Discussion Overview

The discussion revolves around selecting a linear stepping motor capable of applying a force of 10 Newtons to push a syringe. Participants explore how to interpret the motor's datasheet and the factors that influence its performance, including the design of the mechanism and the relationship between speed and force.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant inquires about how to read the datasheet to determine if the motor can apply the required force.
  • Another participant emphasizes the need for a mechanism to convert rotational motion to linear motion, suggesting that additional design considerations are necessary, including the length of motion and speed.
  • A later reply reiterates the importance of designing a mechanism for conversion but notes that the motor has a threaded rod, indicating it already provides linear motion.
  • One participant points out that the motor's ability to apply force depends on the speed of extension, highlighting that power output is a function of linear velocity and force, and references a graph in the datasheet that illustrates this relationship.

Areas of Agreement / Disagreement

Participants express different views on the requirements for selecting the motor, with some focusing on the need for a conversion mechanism and others pointing out the existing linear motion feature of the motor. The discussion remains unresolved regarding the specific interpretation of the datasheet and the implications for design.

Contextual Notes

Participants have not fully defined the assumptions regarding the speed and length of motion, which may affect the motor's performance. The relationship between power output, force, and speed is mentioned but not fully explored.

Hi,
There's more work to do before selecting the motor. You want linear force, but motors rotate, so you need to design a machine to do the conversion. You need to know the length of the linear motion and its speed, then design a mechanism and probably a gearbox.

Hi, if you take a look at the page the motor has a threaded rod going through it so its already a linear motion.

How do I read the data sheet here : http://www.haydonkerk.com/LinearAct...id/Size11LinearActuator/tabid/75/Default.aspx

To know if the motor is capable of applying such force?
It will depend on the speed at which you extend the actuator. Its power output is given by its linear velocity times the force it's developing, so you have a constraint there (since its power output is limited).

There's a graph of this relationship at the bottom of the page you linked.
