A. Determination of voltage: The power supply voltage of the hybrid stepping motor driver is generally a wide range (for example, the power supply voltage of the IM483 is 12 to 48 VDC), and the power supply voltage is usually selected according to the operating speed and response requirements of the motor. If the motor has a higher operating speed or a faster response, the voltage is also higher, but note that the ripple of the supply voltage cannot exceed the maximum input voltage of the drive, otherwise the drive may be damaged.
B. Determination of current: The supply current is generally determined by the output phase current I of the driver. If a linear power supply is used, the supply current can generally be 1.1 to 1.3 times that of I; if a switching power supply is used, the supply current can generally be 1.5 to 2.0 times that of I.
