One or Two directions of rotation

Usually, the dynamometers are designed for one direction of rotation. In this direction, they are adjusted for an optimal torque at different speeds. However, we are also able to supply dynamometers for two directions of rotation. The maximum torque of these is slightly lower than that of the dynamometers with one direction of rotation. In the type designation, the number of directions of rotation is represented by the figure behind the size of the dynamometer. That means that DT700-1 is a dynamometer for one direction of rotation.

Applications

The hydraulic dynamometers are available in different sizes and constructions so that a great variety of combustion engines can be tested, e.g.:

Combustion engines for passenger cars and commercial vehicles
Aircraft engines and turbines
Large engines for trains

Benefits

Robust and long-lasting, even in heavy duty use
Excellent price/performance ratio (Euro/kW) as compared with eddy current dynamometers and AC machines
High quality materials
Simple maintenance due to patented flexure supports
Exceptional control characteristics (torque response times typical 1 sec) when used with HORIBA control unit and power unit
