8mm linear stepper motor actuator screw slider 2 phase stepper
motor for precision medical devices
VSM0825 is a precision micro 8mm diameter stepper motor with a
screw pitch of 0.4mm on the output shaft, which is supported by the
screw and rotates into thrust.
The basic step angle of the motor is 18 degrees, and the motor runs
20 steps per week, so the displacement resolution can reach 0.02mm,
achieving precise control.
The actuator adopts a subdivision driving method to meet the
requirements.
The output part of the motor includes connecting wires, FPC, and
bare needles, which can be customized according to customer
installation requirements
Mechanical Dimension:MM
Technical Features
Because of its small size, high precision, easy to control and
other excellent characteristics, so this micro stepper motor is
widely used in the camera, optical instruments, lenses, precision
medical devices, automatic door locks and other fields.
The motor input part of the FPC, but can according to the customer
demand can be changed to a connecting line needle, PCB and other
forms.
The mounting bracket can be changed according to the customer's
request.
