variable speed electric motor

Our AC motor systems exceed others in broad range torque, power and velocity performance. Because we Variable Speed Electric Motor design and build these systems ourselves, we’ve complete knowledge of what switches into them. Among other things, we maintain knowledge of the materials being used, the match between the rotor and shaft, the electrical design, the natural frequency of the rotor, the bearing stiffness ideals, the component stress levels and the heat transfer data for various parts of the electric motor. This allows us to force our designs to their limits. Combine all of this with this years of field experience relative to rotating machinery integration and it is easy to observe how we can give you the ultimate advantage in your high performance equipment.

We have a large selection of standard designs 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 unique power curve, speed overall performance and user interface requirements. The tables here are performance characteristics for standard engine configurations; higher power, higher acceleration, and higher torque amounts may be accomplished through custom design.

Externally, the Zero-Max Adjustable Speed Drive contains a rugged, sealed cast case, an input shaft, output shaft and speed control. Swiftness of the output shaft is regulated exactly and quickly through a control lever which includes a convenient fasten or a screw control to hold swiftness at a desired setting. Adjustable speed drive models are available with output in clockwise or counter-clockwise rotation to meet up individual quickness control requirements. Two adjustable velocity 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 amount of strokes per clutch each and every minute is determined by the input velocity. Since one rotation of the input shaft causes each clutch to go back and forth once, it is readily obvious that the input acceleration will determine the amount of strokes or urgings the clutches give the output shaft each and every minute.
