variable speed electric motor

Our AC electric motor systems exceed others in wide range torque, power and acceleration performance. Because we style and build these systems ourselves, we have complete knowledge of what goes into them. Among other activities, we maintain knowledge of the components being used, the match between your rotor and shaft, the electrical design, the organic frequency of the rotor, the bearing stiffness ideals, the component stress amounts and heat transfer data for differing of the engine. This allows us to push our designs to their limits. Combine all of this with this years of field encounter in accordance with rotating machinery integration and it is easy to see how we can give you the ultimate benefit in your powerful equipment.

We have a huge selection of standard styles of powerful motors to choose from in an array of cooling and lubrication configurations. And we lead the industry in lead moments for delivery; Please be aware that we possess the capability to provide custom styles to meet your specific power curve, speed performance and user interface requirements. The tables below are performance Variable Speed Electric Motor characteristics for standard engine configurations; higher power, higher swiftness, and higher torque levels can be achieved through custom design.

Externally, the Zero-Max Adjustable Speed Drive includes a rugged, sealed cast case, an input shaft, output shaft and speed control. Speed of the result shaft is regulated specifically and easily through a control lever with a convenient locking mechanism or a screw control to carry swiftness at a desired establishing. Adjustable speed drive versions are available with output in clockwise or counter-clockwise rotation to meet up individual acceleration control requirements. Two adjustable speed drive models are equipped with a reversing lever that allows clockwise, neutral and counter-clockwise operation.

The overall principle of operation of Zero-Max Adjustable Speed Drives gives infinitely adjustable speed by changing the length that four or more one-way clutches rotate the output shaft if they move backwards and forwards successively. The number of strokes per clutch per minute depends upon the input velocity. Since one rotation of the input shaft causes each clutch to go back and forth once, it is readily apparent that the input speed will determine the amount of strokes or urgings the clutches supply the output shaft per minute.
