The e range of dynamometers provides a range of eddy – current machines designed for testing engines, Electric Motors and Gear Boxes from 0.75 Kw up to 720 Kw and Torque from 0.5 N-m rated to 5000 N-m Rated Torque. eddy current dynamometers are well known for their stability and suitability to operate in a closed loop mode. These provide precise control even at low loads and rapid changes in demands and provide bidirectional operation.
The rugged design of the power absorbing unit ensures a long operating life, even in the most demanding production and endurance testing environments. The rotor which is in form of a spoke disc results in low inertia. The balanced high rigidity shaft assembly on precision bearings ensures smooth operation. This long life is further enhanced by the nickel plating of critical components in contact with the water.
E series dynamometers feature a rugged design & heavy duty single coil i high quality aluminum bobbin. This ensures high reliability. Speed is measured by a pulse sensor mounted adjacent to a 60 tooth wheel on the coupling while torque is measured by a high accuracy strain gauge load cell mounted between the trunnion bearings, supported casings and bedplate. Control is achieved by varying the excitation current to the coils.
