High Output Motor

Title

High Output Motor

Brief Introduction

YRKS series high output motor has advantages of compact structure, light weight, high efficiency, energy-saving, low noise and vibration, high reliability, long service life and convenient installation and maintenance, etc.

The motor manufacturer of shall supply a curve of base capability under site conditions over the specified range of primary or secondary coolant temperature (see Figure 3). For a generator with open-circuit air cooling, this coolant temperature can be taken to be the same as that of the air at the turbine intake (Figure 3, scale X). Where automatic re-circulation of air is fitted for low ambient temperature applications, the curve shall refer to the actual cooling air temperature differing from the ambient air at the turbine intake.

For indirectly cooled windings, the temperature rises when operating at site shall be in accordance with Tables 7, 8 and 9 of IEC 60034-1 as appropriate, adjusted as follows:

a) for primary coolant temperatures from 10 °C to 60 °C: add (40 – primary coolant temperature) K;

b) for primary coolant temperatures below 10 °C but not below –20 °C: add 30 K + 0,5 (10 – primary coolant temperature) K;

c) for primary coolant temperatures above 60 °C or below –20 °C, an agreement shall be reached;

For windings directly cooled by air or hydrogen the total temperatures when operating on site shall be in accordance with the limits of Table 12 of IEC 60034-1, adjusted as follows:

d) for primary coolant temperatures from 10 °C to 60 °C: no adjustment;

e) for primary coolant temperatures below 10 °C but not below –20 °C: subtract 0,3 (10 – primary coolant temperature) K;

f) for primary coolant temperatures above 60 °C or below –20 °C, an agreement shall be reached.
