# Horse Power

Does anyone know how much HP is created by a CIM?

Currently we have 2 running in a custom transmission with a 7.1:1 reduction.

340 watts = 0.45594751 hp
(confirm watts?)

Certainly no more than 480 watts, since the CIMs can theoretically consume 40 Amps (before the breakers trip) over 12 volts, which equates to 480 watts (Power = Current * Voltage). However, due to losses from heat (which is quite substantial, just try to put your hand on a CIM after a match) this number is probably much lower.

What Shooter said, although I believe the max power is 343 watts at 66 amps. After gearbox losses, It’s likely to be closer to 280-310 watts per motor, or .375-.415 HP per motor.

Thanks. One more, how do I find out how much torque is applied after the gear box?

You’ll have to be more specific, as the torque output by the motor will be dependent upon the current being applied to the motor, which is then dependent upon the voltage and spinning speed, which itself is based upon what resistance it encounters and the torques being applied.
