Unusual markings on motor nameplate.
Unusual markings on motor nameplate.
(OP)
I have inherited a motor with a nameplate marked
Y/YY
460v
30/93A
I am not familiar with Y/YY on nameplate and also not sure why different amperage ratings with only one voltage rating any insight would be appreciated.
Thanks in advance for any replies. If it were up to me motor would be a boat anchor.

Assuming IEC markings.......
For high speed operation, supply 2W 2U 2V and short out 1U 1V 1W
For low speed operation, supply 1U 1V 1W and leave 2U 2V 2W open
