MDD090B-N-030-N2M-110PR0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090B-N-030-N2M-110PR0 from the MDD Synchronous Motors series delivers precision digital servo performance with a motor size 090 frame and motor length code B. This permanent-magnet AC servo motor is built with a standard housing and features an integrated multiturn absolute encoder to provide reliable digital servo feedback (DSF) for commutation, rotor position, and speed control. Engineered as a motor for digital drive controllers, it utilizes a robust standard balancing design and includes a shaft seal to guard against contamination. With a compact centering diameter of 110 mm and a standard (without side B shaft end) shaft end, this unit simplifies mechanical integration and alignment.
The motor delivers a continuous torque at standstill of 7.2 Nm and spins at a nominal speed of 3000 min⁻¹, making it ideal for high-dynamics applications. Its shaft type keyway per DIN 6885 sh.1, 8-68 Edition, ensures positive torque transmission, while the connector connection type and right connection direction streamline installation and wiring. Supplied without blocking brake, the design remains lighter while accommodating external braking solutions as needed. The rugged build and precision encoder stabilize control loops and enhance repeatability under rapid acceleration and deceleration cycles.
Bosch Rexroth Indramat’s MDD090B model excels in applications demanding fine speed regulation, torque accuracy, and low maintenance. The combination of a multiturn absolute encoder system and digital feedback loop maximizes throughput and minimizes tuning time. As a component of the MDD Synchronous Motors series, it supports modular automation architectures and integrates seamlessly with Rexroth drive controllers for turnkey performance.
