would the life of the motor be shortened?
DickDV said:If the motor is 100hp or smaller, you can run it at half speed fully loaded without concern for overheating--this according to most manufacturer's published data for ODP and TEFC motors.
In fact, under 10hp, you can go as low as one-quarter base speed without concern.
This isn't my data now, it's the manufacturers!
