Application for Testing DC Motors in Four Quadrants

The paper presents a DC Test Bench Drive which comprises 4 test units. These can be coupled two by two to test two DC motors one in the starter and another in generator state. The regulation algorithm and how transmit the information needed for the regulation is the original aspect of this paper. Innovative aspects of the proposal are: bidirectional speed multiplier; non-contacting measuring of torques and speeds; use of specialized software for complete system configuration and management.
