Modular test field HMP

Function and layout

For investigating different drive train configurations and components hofer has prepared the modular test field HMP. HMP contents various, different electrical motors and centrifugal masses. All can be used for driving the test set-up or producing a certain load.

By usage of different belt transmissions various ratios can be adjusted. By this the requested speed or torque range could be fulfilled.

All components of the HMP are placed on single bed plates, which can be arranged to reproduce the original drive train situation.

Standard measurement technology is implemented and additional measuring equipment can be installed where necessary and requested.
