Our AC engine systems exceed others in wide range torque, power and rate performance. Because we style and build these systems ourselves, we have complete knowledge of what goes into them. Among other things, we maintain understanding of the materials being used, the fit between your rotor and shaft, the electric design, the natural frequency of the rotor, the bearing stiffness values, the component stress amounts and heat transfer data for differing of the motor. This allows us to push our designs to their limits. Combine all of this with this years of field experience relative to rotating machinery integration in fact it is easy to see how we can give you the ultimate advantage in your high performance 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 business lead the industry in lead moments for delivery; Please note that we possess the capability to provide custom designs to meet your specific power curve, speed performance and interface requirements. The tables here are performance features for standard electric motor configurations; higher power, higher rate, 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 result shaft is regulated exactly and easily through a control lever with a convenient fasten or a screw control to hold acceleration at a desired establishing. 
Adjustable speed drive models are available with result in clockwise or counter-clockwise rotation to meet up individual rate control requirements. Two adjustable rate drive models are equipped with a reversing lever that allows clockwise, neutral and counter-clockwise operation.
The general principle of operation of Zero-Max Adjustable Rate Drives gives infinitely adjustable speed by changing the length that four or even more one-way clutches rotate the output shaft if they move back and forth successively. The number of strokes per clutch each and every minute depends upon the input acceleration. Since one rotation of the input shaft causes each clutch to move backwards and forwards once, it is readily obvious that the input rate will determine the number of strokes or urgings the clutches supply the output shaft per minute.
