Brushless DC Motors

Dunkermotoren BG 75 dCore Brushless DC Motor

The Dunkermotoren BG 75 dCore is a highly dynamic 3-phase EC motor with an 8-pole neodymium magnet, Hall sensors for rotor position detection, and a high-resolution magnetic encoder MR 1 (4×1,024 pulses per revolution, 4096 cpr). The motor uses a One-Connector-Solution for simplified connectivity. Available in BG 75x25, BG 75x50, and BG 75x75 stack lengths with supply voltage options from 12 Vdc to 325 Vdc, the series delivers continuous output power up to 546 W and peak output power up to 1,150 W.
