Stepper Motor Torque Calculator

Introduction

Stepper motors play a crucial role in various applications, from robotics to CNC machines, offering precise control over angular displacement. One key parameter that engineers often need to calculate is the motor torque. The Stepper Motor Torque Calculator simplifies this process, providing a quick and efficient way to determine the torque based on the motor torque constant and total current.

Formula

The formula used by the Stepper Motor Torque Calculator is derived from the basic relationship between torque ( $T_{s m}$ ), motor torque constant ( $K_{T}$ ), and total current ( $i$ ):

T s m = K T * i

Here, $T_{s m}$ is the stepper motor torque in Newton-meters (N-m), $K_{T}$ is the motor torque constant in N-m/amp, and $i$ is the total current in amperes. This simple yet powerful formula allows engineers to quickly estimate the torque generated by a stepper motor.

How to Use the Stepper Motor Torque Calculator

Using the calculator involves a few straightforward steps:

Enter Motor Torque Constant: Input the motor torque constant ( $K_{T}$ ) into the designated field.
Enter Total Current: Input the total current ( $i$ ) into the designated field.
Click Calculate: Press the “Calculate Torque” button to perform the calculation.
View Result: The calculated torque will be displayed, providing valuable insights into the stepper motor’s performance.

Example

Let’s consider an example where the motor torque constant ( $K_{T}$ ) is 0.1 N-m/amp, and the total current ( $i$ ) is 3 amps. Using the formula:

$T_{s m} = 0.1 N-m/amp \times 3 amps$

The calculated torque ( $T_{s m}$ ) would be 0.3 N-m. This means that, in this scenario, the stepper motor would generate a torque of 0.3 Newton-meters.
