Driving motor for transaxle testing

摘要

Meidensha Corporation has long been manufacturing the driving equipment, which can be substituted for a car engine, to promote the R&D activities and testing on a variety of units and associated components of the power transmission (power train) systems. In 1997, the company developed and put into production an ultra-small-diameter permanent magnet type dynamometer (PMDY), offering a gearless feature. The use of the PMDY was really effective in the simplification of the overall system layout, but it left out a different matter of layout simplification for the transaxle test that is exclusively related to the front wheel drive (FWD) transmission. In order to solve this matter, we have developed an ultra-small-diameter type dynamometer for the transaxle test (PCDY: Pencil Dynamometer). This equipment, to be introduced below, enables the direct coupling and driving of a transaxle without the use of any offset gears.
