Dunkermotoren BG42 KI Brushless DC Motor

The Dunkermotoren BG 42 KI is a highly dynamic 3-phase BLDC motor family with an 8-pole neodymium magnet and integrated commutation electronics. It is designed for compact motion systems that need efficient brushless performance, selectable rotational direction, and straightforward electronic integration. The family also features integrated 24 cpr feedback and is built to fit within Dunkermotoren’s modular drive platform.

The BG 42 KI range includes BG 42x15 KI, BG 42x30 KI, and BG 42x45 KI versions in 12Vdc and 24Vdc supply options, with the BG 42x45 KI offered in 24Vdc. Across the family, nominal torque spans from 0.101 Nm to 0.245 Nm, nominal speed ranges from 3,600 rpm to 3,750 rpm, and continuous output power reaches up to 87 W with peak output power up to 226 W. These characteristics make the series suitable for dynamic drive tasks where compact size and responsive performance matter.

The motor family can be combined with encoders and gearboxes within the modular system to support a wide range of geared and feedback-equipped motion solutions. Protection class is rated up to IP40, while the catalogue page shows motor lengths of 65 mm, 80 mm, and 95 mm with motor weights from 0.36 kg to 0.58 kg. This makes the BG 42 KI a strong choice for applications that need modularity, reliable control integration, and high performance in a compact motor package.
