current is generally larger, and higher harmonic components,'embroidery
designs digitizing' (http://www.eagledigitizing.com/), the frequency of
alternating current with the speed of change, so the stepper motor
heating common situation,'embroidery digitizers'
(http://www.eagledigitizing.com/), and the case than the general AC
serious. 2, the reasonable range of stepper motor heat: heat to allow
the motor to what extent depends on the motor insulation. Internal
insulation properties at elevated temperatures (130 degrees) will be
destroyed. So long as no more than 130 degrees inside, the motor will
not damage, but when the surface temperature of 90 degrees below.
Therefore,'digitized embroidery designs'
(http://www.eagledigitizing.com/), the stepper motor surface temperature
of 70-80 degrees is normal. Useful for simple temperature measurement
point thermometer, you can also roughly determine: 1-2 seconds hand can
touch, not more than 60 degrees; hand can touch,'custom digitizing'
(http://www.eagledigitizing.com/), about 70-80 degrees; drop a few drops
of gas quickly of, then 90 degrees out. 3, the stepper motor speed
changes with heat conditions: constant current drive technology.
