The stepper motor calculator serves as a valuable tool for engineers, hobbyists, and enthusiasts alike, offering a streamlined approach to determining key performance parameters of stepper motors.

By inputting specific motor specifications like current, Inductance, voltage, and steps/revolution, users can obtain essential insights into the motor’s capabilities, including its maximum speed, minimum time per step, and maximum power dissipation.

Here are the formulas for the Stepper Motor Calculations:

Where:

V = applied voltage

Imax = maximum current

L = stepper motor inductance

spr = steps per revolution

A stepper motor is a type of brushless DC electric motor that divides a full rotation into a series of equally sized steps. Unlike traditional DC motors, which continuously rotate when supplied with power, stepper motors move in discrete increments, or steps, making them ideal for applications requiring precise positioning and control.

This characteristic is achieved through the interaction of electromagnets and a toothed rotor, allowing the motor to accurately stop and hold its position without the need for feedback mechanisms.
