Propeller is power of executing agency, was made of motor and ball screw , it can convert rotation into linear motion. Pay attention to thrust, velocity, effective travel and swing direction when selection.

A . standard motor ball screw propeller：

       Characteristic: use AC constant magnetism low-speed synchronous motor, so thrust is smaller. Range from 500N, 1000N, 2000N to 3000N. Has two working speed,5mm/s and 10mm/s; effective travel has ±25mm,±50mm,±75mm etc. swing direction has vertical and horizontal, swing angle is ±8⁰.You can choose from when select.

B . Big thrust frequency conversion motor ball screw propeller:
 

        Characteristic: use AC asynchronous speed-low machine, different thrust from 1ton , 2ton to 5ton. has tow speed, low-speed is 10mm/s and high-speed is 20mm/s, driver by frequency conversion motor; effective travel has±100mm, ±150mm. In general, use for large feed-up machine and take-up machine.
