The voltage of the step motor driver?
Step 1 determine the voltage of the motor drive Hybrid stepping motor drive power supply voltage is usually a wide range, such as power supply voltage IM483 for 12 ~ 48 VDC), the power supply voltage is usually according to the requirements of the machine work speed and response to choose. If the motor rotation speed higher demand or response quickly, so the voltage value is high, but pay attention to the power supply voltage ripple cannot exceed the maximum input voltage of the drive, otherwise may damage the driver. Step 2 determine the current of the motor drive The power supply current is determined by the output phase I of the actuator. If a linear power supply is adopted, the current of the power supply should be 1.1 to 1.3 times as desirable. If switch power supply is adopted, the current of the power supply is 1.5 ~ 2.0 times that of I. In the motor drive: according to the electric current of the motor, the actuator is greater than or equal to this current. If low vibration or high precision is required, the breakdown driver can be allocated. For high torque motor, use high voltage drive as possible to obtain good high speed performance
The output performance of the high voltage will improve the output performance of the motor. General motors have a certain amount of waste to choose from, it is recommended to use low point smoke, if the speed is high, can increase voltage and current properly!
Input voltage affects the torque of stepping motor, the motor speed is proportional to the pulse frequency and startup if frequency is too high, stepping motor will not be able to spin, because the stator magnetic field changes too fast, the rotor can't keep up with, have to make the rotor has a acceleration process. Stop too, to have a slow process, do not suddenly stop pulse.
