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 a water
circulation system, which passes inside the stator to dissipate
heat generated by the braking power. The water cooling in the
WB provides high continuous power ratings (max. 140 kW). The
WB dynamometers have accuracy ratings of ± 0.3% to 0.5% full
scale (± 2% for WB 2.7), depending on size and system configuration. Additional
options include: high-speed version, speed pickup, mechanical
rotor blocking device, OEM version IS and vertical mounting.
Magtrol offers Eddy-Current and Powder Dynamometers mounted
in tandem. In tandem, the unique features of each type of dynamometer
brake are utilized, allowing the unit under test to be applied
with nominal braking torque from zero speed to maximum rotation.
The Tandem Dynamometers are available on a number of PB/WB combinations.
