Motor
A 4-pole motor of at least 23.8 kW drives this pump at 1450 rpm on 50 Hz. On a 60 Hz supply a motor with the same poles turns it at 1740 rpm, where it takes 28.6 kW. Order that motor wound for 60 Hz and rated for at least that power.
| Motor | kW | rpm | Frame | Class | A at 400 V | Suppliers |
|---|---|---|---|---|---|---|
| RN 200a4 | 30 | 1475 | IEC 200 | IE1 | 57 | |
| RN 180Lb4 uprated | 30 | 1465 | IEC 180L | IE1 | 58 |
The contactor and overload relay for each motor are on the motor's page.
