Ultra-low Inertia Dynamometer (PMDY)
Inverter Ultra-low Inertia
Dynamometer (PMDY)

1 This type of dynamometer has the moment of inertia, which is almost the same as that of an automobile engine. Thereforem, it can be used in place of an automobile engine when testing the power train system. For a dynamometer of 220kW 5000/8000min-1, the moment of inertia is 0.1kgm².
2 This dynamometer uses permanent magnets to achieve high efficiency. This contributes to down-sizing and energy conservation.
3 Great improvement has been achieved to reduce torque ripples.
4 Both the water cooling system and the air cooling system are used to reduce operation noise.
5 The VT330DY-PM Series is available. This series offers inverters that incorporate the IGBT devices, and it performs vector control by the use of permanent magnets.
6 The capacity : 200kW & 330kW
