Eddy-Current Dynamometers

Magtrol WB series dynamometers
Product Information:

  • Ideal for high speed applications
  • Inceased torque proportional to speed
  • Low inertia
  • Water circulation cooling, allowing for high continuous power ratings (max. 140 kW)
  • Typical accuracy ratings of ±0.3% to ±0.5% full scale, depending on size and system configuration.


Product Description:


Eddy-current dynamometer – Model 2 WB 65 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.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, depending on size and system configuration. Additional options include: high-speed version, speed pick-up, mechanical rotor blocking device, OEM version IS and vertical mounting.
