Ingersoll Rand Hybrid Permanent Motor (HPM)

Uploaded by: grizz708
Video Description:
The Nirvana HPM system is not only ultra-efficient and reliable, but is also designed to enable limitless starts and stops to meetdemand, without the risk of damaging itself. This type of motortechnology is often used in elevators, where safety, efficiency, andreliability are vital concerns. Frequent starts and stops is a problem for conventional induction VSD compressors — doing so causes heat problems and insulationbreakdown. When they do start up, these compressors requirea power surge of up to twice full-load current in order toovercome initial inertia. This generates excessive heat andlimits the operating pattern of the compressor. Induction VSD compressors also run unloaded when demand is belowminimum, reducing efficiency and driving up energy costs.The Nirvana HPM, on the other hand, requires less power at start-up, never operates at more than full-load amps, and shuts downimmediately at minimum speed to avoid wasted energy. Nirvanaensures constant pressure throughout the entire operating range.
