Students can measure the equivalent circuit
parameters along with losses, power factor under different loading conditions. Winding terminals brought out on top of
the motor with adequate protections so that the students can make connections by themselves.
