Stepper Motor

Stepper motors divide a full rotation of the rotor into a number of equally sized "steps," offering the ability to quickly position a load and hold it at any one of these steps. Also known as step motors or stepping motors, these brushless DC motors offer quick, precise positioning and exceptional holding torque. Stepping technology allows for the use of an open-loop controller – simplifying machine design and lowering total cost compared to a servo motor system. High-performance, brushless, maintenance-free stepper motors provide precise, extremely cost-effective motion control.
JACTON ball screw jack, machine screw jack, acme screw jack, worm screw jack, cubic screw jack with Stepper motors for for greater control of acceleration, de-acceleration, travel rate and positioning accuracy than IEC or NEMA framed motors, called Stepper-Motor-Jack.
When motor driven double screw jack lift system or multiple units screw jack lift system, or the load objects sizes are too large, or very high precision are required, but no space for connecting shafts, couplings, miter gearboxes, pillow blocks with one motor controls for synchronous linear motions. Under this conditions, require separate double Stepper-Motor-Jack or multiple units Stepper-Motor-Jacks.
