MDD090B-N-040-N2M-130GL0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090B-N-040-N2M-130GL0 motor from the MDD Synchronous Motors series is a high-precision motor for digital drive controllers featuring a 090 motor size and B length code. Its integrated multiturn absolute encoder and digital servo feedback (DSF) ensure accurate positioning, while a continuous torque at standstill of 7.2 Nm and a nominal speed of 4000 min⁻¹ deliver consistent performance. The motor’s 130 mm centering diameter and plain shaft design with a shaft seal provide reliable mounting and protection, and its connector-based left-hand connection type facilitates straightforward integration. Provided without a blocking brake, this standard-housing unit balances quality and flexibility for demanding industrial applications.

Frequently Asked Questions
How does the integrated multiturn absolute encoder help on MDD090B-N-040-N2M-130GL0?
It provides absolute position over multiple revolutions that enables immediate reference without homing on power-up. It improves cycle time and prevents cumulative positioning errors in coordinated multi-axis systems.
Why is Digital Servo Feedback (DSF) used here?
The DSF supplies high-resolution position/speed data for the drive to compute precise torque and velocity loops. Its result is smoother interpolation, better following error control and reliable synchronization with other axes.
How is the 4000 min⁻¹ nominal speed utilized in real machines?
It supports high traverse rates and short cycle times in feeders, pick-and-place heads and spindle auxiliaries. The drive must be parameterized for mechanical limits of the load to avoid overspeeding transmission components.
How does the plain shaft with shaft seal benefit this model (MDD090B-N-040-N2M-130GL0)?
The standard keyed/plain shaft simplifies coupling to gearboxes or belt pulleys, while the seal helps guard against ingress at the shaft interface. It supports service life in typical industrial environments.
How does the left-hand, connector-based connection aid integration on MDD090B-N-040-N2M-130GL0?
The side-specific, pluggable power/feedback connectors simplify routing in tight cabinets and speed replacement without rewiring. It is useful for modular machines and mirrored axis layouts.
