UMD uninterruptible motor drive
UMD provides uninterrupted power for standard AC motors. UMD supplies
motor drives with full power and rpm at all times, even if there is a
mains power failure.
UMD provides new opportunities for safeguarding critical
drives in demanding applications, where disturbances in mains supply
may cause fall in production or damage of equipment.
| Example of applications |
| • Gasturbines,
lube oil pumps, oil mist fan, cooling pumps, IGV, barring |
| • Gascompressors,
lube oil pumps, cooling pumps, cooling fans |
| • High voltage AC-motors,
jacking oil |
| • HVAC, compressor, fan, heaters |
| • Ex(p) safe area, fans for dilution with air in hazardous areas |
| • Hydropower plants, control of dam gates, drain pumps, intake valve |
| • Smelting plant, motion control for lifting and tilting, conveyor
belts |
| • Boilers, cooling pumps |
| Benefits of UMD |
| • Standard AC motor can be driven using battery back-up |
| • Makes the ordinary drive system uninterruptible, eliminating
the need for a DC motor standby system |
| • Simple and flexible: one AC input; as many outputs as required;
each output is an inverter with versatile control opportunities and
complete protection for wiring and motor |
UMD is available in two variants, with built-in DC system, or for supply
from an external DC system:
