Electric Screw Jack Detailed Informations:

For easy installation, Every type worm gear screw jack can be directly connected with electric motors by motor flange. Motor mounts allow direct coupling of the motor shaft with either the right or left side jack input shaft. All mounts come with necessary hardware and coupling keys. All standard electric motors are 3 phase, 380VAC, 50 Hz, 1440 rpm. Special motor electricity systems like 110~460VAC, 50/60Hz, Single/Three Phases or 24VDC, we can make them follow clients' order.

About motor drive power, please check the worm gear screw jack specification table. Operating horsepower does not less than the datas on the specification table. The lifting speed depends on the use of screw jack, the control of motor speed is necessary. Electric motor drive revolutions are not exceed 1800 RPM.

Electric Screw Jack Lifting Speed Formulas:
V=R1*P/R2
V=R1*T
V :lifting speed
R1:input RPM
P :screw pitch
R2:gear ratio
T :travel stroke per revolution
Example, 4 poles(1500 rpm) electric motor,jacks model RN-0.5T-1/5(1 turn 1 mm travel),screw pitch 5 mm.
V=1500*5/5=1500 mm/min
V=1500*1 mm travels per turn=1500 mm/min
