SM10 Linear Stepper Motor Run Through Shaft 10mm Diameter 9mm Stroke With Lead Screw

Mini 10mm diameter 9mm stroke run through shaft stepper motor with lead screw

This SM10 linear motor is 10mm diameter linear stepper motor.

The lead screw is M2.3 screw with 0.3mm pitch. (M2.3*P0.3)

The lead screw is specifically design for this product. (Non-standard lead screw)

The travel distance is about 9mm and you can not change its length, due to special design on the lead screw.

The lead screw length can’t be adjusted.

The thrust of this motor is over 200 grams, and its suitable for linear movement on small sized products, to carry a 200 grams load.

About linear stepper motor:

There different design:

Captive shaft(fixed shaft): the lead screw is not allowed to spin, it can only go up and down, do linear motor movement.

Run-throught shaft (through going shaft): the lead screw can move up and down when spinning. When lead screw is fixed, not allow to rotate, lead screw can move up an down, and work properly.

External drive(with nut): The lead screw is fixed, can’t move up and down, it can only spin, and there is a nut on the lead screw to move up and down.

About lead screw and step length:

We have two types of step angle: 15°and 7.5°. Motors with 15° step angle takes 24 steps for one turn, and motors with 7.5° step angle take 48 steps for a turn.

We have three types of lead screw lead, with single start/doule starts and 4 starts.

Pitch is the same: 0.6096mm

Lead screw lead=starts*pitch

For examples, for 2 starts lead screw, lead is 2*0.6096=1.2192mm

Motor’s step length, is the distance lead screw/nut travels when the motor takes one step.

Motor’s step length=lead screw lead/steps for each turn

For examples,for 2 starts lead screw, step angle is 7.5°,

Step length=lead/24=1.2192/24=0.0508mm/step

About thrust:

Thrust is related to driver’s frequency and lead screw lead, stepper angle and motor size.

The bigger motor’s size, thrust is bigger.

The lower frequency it get, motor rotate slower, and thrust is bigger.

The lower lead screw lead is, thrust is bigger.

7.5 degrees step angle will have higher thrust compared to 15 degrees.

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
