screw jack assembly lift screw jack motor

Usually , a jack system does not continue to be operated so frequently . So people do not care about a loss in electricity expenses by selecting a large motor , and tend to select a motor with a larger capacity than calculated value , considering that it would be better than an insufficient one .

The bigger the motor ,the better ?

No. Rather , in order to ensure the safety , be careful that the jack is not driven by unnecessarily large power .

Usually , a jack system does not continue to be operated so frequently . So people do not care about a loss in electricity expenses by selecting a large motor , and tend to select a motor with a larger capacity than calculated value , considering that it would be better than an insufficient one .

However , motors have the rotor inertia (J) , and this value increases along with an increase in the motor capacity .

Screw jacks are intended for performing a linear movement within a limited distance , so if the inertia is smaller , the overrun will be less .

Furthermore , if an obstacle gets stuck , the maximum torque of the motor will be imposed on the system , and it may damage the device . In contrast as the motor’s torque characteristics , it is deigned in a way that the start torque is 1.5 times larger than the rated torque , so it will sufficiently endure for a short time . Therefore , it is recommended to select a minimal motor .

Screw jack is used in applications where linear motion is required. Lifting of any load, pushing or pulling of mechanical equipment, adjusting of tight clearances of mechanical parts can be done by screw jacks. Mechanical capacity of screw jacks is between 5kN and 2000kN, Jack screws can be used as linear motors, linear actuators, or mechanical lifts depending on type of motion. Working Principle of Screw Jacks Main components of screw jacks are: trapezoidal lifting screw, worm screw, worm gear and gear housing, Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.

Electric screw jacks can also be called electric screw jacks, which include worm gear jacks and electric motors. The screw jack can be a self-locking trapezoidal screw jack or a high-precision ball screw jack. The motor can be a high-precision servo motor, stepping motor, helical gear motor, worm gear motor, three-phase asynchronous motor and 12v, 24v, 48v motors and DC gear motors, etc. If it is a high-precision ball screw jack, a brake motor or an external locking device is required to maintain the position.
