SUMMARY

Increasing the voltage on a homopolar motor, such as a Faraday disk, directly increases its speed by raising the potential difference, which in turn increases the current. This increase in current leads to a linear rise in torque, thereby enhancing the motor's performance. If voltage alone does not suffice for speed enhancement, alternative methods must be explored to optimize the motor's efficiency.

PREREQUISITES
  • Understanding of Ohm's Law and its application in electrical circuits.
  • Familiarity with the principles of electromagnetism as they relate to motor function.
  • Knowledge of torque and its relationship with current in electric motors.
  • Basic concepts of homopolar motors and their construction.
NEXT STEPS
  • Research the effects of increasing voltage on homopolar motor performance.
  • Explore advanced techniques for enhancing torque in electric motors.
  • Investigate alternative methods for increasing motor speed beyond voltage adjustments.
  • Learn about the design and optimization of Faraday disks for improved efficiency.
USEFUL FOR

Engineers, hobbyists, and students interested in electric motor design, particularly those focusing on homopolar motors and their optimization techniques.

Hi Guys, I need some advice and hopefully an explanation.

Does increasing the voltage on a simple homopolar motor increase its speed?
and
Why?

If voltage doesn't increase the speed, how can we increase the speed?

Thanks a lot, I've been searching for information but have not had a lot of success.

Martin

Im assuming you are talking about something like the faraday disk (too lazy to look up homopolar motor) but yes, raising the potential difference will linearly increase current (since its an ohmic metal you're using) which increases the torque (linearly)
