Eddy Current DynamometersThe Air Gap range of Eddy Current Dynamometers has been designed to be compact, robust and to allow easy maintenance. Each Eddy Current 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. DescriptionThe Air Gap range of Eddy Current Dynamometers has been designed to be compact, robust and to allow easy maintenance.

SpecificationThe standard AG dynamometer range extends from 30 kW to 750 kW at speeds up to 12,000 rpm and can absorb power in either direction of rotation. Torque measurement accuracy is ±0.25% of full rated torque of the dynamometer. The speed is measured by a pulse pickup operating with a 60 tooth wheel and gives accuracy of ±1 rpm.
Froude dynamometers are painted traffic blue RAL 5017. |
