Motor Power Calculator
The Motor Power Calculator is a digital tool that allows you to match and find torque, speed and power values for your motor under test.
This will be particularly useful for motor testing, for sizing a new motor test bench, or for finding out whether your existing test bench is up to the required tests.
When performing a motor test, it is important to correctly size your dynamometer and associated torque transducer. These selections are directly proportional to your test specifications, and in particular to the speed, torque and power values of your motor. The dynamometer must be able to absorb the power of your motor. The torque sensor must have a measurement range that corresponds to the expected test, while offering sufficient mechanical resistance. Speed must be supported by all devices.
At Magtrol, we have a department specifically dedicated to building Customized Motor Test Systems (CMTS). Our experience and expertise in the field enable us to meet most requirements. Take a look at our portfolio of customized test benches and don’t hesitate to contact our sales team.

The International System of Units (SI)
The International System of Units, or SI, is a standardized system of measurement used worldwide. It is based on the international standard ISO/IEC 80000, which defines physical quantities and their units. It was designed to unify measurements and facilitate scientific, technological and commercial exchanges.
Adopted in 1960, the SI is based on seven base units, which serve as a universal reference:
- Metre (m): unit of length, defined on the basis of the speed of light in a vacuum.
- Kilogram (kg): unit of mass, based on Planck’s constant.
- Second (s): unit of time, defined by the vibrations of a caesium atom.
- Ampere (A): unit of electric current, linked to the elementary electric charge.
- Kelvin (K): unit of thermodynamic temperature, defined in terms of Boltzmann’s constant.
- Mole (mol): unit of quantity of matter, corresponding to the Avogadro number of elementary entities.
- Candela (cd): unit of luminous intensity, defined from a monochromatic light source.
These base units are used to derive other units, such as the Joule (J) for energy, or the Pascal (Pa) for pressure. The SI is universal and precise, making it an indispensable tool for science, industry and everyday life.
The Imperial System (US)
The American imperial system, also known as the United States Customary System (USCS), is a system of units of measurement still widely used in the USA, particularly in everyday life. Unlike the International System (SI), it is based on historical standards originating in the British Empire, before the latter officially adopted the metric system.
This system is based on several main units:
- Length: The basic measurement is the foot (ft), equivalent to approximately 30.48 cm. Other units include the inch (inch), the yard (yd) (3 feet) and the mile (5,280 feet, or approx. 1.609 km).
- Mass/weight: The main unit is the pound (lb), equivalent to about 0.454 kg. The ounce (oz) is also used for lighter weights (1 lb = 16 oz).
- Volume: Liquids are measured in gallons (gal), where 1 gallon is equivalent to approximately 3.785 liters. Sub-units such as quart (qt), pint (pt) and fluid ounce (fl oz) are also used.
- Temperature: Temperature is expressed in degrees Fahrenheit (°F), where 32°F is the freezing point of water, and 212°F is its boiling point (under normal pressure).
The imperial system is often criticized for its lack of uniformity and complexity, as conversions between units are not based on a decimal system (like SI). For example, it takes 12 inches to make a foot, but 16 ounces to make a pound.
Although the metric system (SI) is officially used in most countries, the imperial system remains deeply rooted in American culture and practices, particularly in the fields of construction, cooking and road distances.
