The closest I can find (would like a power resistor) is 15 ohms which

give 2.35 A to the motor. (17% over)

Will this overheat the motor?


how close will this 82W heater be to the motor?

it realy depends on how hot the ambient temperature is.

have you considered PWM, or using a lower supply voltage?

Best guess is running short periods of time (30 seconds
max, but usually only a couple of seconds).


the motor is probably on even when stopped.
