I believe George is correct: 90% is the efficiency at full rated load. At reduced load the efficiency will decrease to perhaps 85% at 20 horsepower; 75%...
... changing the voltage 90 volts will cause it to run 1/2 as fast, 198 volts will cause it to run 10% faster. If it has 4 leads, a somewhat wider range of...
