Brushless DC Motors

Dunkermotoren BG 75 dPro CO/IO Brushless DC Motor

The Dunkermotoren BG 75 dPro CO/IO is a 3-phase EC motor with an integrated 4Q servo controller featuring field-oriented control (FOC) and sinusoidal vector control. The integrated magnetic encoder MR 1 with 4096 cpr enables high positioning accuracy and an extended usable speed range. Available in BG 75x25, BG 75x50, and BG 75x75 stack lengths with 12 Vdc, 24 Vdc, and 48 Vdc supply options, the series delivers continuous output power up to 807 W (thermally connected) and peak output power up to 1,317 W.
