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
