Discussion Overview

The discussion revolves around the feasibility of using multiple smaller torque motors connected to the same shaft to achieve a desired power output for a specific device design. The focus is on the theoretical and practical implications of daisy chaining torque motors, including considerations of motor specifications and drive capabilities.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant proposes the idea of using two or more smaller torque motors to match the power output of a single larger motor.
  • Another participant suggests that this approach is likely feasible and requests more information about the specific motors being considered.
  • A participant provides a link to a series of torque motors that may be suitable, indicating they are in the right size range.
  • There is a mention of the need for appropriate drive capabilities and programming to ensure the motors can work together effectively, highlighting potential complexities in implementation.
  • A later reply questions whether the daisy chaining concept is sound, indicating some uncertainty about the practical application of the idea.

Areas of Agreement / Disagreement

Participants generally agree on the conceptual soundness of the daisy chaining idea, but there are uncertainties regarding the specific implementation details and whether the proposed motors will meet the power requirements.

Contextual Notes

Limitations include the need for specific motor and drive compatibility, as well as potential nonobvious details that may affect the success of daisy chaining the motors.

Hi

I recently discovered torque motors and think they would be perfect for a device I’m designing, except for the fact that the power I need isn’t available in the size I’m looking for.

I’m wondering if two or more smaller torque motors connected to the same shaft can provide the same power as a single larger one?

Thanks

Probably, yes.
Can you post a link to the motors you are considering.
 
I haven’t found a perfect fit, but these are in the ballpark size-wise: technotion.com

QTR-A-160 SERIES​

 
These are industrial motors, not hobby motors, so the drives (servo amplifiers) should have that capability. Program the motion profile into one drive, then program the other drive for torque following. You may need to consult with the drive manufacturer because there are some nonobvious details that are necessary to make this work.

OK, thanks.

Those motors may not be exactly what I need, but the daisy chaining idea is conceptually sound?
