MDD071B-N-030-N2L-095PB0
The MDD071B-N-030-N2L-095PB0 is a synchronous motor for digital drive controllers produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as a rotary actuator in automated handling, packaging, and machining stations, where closed-loop drives command speed and position through high-resolution feedback. When paired with a compatible drive, the unit delivers controlled torque across its operating range and supports fast indexing cycles in multi-axis assemblies. The motor uses permanent magnets and a compact housing arrangement suited to repeated starts, stops, and direction changes in industrial motion systems.
The centering pilot of 95 mm establishes a mechanical datum that keeps the motor aligned with the machine frame during installation. Accurate centering helps keep shaft loading consistent and supports smooth coupling to the driven mechanism. At standstill, the unit supplies 4.4 Nm continuously, which supports load holding and slow-feed movement without thermal overload. Under rated excitation, it reaches 3000 rpm, making it suitable for medium-inertia axes that require quick reversals and stable speed control. Rotor position is returned through digital servo feedback, giving the controller precise motion data for tight velocity and position loops. This feedback path lets the controller correct load disturbances quickly during acceleration and steady running. Power and signal plugs face Side B, which helps keep cable routing clear of couplings or gearheads on the drive end.
A keyed shaft uses a keyway to transmit torque securely to external transmission elements. This shaft style is useful where a pulley or coupling must hold its angular relationship under changing load. The output journal is protected by a shaft seal, which helps block lubricant migration and airborne contaminants in normal industrial environments. Electrical terminations use a compact Connector format that keeps the housing interface tidy and supports straightforward cable attachment. With a frame coded as 071, the motor matches standardized mounting patterns used in this product line. The motor does not include a holding brake, which reduces mass where dynamic stopping is handled by the drive or by the machine. Standard balancing supports smooth rotation across normal industrial duty cycles.
