Tips on replacing an old Brook Slip ring
(OP)
Hi Guys,
Can you give ma any tips on replacing an old Brook Slip ring 60Hp 6 pole 63 amp Rotor current, 78 amp Stator current, Ac Motor. This motor is on a small crusher originally used for crushing stone but now used as part of a re-cycling process where it crushes 4" concrete blocks. The new load is not as demanding as the machine was intended for, but I want to stay with a similar rated new Ac standard Motor. I was thinking of using a 55Kw 6pl 400V std motor with a 160Kw Soft start. Can you give me a guide as to the best way to replace this old motor.
Thank You.

Under "Glossary of Motor Terms" look at Design
Do not confuse the Design letter with the code letter.
You may consider a design "D" or design "C", depending on your load.
For rocks you would probably want a design "D". For concrete blocks you may be able to use a design "C".
