Read MoreThe Dunkermotoren BG 45 dCore is a highly dynamic 3-phase EC motor family with an 8-pole neodymium magnet and Hall sensors for rotor position detection. It is offered in two motor lengths and comes as a standard plug version, making it well suited to compact motion systems that need precise rotor feedback, reliable brushless operation, and straightforward integration with external control electronics.
The BG 45 dCore family includes BG 45x15 dCore and BG 45x30 dCore variants in 24Vdc and 48Vdc versions. Across the range, nominal output power reaches up to 118 W when thermally connected, while peak output power reaches up to 187.3 W. The family also provides integrated 24 cpr feedback, premium efficiency, protection class up to IP65, and supply voltage versions covering 6Vdc to 48Vdc depending on configuration.
Within the Dunkermotoren modular system, the BG 45 dCore can be combined with controllers, encoders, brakes, planetary gearboxes, angular gearboxes, and IP65 cover accessories. The datasheet page also notes connection cable lengths up to 3 m as standard, with longer cables up to 10 m available on request, making this motor family a strong option where compact installation, modular drive design, and higher environmental protection are important.
