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 the low to middle speed range or when operating in the middle to high torque range.
Tandem Dynamometers are based on the combination of Eddy-current Dynamometers (WB series) and Powder Dynamometers (PB series) mounted in line on a common base and connected by an electromagnetic clutch. Both dynamometers are cooled by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, allowing a power rating up to 140 kW. Both WB and PB Dynamometers integrate a torque measurement system with accuracy ratings of ± 0.3 % to ± 0.5 % full scale, depending on size and system configuration.

Because the characteristics of the WB and PB dynamometers are complementary, Magtrol is able to offer them mounted in a tandem setup. Each dynamometer (WB and PB) can autonomously operate according to its own characteristics (Please refer to specific data sheet).
