VSM20A-48S 20mm diameter external drive long lead screw permanent magnet linear stepper motor
VSM20A-48S is 20mm diameter linear stepper motor with 135mm length extra long trapezoidal lead screw. The length of lead screw is adjustable.
Besides lead screw, motor’s resistance, step angle can all be customized.
Customers can adjust all the parameters based on their own requirement.
Screw lead determines motor’s linear speed and thrust, with longer lead, motor has higher linear speed, with smaller linear pushing force/thrust.
We have two different types of step angle, including 7.5° and 15°/step.
With higher rated voltage, motor has higher coil resistance, and it depends on customer’s power supplier and driver parameters.
Typical applications:
* Medical Equipment
* Linear Robotic Control
* Precision Calibration
* High Precision Valve
* Other Precise Position Movement
Plus tt has extra low noise and high stability.
