MDD090C-N-030-N2L-110PB1
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090C-N-030-N2L-110PB1 is a high-performance motor in the MDD Synchronous Motors series designed for precise digital drive controller applications. This motor features a robust continuous torque at standstill of 10.4 Nm and an integrated holding brake with a blocking brake torque of 6.5 Nm, ensuring stable operation and secure load holding when powered down. Its nominal speed of 3000 min⁻¹ and standardized motor feedback system enable accurate positioning and speed control in demanding industrial environments.
Built with a motor size of 090 and motor length code C, the MDD090C-N-030-N2L-110PB1 maintains a compact footprint while delivering reliable power. The motor housing is optimized for durability with a standard housing and shaft seal to protect internal components from contaminants. A precision centering diameter of 110 mm and shaft type keyway provide secure coupling to machinery. Connectivity is streamlined via a side-mounted connector on Direction B, and digital servo feedback (DSF) ensures seamless integration with modern control systems. The motor end configuration is standard, omitting any side B shaft extension to simplify installation.
Further enhancing its versatility, the motor employs standard balancing to minimize vibration and extend bearing life under continuous operation. Compatibility with Bosch Rexroth Indramat digital drives is inherent, and the connector interface reduces wiring complexity. The inclusion of a blocking brake enhances safety by preventing unintended motion during power loss, contributing to overall system reliability. As a purpose-built motor for digital drive controllers, this unit improves system efficiency, reduces downtime, and offers the precision and durability required for advanced automation and high-throughput industrial applications.

Frequently Asked Questions
What is the impact of its continuous torque at standstill (≈10.4 Nm) on machine design and safety margins?
This torque defines how much load the motor can hold without motion at zero speed; for lift or vertical applications, you must ensure the holding or blocking brake can safely counteract external forces exceeding this torque. Using a safety factor (e.g. 1.5–2× of maximum expected torque) is common to avoid overload during unexpected moments.
How does the integrated blocking brake (6.5 Nm) influence stop-motion behavior and safety in power-loss situations?
The brake will engage when power is removed to hold the load; but its 6.5 Nm torque limits how much static load can be safely held without drift. For applications with heavier loads or steep inclines, additional mechanical locking or oversizing may be required.
How does the nominal speed of 3000 min⁻¹ affect thermal management and cooling requirements?
At 3000 rpm continuous operation creates significant heat in rotor/stator and bearings; natural convection cooling (as standard housing) may suffice for moderate loads but higher duty cycles or ambient temperatures may require forced cooling or derating. Exceeding temperature limits without adequate cooling can drastically shorten insulation life.
What role does Digital Servo Feedback (DSF) play in performance, and what are the limits (cable length, resolution)?
DSF provides high resolution, fast feedback for precise speed/position control; however, Bosch recommends maximum feedback cable lengths (e.g. up to ~75 meters) to avoid signal degradation. Excess cable length or poor shielding increases risk of noise, latency, or oscillations in the control loop.
What is the significance of the shaft seal and standard housing for environmental protection and maintenance?
The shaft seal helps prevent ingress of dust, particles, and potentially liquids, thereby keeping internal parts (bearings, windings) cleaner and prolonging lifespan; standard housing is typically rated for industrial environments but may not provide full IP65 or higher protection. For harsh environments, one might need to verify IP rating or add protective covers.
