| MULTI-SPEED MOTORS • APPLICATION DATA | ||
| Variable torque motors have horsepower ratings that vary as the square of the speed, while torque varies directly with the speed. These motors are typically used on applications such as fans, blowers and centrifugal pumps. | Constant torque motors are capable of developing the same torque for all speeds. Their horsepower ratings vary directly with the speed. Constant torque motors are used on mixers, compressors, printing presses, extractors, feeders and laundry machinery. | Constant horsepower motors develop the same horsepower at all operating speeds, and the torque varies inversely with the speed. These motors are often used on machine tools, such as drills, lathes, punch presses and milling machines. Please contact iProcesSmart.com with details for constant HP applications. |
