## About Electric Motor Torque Calculator (Formula)

The Electric Motor Torque Calculator is a tool that helps determine the torque produced by an electric motor based on various input parameters. Torque is a crucial parameter in assessing the rotational force or twisting power generated by a motor, which is essential for many applications, including machinery, robotics, and automotive systems.

The formula used to calculate the electric motor torque is as follows:

t = (I * V * E / 100 * 60) / (rpm * 2 * π)

Where:

• t represents the torque in Newton-meters (Nm)
• I denotes the current in amperes (A)
• V represents the voltage in volts (V)
• E denotes the efficiency of the motor as a percentage (%)
• rpm refers to the motor’s rotational speed in rotations per minute
• π is the mathematical constant pi (~3.14159)

To use the Electric Motor Torque Calculator, you need to input the values for current, voltage, efficiency, and RPM into the respective fields. Once you click the “Calculate” button, the calculator applies the formula and provides the torque output.

Efficiency plays a significant role in motor performance, as it represents the ratio of useful output power to the total input power. A higher efficiency value indicates a more efficient motor, resulting in better torque output.

By utilizing the Electric Motor Torque Calculator, engineers, hobbyists, and professionals can quickly assess the torque produced by an electric motor based on the provided input values. This information is valuable for motor selection, system design, and ensuring the motor meets the required torque specifications for a given application.

It’s important to note that the formula assumes torque is measured in Newton-meters (Nm). Adjustments may be necessary based on the specific unit requirements or conversions.

The Electric Motor Torque Calculator simplifies the process of evaluating motor torque, aiding in the design and optimization of various systems that rely on electric motors.
