Brushless DC Motors

Dunkermotoren BG 66 dCore Brushless DC Motor

The Dunkermotoren BG 66 dCore is a highly dynamic 3-phase EC motor with a 10-pole neodymium magnet, Hall sensors for rotor position detection, and a high-resolution magnetic encoder MR 1 providing 4×1,024 pulses per revolution (4096 cpr). The motor features a One-Connector-Solution for simplified connectivity. Available in BG 66x25, BG 66x50, and BG 66x75 stack lengths with supply voltage options from 12 Vdc to 110 Vdc, the series delivers continuous output power up to 359 W and peak output power up to 838 W.
