Answered: Motor Power

In a situation where a motor is being used to lift an arm instead of a servo I have been advocating gearing the motor for torqe even if its not absolutly necessary. I say this for two reasons: One, the value that is given to the motors is a power not a speed, so a motor that is comfortably able to handle a certain load at a power of 100 will fail to move at a power of 50. So gearing the motor for torque allows the speed to remain pretty much the same, by running the motor at a higher power, and gives you more torque with the same precision. Two, the speed at which the arm has to move in these kinds of situations is probably much slower than a motor running at full speed, so the strategy will not be affected. Am I correct in all my assumptions and in advocating this strategy? Thank you.

**Yes you can change the finial output of a motor with gearing. Gearing will change the speed and the torque of the finial output – more rpm will be at less torque while less rpm will be at a greater torque. **
