How to choose DINGS product?

STEP 1 - CHOOSING A MOTOR SIZE (FORCE REQUIREMENTS)

Here is a general overview of the Output Thrust vs. Motor Size:

35 300 230
42 600 230
57 1300 910

STEP 2 - CHOOSING A SCREW LEAD (FORCE AND SPEED REQUIREMENTS)

After estimating the required thrust and choosing a motor size that may fit your application, the speed and acceleration of the load must be considered and evaluated to choose and appropriate screw lead.

Due to the nature of lead screws, the output speed and output thrust achievable by a motor/lead screw combination are two proportional. increasing the required thrust will lower the achievable speed for a motor/lead screw combination. Therefore, the maximum output force of a system is lowered for applications that requires higher speed.

For complete motor/lead screw selection data, please refer to the Speed vs. Thrust curves for each motor size.

Although these two steps provide a solid foundation in motor/lead screw selection, other variables must also be considered:

  • Duty Cycle
  • Desired Life of a System
  • Environmental Considerations
  • Positional Repeatability
  • Acceptable Backlash
  • Acceleration / Deceleration
  • Driver
  • Vertical or Horizontal

Because of the numerous variables involved in motor selection. We highly remommended for users to proceed with physical testing to accurately determine the motor/lead screw combination required for a given application.

One of the most common methods of moving a load from point A to point B is through linear translation of a motor by a mechanical lead screw and nut.

This section is here to assist and refresh your understanding of the basic principles of lead screw technology. Some basic design consideration are as follows:

  • 1. What is the load of your system?
  • 2. What is the required linear speed?
  • 3. What is the distance to be travelled?
  • 4. What accuracy does your application require?
  • 5. What is the required time to move from point A to point B?
  • 6. What repeatability does your application require?
  • 7. Orientation is Horizontal or Vertical?

Although this section aims to provide a rough guideline to select a motor/lead screw combination that best fits an application, we recommend to contact our application engineering staff or sales representatives for further assistance with the motor selection process.
