Stepper Motor Power Supply Calculator

The current driver chip is limited to supply 0 7a.

Stepper motor power supply calculator.

Stepper motor maximum speed and power calculator. The average current consumed by the stepper motors is what is most important for sizing the power supply. Stepper motors are normally used for positioning and are not known for their speed. This calculator computes the maximum speed of a stepper motor which is limited by the time it takes for the coil to energize to it s maximum holding current and then de energize as polarity flips.

We are using a 12v power supply. We are using a stepper motor with a current rating of 0 65a and rated voltage of 4 55v. If your motor power supply voltage is from 7 5 to 15 volts then you may choose to use a single supply to operate the system. The peak current listed in the datasheet is only achieved for a brief period during the motor coil charge cycle.

Note that the current capabilities of the supply must exceed the sum of the current requirements of the motor s and the logic circuits. Power supply circuits. This tool is designed to calculate the maximum speed of a stepper motor as well as the minimum time per step and the maximum power dissipation. With this stepper motor calculator you can quickly calculate the speed of the stepper motor in your circuit.

To use this calculator simply supply the required fields and click the calculate button. Or will it be equal to motor rated voltage rated current.
