SUMMARY

This discussion focuses on the feasibility of various torque constants for electric motors, specifically evaluating values ranging from 10 Nm/A to 10^11 Nm/A. It concludes that while lower torque constants are achievable, extremely high values such as 10^9 Nm/A and beyond are impractical due to physical limitations. Additionally, the maximum torque constant to resistance ratio is explored, with practical ratios being significantly lower than those proposed, emphasizing the need for realistic engineering constraints.

PREREQUISITES

Here are some "torque constants" for hypothetical electric motors. Tell me which ones are possible and which ones are not.

10 Nm / A

100 Nm / A

1000 Nm / A

10000 Nm / A

100000 Nm / A

1000000 Nm / A

10000000 Nm / A

100000000 Nm / A

1000000000 Nm / A

10000000000 Nm / A

100000000000 Nm / A

Also what is the maximum ratio of torque constant to resistance?

10 (Nm / A)/Ω

100 (Nm / A)/Ω

1000 (Nm / A)/Ω

10000 (Nm / A)/Ω

100000 (Nm / A)/Ω

1000000 (Nm / A)/Ω

10000000 (Nm / A)/Ω

100000000 (Nm / A)/Ω

1000000000 (Nm / A)/Ω

10000000000 (Nm / A)/Ω

100000000000 (Nm / A)/Ω

Does anyone have an answer?
 
Yo! so what's the answer?

This is not for school by the way.
