The MDD series R911256215 (MDD090A-N-030-N2L-110GA1) is a compact synchronous servo motor by Bosch Rexroth, capable of delivering high contouring accuracy at rapid feed rates. This efficient motor operates at a nominal speed of 3,000 rpm, reaching a peak torque of 17.7Nm. Its rotor, comprised of iron oxide and rare-earth magnetic materials, results in low inertia and a favorable torque-to-inertia mass ratio. Its robust bearing has a service life of 30,000 operational hours and is self-lubricating, allowing for maintenance-free operation. Heat dissipation is achieved through surface cooling and natural convection, enabling high-frequency start-stop operations. With its digital servo feedback encoder, system accuracy is maintained at ±0.5 angular minutes. Additionally, its data memory aids in reducing start-up time and ensuring secure adaptation to the drive controller. This product is sealed under IP 65 protection class, safeguarding it from solid objects and water sprays.
