Motor Sizing Calculator
A motor sizing calculator is a tool that helps you find the motor of the right size for your specific needs. Whether you're working on a project that requires a motor for a machine, a vehicle, or any other application, our calculator makes it easy to determine how powerful the motor should be.
So, you just tell the calculator some details about your expectations from the motor, and it will suggest the accurate size of the motor in the form of the total power (Kilowatt) required. For this, you have to enter the motor's torque, the motor's required speed, and the motor's efficiency; the calculator will tell you the motor size that will work best. This is an ideal tool because it helps ensure that your motor is neither too weak to do the job nor too solid and costly for your needs. In short, it lets you pick the perfect motor for the job.
How to Calculate Motor Size?
If you want to determine the right size for your mechanical system or application, you shold know how to accurately use the motor sizing calculator. The motor sizing calculator from calculatorology is very simple to use. It has a very user-friendly interface. You need to follow th below steps to make the best use of it:
- Open the Calculator: Access your device's Motor Sizing Calculator tool.
- Enter Required Torque: Enter the torque needed for your application. The unit of torque is Newton meter (Nm).
- Enter Required Speed: Input the speed at which the motor needs to operate.THe unit of speed is revolution per minute (RPM).
- Enter Motor Efficiency: Enter the motor's efficiency percentage. This is usually a value between 0 and 100%, representing how effectively the motor converts electrical power into mechanical power.
Click the “Calculate” button to get the results. The calculator will use the information provided to determine the appropriate motor size for your needs.
Example;
Imagine you need to select a motor for a conveyor belt system in a factory. The system requires a motor that can provide a specific amount of torque and operate at a certain speed to handle the load efficiently. After assessing the requirements, you determine the following values:
- Required Torque: 50 Newton meters (Nm)
- Required Speed: 1500 revolutions per minute (RPM)
- Motor Efficiency: 85%
You input these values into the Motor Sizing Calculator to find the appropriate motor size.
Solution
Step 01: Calculate the Power Needed
P = Torque x Speed9.5488
- The factor “9.5488” converts the ubits to kilowatts (kW).
P = 50 x 15009.5488 785.4 W or 0.785 kW
Step 02: Adjust Efficiency
- Efficiency = 58 %
P = 0.78585 0.923 kW
Step 03: Results
To effectively meet the torque and speed requirements, you need a motor with a power rating of approximately 0.923 kW.
