This is a variable speed dynamometer, capable of both motoring and absorption duty. In case of absorption duty, the power absorbed by the prime mover under test is absorbed in the load bank. The load control is obtained partly by armature control (coarse) and partly by field control (fine). For motoring duty, a variable voltage D. C. Power source is required. Speed control is obtained partly by voltage control (coarse) and partly by field control (fine).
|Universal D. C. Dynamometer.|
A universal D. C. dynamometer is an ideal tool for the Research and Development work. A typical application of universal dynamometer is in measuring Frictional Horse Power of I. C. engines.
