Dynomet Roller Dynamometer  for cars

 

The Dynomet Roller Dynamometer works on the same principle as the Dynomet 3.11
Instead of accelerating/decelerating the weight (the mass) of the vehicle you accelerate/decelerate the rotation mass of the rollers and the connected flywheel.
The software is the same as being used for the  Dynomet 3.11 but adjusted to rollers
 
 

 
 
  The Dynomet Roller Dynamometer facilitates a fast and accurate power test done in the workshop.

The result is shown as two graphs showing the hp (or kW) against rpm and Nm against rpm. Displayed on the monitor or printed out in black/ white or in color. see  Dynomet 3.11

 

Our latest model has very large rollers allowing better contact between tyres and rollers, and thanks to the very large dimensions of the unit it is possible to accommodate small trucks.

An electric retarder can be added to test engines under load, which is necessary for fault finding procedures. Because of the large roller dimensions the flywheel is not necessary, and there is therefore now nothing protruding above floor level. It is possible to build in a retarder in the middle of the unit, which is prepared for this addition. If necessary, it is therefore possible to split up the investment in two.

In the software you can set a fixed speed / Rpm and measure the power for that speed
