SUMMARY

Daisy chaining torque motors can effectively increase power output for applications requiring more torque than a single motor can provide. The discussion highlights the use of the QTR-A-160 SERIES torque motors from Tecnotion, which are industrial-grade and suitable for this purpose. Proper configuration of servo amplifiers is essential, including programming one drive for the motion profile and the other for torque following. Consulting with the drive manufacturer is crucial to address specific implementation details.

PREREQUISITES
  • Understanding of torque motors and their specifications
  • Familiarity with servo amplifiers and their programming
  • Knowledge of motion control systems
  • Basic principles of daisy chaining electrical components
NEXT STEPS
  • Research the QTR-A-160 SERIES torque motors from Tecnotion
  • Learn about programming servo amplifiers for motion profiles
  • Explore the concept of torque following in motor control
  • Consult technical documentation from drive manufacturers for implementation guidelines
USEFUL FOR

Engineers, designers, and developers working on motion control systems, particularly those looking to optimize power output in compact designs using torque 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?
