Need help with gearing and electric motor related things

Need help with gearing and electric motor related things

I am not a mechanical engineer or understand any of it at all and all the info I found online was Google search.

I am trying to match to the same motor spec which is 150,000 HP.
The torque I got online was 437666.6667 for the 150,000 HP.
If I was to use a gear ratio of 30:1, the estimate torque I need on the motor would be 14589 @ 60RPM, which is 167 HP.
I think my calculation might be wrong, would it be possible if you correct me?

1 = From Electric motor
30 = To Generator

Electric motor RPM is 60RPM with 14589 foot pound of torque @187HP
Output estimate is 1800 RPM with 437666.6667 foot pound of torque @150,000HP

Electric motor>>>>>A side of gear>>>>>>>> output to be side of gear where its 30x the more than A side of gear

RE: Need help with gearing and electric motor related things

While I appreciate your honesty in admitting that you are not a mechanical engineer, your post does exhibit a woeful lack of understanding of even basic science.

How do you expect to get an output power of 150,000hp from an input power of 187hp with just your gear drive? Your speed increasing gear drive will not create power, it will only change the shaft speed. And the change in shaft torque will simply be a function of the gear ratio minus any mechanical losses produced in the drive train.

RE: Need help with gearing and electric motor related things

Wouldn't change in torque also affect Horsepower too?
Since Torque and RPM are related to Horsepower.

RE: Need help with gearing and electric motor related things

You've got your output increasing in both speed and torque. That's wrong. Your torque will go up by the gear ratio (ignoring losses) but your speed will go down by the gear ratio.
