I want some data on some old WRIM-motors we use in our plant, to check their settings. The manufacturer doesn't exist anymore, so I don't know where to obtain the data. Can I assume any values or is there any average value I can use for:
1. Safe hot stall time?
2. Permissible start attemps / hour?
The nameplate values of the motors is:
Power: 500kW; 450kW; 220kW; 200kW
rpm: 1483rpm; 495rpm; 1479rpm; 1497rpm
Stator V 3300V
Stator I 115A; 110V; 51.9A; 49A
Rotor V 855V; 613V; 399V; 390V
Rotor I 347A; 434A; 323A; 305A
Frequency 50Hz
Any help will be appreciated
Thanks
