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 a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing 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. Features o13 Models with Maximum Torque from 300 mN•m to 560 N•m (42 oz•in to 413 lb•ft) oBraking Power: from 500 W to 140 kW oStable Braking Torque, without Shock oLow Moment of Inertia oLow Residual Torque oOperating Direction CW / CCW oBraking Torque Measurement Integrated oHigh Rotational Speed oIntegrated Optical Speed Sensor oSpecial designs available upon request Operating Principles The WB Eddy-Current Dynamometers develop their full power at high rotation speeds. The WB Series is particularly intended for motors which rotate at high speeds, up to 65 000 rpm (up to 100 000 rpm with WB 23 / 27; see specific datasheet). The braking torque depends on the rotation speed.
