Title

6.6 KV Motor

Brief Introduction

YXKS series of high voltage 6.6 kv motor is a new generation product based on the company's long-term stable high-voltage three-phase asynchronous motor's experience of design and manufacturing, combined with the latest international standards. The efficiency values of motor averagely arrive at efficiency limit value of grade 2, which can largely promote the operation efficiency of customer.

Generators shall be capable of continuous rated output at the rated power factor over the ranges of ±5 % in voltage and ±2 % in frequency, as defined by the shaded area of Figure 1. The temperature rise limits in Tables 7 and 8, or the temperature limits in Table 12 of IEC 60034-1 shall apply at the rated voltage and frequency only.

NOTE 1:  As the operating point moves away from the rated values of voltage and frequency, the temperature rise or total temperatures may progressively increase. Continuous operation at rated output at certain parts of the boundary of the shaded area causes temperature rises to increase by up to 10 K approximately. Generators will also carry output at rated power factor within the ranges of ±5 % in voltage and −+3 5 % in frequency, as defined by the outer boundary of Figure 1, but temperature rises will be further increased. Therefore, to minimize the reduction of the generator's lifetime due to the effects of temperature or temperature differences, operation outside the shaded area should be limited in extent, duration and frequency of occurrence. The output should be reduced or other corrective measures taken as soon as practicable.
