Complete servo drive NPFM.654663.001 is intended to drive various servomechanisms including of on-board ones for aircrafts of general and special purpose.
The complete servo drive includes:
- servocontroller (control module NPFM.426471.001);
- synchronous servo motor with built-in absolute encoder and electromagnetic brake (power module NPFM.435151.001);
- associated cables (on request).
Communication of servo drive with master controller is carried out via interface RS-485 with protocol ModBUS RTU or via interface CAN.
Control module is operable under environmental climatic and mechanic factors for group 1.7.3 according to Russian State Standard ГОСТ РВ 20.39.304-98, including in temperature range minus 50 °С to plus 65 °С.
For power module the operational temperature range is minus 40 °С to plus 70 °С.
In base configuration synchronous electric motor ДСМГ-0,04-50-1-Т-Д-У3 manufactured by «Kaluga electro-mechanical plant» is used.
