About this calculator
The Electric Motor Torque Calculator is designed to help you easily calculate the torque of an electric motor by inputting the motor speed and power rating. Torque, speed, and power are interrelated properties, and understanding this relationship is crucial when selecting the appropriate motor for any application. This tool allows users to quickly assess whether a motor’s torque is suitable for specific performance requirements.
This calculator is for:
- Mechanical engineers involved in designing systems with electric motors for various applications.
- Electrical engineers selecting motors for energy-efficient systems.
- Technicians performing performance checks or troubleshooting issues in motor-driven equipment.
The calculator provides quick feasibility checks for motor selection, ensuring that the torque output aligns with design needs or operational conditions. Alternatively, the manual approach to calculating torque involves using separate torque-speed-power relationships and converting units, which can be tedious and prone to human error. This tool simplifies the process, saving time and ensuring accuracy.
For a deeper understanding of motor torque and related calculations, "Electric Motors and Drives: Fundamentals, Types and Applications" by Austin Hughes is an excellent resource that explains the theory behind electric motor behavior and selection criteria.

FAQs
How are motor torque, speed, and power related?
Motor torque, speed, and power are directly proportional. If the speed of a motor increases while maintaining the same power, the torque decreases and vice versa. This relationship is fundamental to motor performance.
What factors affect the torque output of an electric motor?
The torque output of a motor depends on several factors, including the power rating, speed, voltage, and load conditions. These factors must be considered when selecting a motor for a particular application.
Why is torque an important consideration in motor selection?
Torque determines the motor’s ability to perform mechanical work. Motors with insufficient torque may struggle to start or maintain operation under load, making it critical to choose a motor with adequate torque for the application.

How to verify a calculation
Engineering calculations require clarity, precision, and professionalism. Here are some best practices we use at CalcTree:
- Technical Requirements: Start with boundary conditions, units, sign conventions, and design standards.
- Check the Math: Review the calculation step-by-step. Clarify unusual steps, compare results with hand calculations or tools, and test with multiple examples.
- Peer Review: Have an independent reviewer check for logic, accuracy, and compliance.
For more on verification, see CalcTree’s internal methods.
