demagnetization points are above 130 degrees Celsius, and some
even as high as 200 degrees Celsius, so the stepper motor surface
temperature of 80-90 degrees Celsius is normal.
How to determine the stepper motor driver DC power supply:
A. Determination of the voltageHybrid stepping motor driver
power supply voltage is generally a wide range (such as the IM483
supply voltage of 12 ~ 48VDC), the supply voltage is usually
based on the work of the motor speed and response to the request
to choose. If the motor operating speed higher or faster response
to the request, then the voltage value is high, but note that the
ripple voltage can not exceed the maximum input voltage of the
drive, or it may damage the drive.
B. Determination of Current
Power supply current is generally based on the output phase
current drive I to determine. If a linear power supply, power
supply current is generally preferable 1.1 to 1.3 times the I; if we
adopt the switching power supply, power supply current is
generally preferable to I, 1.5 to 2.0 times.
