Our AC electric motor systems exceed others in wide range torque, power and rate performance. Because we design and build these systems ourselves, we have complete knowledge of what goes into them. Among other activities, we maintain understanding of the components being used, the fit between the rotor and shaft, the electrical design, the organic frequency of the rotor, the bearing stiffness ideals, the component stress levels and the heat transfer data for various parts of the motor. This enables us to press our designs with their 
limits. Combine all of this with our years of field experience relative to rotating machinery integration and it is easy to observe how we can provide you with the ultimate benefit in your high performance equipment.
We have a huge selection of standard styles of powerful motors to select from in an selection of cooling and lubrication configurations. And we lead the industry in lead times for delivery; Please note that we possess the capability to provide custom styles to meet your specific power curve, speed performance and interface requirements. The tables here are performance features for standard motor configurations; higher power, higher velocity, and higher torque amounts can be achieved through custom design.
Externally, the Zero-Max variable speed gear motor china Adjustable Speed Drive contains a rugged, sealed cast case, an input shaft, output shaft and speed control. Rate of the result shaft is regulated specifically and very easily through a control lever with a convenient locking mechanism or a screw control to carry velocity at a desired environment. Adjustable speed drive models are available with output in clockwise or counter-clockwise rotation to meet individual rate control requirements. Two adjustable velocity drive models include a reversing lever that permits clockwise, neutral and counter-clockwise operation.
The overall principle of operation of Zero-Max Adjustable Swiftness 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 each and every minute depends upon the input velocity. Since one rotation of the input shaft causes each clutch to go back and forth once, it really is readily obvious that the input speed will determine the amount of strokes or urgings the clutches supply the output shaft per minute.
