2 Pole Brushed Coreless Micromotors

ATOM DC Series

The specific design construction of a coreless DC motor provides several advantages over traditional, iron-core, technology. A first added value is given from the rotor’s lower mass and inertia, so very rapid acceleration and deceleration rates are possible. Furthermore, the lack of iron reduces “iron losses” to provide higher efficiencies (up to 90 percent) than traditional DC motors. Last, but not least, the coreless design reduces winding inductance, so sparking between the brushes and commutator is reduced, increasing motor life and reducing electromagnetic interference (EMI).
Servotecnica’s Coreless DC Motors are available in a wide range of sizes and have high flexibility on mechanical custom requirements.
