MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090B-N-040-N2M-130PA1 digital AC servo motor from the MDD Synchronous Motors series delivers high-precision motion control optimized for modern automation. This compact yet robust device integrates advanced rotor position and speed control through a built-in encoder system and supports permanent-magnet operation for enhanced efficiency. With a Nominal Speed 4000 min⁻¹ and a peak continuous torque capacity, the MDD090B-N-040-N2M-130PA1 meets the rigorous demands of CNC machining, robotics, and assembly lines. The motor’s digital architecture ensures rapid response and seamless integration into Bosch Rexroth drive networks. Designed and manufactured by Bosch Rexroth Indramat, this motor exemplifies reliable performance in demanding industrial environments.
The MDD090B-N-040-N2M-130PA1 features a comprehensive suite of technical specifications tailored for precision applications. It offers Continuous Torque at Standstill 7.2 Nm and is equipped with a Holding Brake Torque 6.5 Nm blocking brake to secure loads when powered down. The motor’s Centering Diameter 130 mm and Motor Length Code B define its mechanical envelope, while the Motor Size 090 ensures compatibility with standard machine mounts. A high-resolution Encoder Integrated multiturn absolute encoder provides position feedback over multiple revolutions, and Motor feedback Digital servo feedback (DSF) delivers real-time commutation data. Additional critical parameters include Balancing Standard, Housing Standard, Connection Direction Side A, and Connection Type Connector, ensuring consistent mechanical stability and straightforward field wiring.
Operational performance is augmented by a Shaft Type keyway and an Output Shaft Shaft With Keyway Per DIN 6885 sh. 1, 8-68 Edition for secure torque transmission. The motor incorporates Shaft Seal With shaft seal protection to guard against contaminants in harsh factory environments. Its digital control interface supports precise acceleration, deceleration, and speed profiling, while onboard multiturn counting eliminates the need for external homing procedures. Standard balancing minimizes vibration at high speeds, and the lack of a side B shaft end simplifies integration into compact assemblies. These features combine to deliver reliable, high-dynamics performance across repeated start-stop cycles.
Integration into automation systems is streamlined by compatibility with Bosch Rexroth digital drive controllers and existing Indramat infrastructures. The MDD090B-N-040-N2M-130PA1 motor’s standardized mechanical and electrical interfaces reduce engineering effort during system design. Ideal applications include precision robotics, automated assembly, pick-and-place equipment, and CNC tooling spindles, where synchronization and repeatable accuracy are paramount. Its robust digital feedback and fail-safe brake make it a versatile solution for demanding industrial motion control tasks.

Frequently Asked Questions
Why does the motor have a shaft with keyway per DIN 6885 sh. 1?
The keyway per DIN 6885 ensures standardized mechanical coupling and torque transmission between motor shaft and driven components. It helps in reliably transfer of 7.2 Nm continuous torque without slippage under load.
How does the continuous torque at standstill of 7.2 Nm impact applications?
That torque defines how much static load the motor can hold without motion when energized. In contexts like robotic arms or CNC fixtures, it allows the system to resist external forces or gravity without motion even before moving.
How does the digital servo feedback (DSF) interface enhance motor control?
The DSF supplies real-time commutation and rotation feedback to enable closed-loop control of speed and position with low latency. It allows sharper response curves and smoother motion in automated assembly or pick-and-place.
What is the role of the shaft seal protection in harsh environments?
The shaft seal guards against ingress of dust, coolant, or other contaminants into the motor bearings and mechanical internals. It helps maintain reliability and reduces wear in factory settings with exposure to fluids or particulate matter.
Why does the motor not include a shaft end on Side B (“without side B shaft end”)?
The omitting of a shaft extension on side B simplifies mounting in applications where back side access or coupling is not needed to saving space and potentially reducing cost. It streamlines installation in compact drive modules or machine frames.
