temperature of the stepper motor
April 24, 2012
I have created a small application with a stepper motor driven by a sparkfun big easy drive.
motor is here:
driver is this one:
control is made from arduino, source code taken from this example:
The motor is powered from a laptop charger which is rated at 12V-6Amps.
However, the motor is rated at 0.3 Amps.
The problem is that the temperature of the motor is very high. I have measured it after 10 minutes of run and it is above 95.5 Celsius. I suspect that is more because there is no fluctuation in the measurement ... so I suppose that is the maximal temperature that my probe can measure.
my question is why it is so hot ? Is this normal ?
I know that the source is rated at 6-Amps ... but the motor should take what it needs (0.3 Amps) not more ... right ?
Here is a picture with my device
