Dynamometers
Magtrol offers three types of Dynamometers, each with a different braking system to absorb load: hysteresis, Eddy-current and powder. Magtrol’s dynamometers, electronics and software are used for testing all types of electric and pneumatic motors, gas engines and gearheads, as well as servo drives and inverters.
With over 50 dynamometers to choose from, and the availability of Customised Motor Test Systems (CMTS), virtually every motor testing requirement can be met.

View ProductRead moreHysteresis Dynamometers (HD Series)
Hysteresis Brake Dynamometers (HD Series) are versatile and ideal for testing in the low to medium power range (maximum 14 kW intermittent duty). With a Hysteresis Braking system, the Dynamometers do not require speed to create torque, and therefore can provide a full motor ramp from free-run to locked rotor. Brake cooling is provided by… Read more »

Magtrol’s WB 23 and WB 27 Eddy-Current Dynamometers are designed for very high-speed motors and dental or surgical tool testing applications. By providing a braking torque that is proportional to the rotational speed, rated torque is reached at the rated speed. The Dynamometer features a low level of inertia, due to small rotor dimensions, and… Read more »

Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by… Read more »

View ProductRead morePB Series Powder Brake Dynamometers
The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when… Read more »

Eddy-current Brake Dynamometers (WB series) provide increasing torque as the speed increases, reaching peak torque at rated speed. They are ideal for applications requiring high speeds and also when operating in the middle to high power range. Powder Brake Dynamometers (PB Series) provide full torque at zero speed and are ideal for applications operating in… Read more »

View ProductRead moreMSD Mega Speed Dynamometer
The MSD – Mega Speed Dynamometer was developed for testing very high speed motors such as BLDC, dental turbine and surgical tools. The braking affect is based on an Eddy Current induced aluminum disc directly mounted on the MUT (Motor Under Test) shaft. Torque is measured frictionless by a Reaction Torque Sensor mounted under the… Read more »

View ProductRead more4 Quadrant Dynamometer Test System
Magtrol’s 4 quadrant motorized dynamometers provides expanded testing flexibility over a typical braking dynamometer. With the ability to bring the motor under test (MUT) to synchronous RPM before beginning a test, repeatability is improved. Since the motor windings are at ambient temperature before starting a ramp test, wattage is more consistent. Custom Software is required… Read more »

Engine Dynamometers (ED Series)
With a Magtrol Engine Dynamometer, high performance motor testing is available to manufacturers and users of small gas engines. Magtrol’s Engine Dynamometers have been designed to address the severe, high vibration conditions inherent in internal combustion engine testing. Engine Dynamometers are part of Magtrol’s line of Hysteresis Dynamometers so they are highly accurate (± 0.25%… Read more »

View ProductRead moreDial Weight Dynamometers
The most important characteristic of any measurement instrument is repeatability and accuracy. The Magtrol Dial Weight Dynamometer uses the combination of a Hysteresis Brake and gravity to insure constant, reliable results. The brake torque rise is directly proportional to applied current. The calibrated weight system provides readings in standard engineering units through the use of… Read more »
