Stall Torque Calculator

In automotive engineering, stall torque is a critical parameter. Our stall torque calculator pairs well with the wheel torque calculator, offering insights into vehicle torque characteristics.

How to Use the Stall Torque Calculator

The Stall Torque Calculator is designed to calculate the stall torque of a motor or engine. The stall torque represents the maximum torque output that the motor or engine can generate when operating at stall (zero speed). By inputting the power, speed, and torque coefficient, users can obtain an estimate of the stall torque. This information is valuable for motor selection, system design, and torque-related calculations.

Primary Applications of the Calculator

The primary applications of the Stall Torque Calculator are as follows:

• Motor Selection: The calculator assists in motor selection for various applications. By calculating the stall torque, users can determine whether a motor can generate enough torque to meet the requirements of a specific task or application. This is crucial for ensuring motor performance and preventing motor stalling.
• Engineering and Design: Engineers and designers can use the calculator to assess the torque characteristics of motors or engines within their systems. The stall torque helps in designing appropriate gear systems, power transmission components, and torque conversion mechanisms. It enables engineers to optimize system performance and ensure torque requirements are met.
• Mechanical Maintenance and Troubleshooting: The calculator is a valuable tool for mechanics and technicians involved in motor maintenance and troubleshooting. By calculating the stall torque, they can assess motor health, identify performance issues, and diagnose problems related to torque generation. This aids in efficient maintenance and repairs.

Instructions for Utilizing the Stall Torque Calculator

To utilize the Stall Torque Calculator effectively, follow these steps:

• Power: Input the power value in watts (W) in the designated input field. Power represents the rate at which work is done or energy is transferred. Consult motor specifications or power rating information to obtain the correct power value.
• Speed: Enter the speed value in revolutions per minute (RPM). Speed represents the rotational velocity of the motor or engine. It is essential to input the correct speed to obtain accurate results. Refer to motor specifications or measure the rotational speed using appropriate instruments.
• Torque Coefficient: Input the torque coefficient value. The torque coefficient relates to the motor or engine's torque characteristics and efficiency. It may be provided in motor specifications or obtained through motor testing and analysis.

After providing the required inputs, click the Calculate button to obtain the results.

Output Fields and Interpretations

The Stall Torque Calculator provides the following output fields:

• Power: This field displays the power value you entered. It helps you verify that the calculator has considered the correct power in the calculations.
• Speed: The speed field shows the speed value you input. It confirms that the calculator has taken the correct speed into account.
• Torque Coefficient: This field presents the torque coefficient value you entered. It ensures that the calculator has considered the correct torque coefficient for the calculations.
• Calculated Result: This field displays the estimated stall torque of the motor or engine based on the provided inputs. The stall torque represents the maximum torque output at stall condition. It is displayed in Newton-meters (Nm).

Stall Torque Formula

The Stall Torque Calculator employs the following formula to calculate the stall torque:

Stall Torque = (9.5488 * Power) / (Speed * Torque Coefficient)

In this formula, the power, speed, and torque coefficient are considered to determine the stall torque. The calculated result is obtained by multiplying the power by a conversion factor and dividing it by the product of the speed and torque coefficient. The formula represents the relationship between these variables and provides insights into the maximum torque output.

Illustrative Example

Let's consider an example to illustrate how the Stall Torque Calculator works:

Suppose a motor has a power rating of 500 Watts, operates at a speed of 2000 RPM, and has a torque coefficient of 0.85.

To calculate the stall torque, we can use the calculator:

• Power: 500 Watts
• Speed: 2000 RPM
• Torque Coefficient: 0.85

After inputting the values and clicking Calculate, the calculator determines that the estimated stall torque is approximately 22.31 Nm.
