15mm trapezoidal screw 18 degrees PM linear stepper motor with
hexagonal nut
Description:
This is a 15mm diameter stepper motor attached with a lead screw
and nut.
The lead screw is trapezoidal screw, and lead screw’s part No. Is:
Tr3*1P*2N
Tr3 means it’s a trapezoidal screw and screw’s outer diameter is
3mm
1P means the pitch is 1mm
2N means the lead screw has 2 starts
Thus the lead of this screw is 2N*1P=2mm
The nut on lead screw is a hexagonal nut.

About linear stepper motor with slider:
Our slider motor is a full set of assembly including motor + lead
screw + bracket + slider.
Motor’s step angle is generally 18°/step, which means 20 steps for
each turn.
When motor rotates one turn, slider moves one lead.
For single start lead screws: pitch =lead.
So the step length is (step length means linear movement slider
travels, when the stepper motor take exactly one step):
Lead screw lead/steps of each rotation
For example if lead screw is M2*0.4P (0.4mm pitch regular M2 lead
screw), step angle of the motor is 18°, step length of this motor
is 0.4mm/20=0.02mm/step.
Also, lead screw length is customizable, and we also need to adjust
bracket’s design, if you customize lead screw length.
Application of stepper motors:
Stepper motors are used for precise control, widely used on medical
equipment, 3D printer, industrial precise control, automation
equipment, etc.
Stepper motors can be used in any mechanisms requirement precise
conrtol and rotational/linear movement.
Advantage of stepper motors:
Stepper motor can reach precise control even without close-loop
encoders / without feed back system, also they do not have
electrical brushed. Thus there is no electromagnetic interference
and electrical sparks issues. In some cases, they can replace DC
brushed motors/ brushless motors.
Stepper motors are easy to control with drivers, and this feature
establish its important position in the field of precise control.
1. Precise control achievable, programmable
2. Without electromagnetic interference & electrical sparks
3. Small size
4. Reasonable price
5. Low noise
6. Long service life
