Eddy Current Engine Dynamometers

The Air Gap range of Eddy Current Dynamometers has been designed to be compact, robust and allow easy maintenance. Each dynamometer is fitted with oil injected half couplings at either end of a non-magnetic stainless steel shaft which is supported in grease lubricated, deep groove ball bearings. The dynamometer casing houses twin magnetising coils that produce a retarding controllable magnetic field that resists the applied torque. Heat generated in this process is dissipated by cooling water.

Rotation of the casing is resisted by a precision strain gauge load cell that gives accurate measurement of total input torque.

Main Features:

  • Torque measurement accuracy ±0.25% of full rated torque of dynamometer
  • Speed measurement accuracy ±1 RPM
  • Low inertia 
  • Bi-directional 
  • High reliability 
  • Easy maintenance
