Which of inv-duty motors w/VFD is prefarable - increasing or reducing
vlad05 I missed that these are inverter duty motors rated for constant torque applications and therefore may be suitable for operating at the lower speeds without external cooling. Sorry.- coldbrew

Which of inv-duty motors w/VFD is prefarable - increasing or reducing
vlad05 On a variable speed drive application, the torque of the motor falls off roughly as a square at speeds above the 60hz rpm rating of the motor (constant hp range, torque is proportional to(v/hz)squared). Since this type of compressor is a constant torque application, you could experience...- coldbrew
