MDD093D-N-040-N2L-110GA2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093D-N-040-N2L-110GA2 from the MDD Synchronous Motors series is a high-precision motor for digital drive controllers designed for demanding automation tasks. It features a motor size 093 frame with a motor length code D that balances compact footprint and performance. The unit delivers a continuous torque at standstill of 24.0 Nm and operates up to a nominal speed of 4000 min⁻¹ for rapid acceleration and high dynamic response. Integrated standard balancing ensures low vibration and smooth operation across a broad speed range.
Mechanical resilience is provided by a plain shaft with an integrated shaft seal and a robust standard housing engineered for industrial environments. Safety is enhanced by a holding brake with blocking brake configuration, offering a reliable holding brake torque of 22 Nm to secure loads during power interruptions. Precise alignment is guaranteed through the 110 mm centering diameter and standard balancing tolerances, minimizing mechanical stress on bearings. Connectivity is seamless via a connector on connection direction Side A, while the digital servo feedback (DSF) system delivers deterministic position and velocity data for closed-loop control.
As a dedicated motor for digital drive controllers, the MDD093D series integrates effortlessly into Bosch Rexroth drive networks, leveraging its connector interfaces and high-fidelity feedback. The design’s standard housing, smooth plain shaft, and comprehensive shaft seal protection ensure long service life with minimal maintenance. Whether deployed in packaging machines, material handling systems, or precision tooling, this motor delivers the reliability and performance required for modern automation applications.

Frequently Asked Questions
Does the built-in blocking brake of 22 Nm impose any control-mode restrictions?
Yes: when the brake is applied, the motor’s rotor is held rigid, so the servo loop must disable torque commands accordingly to prevent drive faults. You must sequence the brake release before applying motion commands to avoid hard starts.
How robust is the shaft sealing under industrial contamination?
The integrated shaft seal protects against dust and light splash ingress, but it’s not equivalent to full IP67 sealing; in harsh wet or dirty environments further guards or covers may be needed. Periodic inspection of the seal lip is advisable in aggressive atmospheres.
In B2B/serial production use, what cycle life issues should be considered for this motor?
Repeated brake engagement/disengagement acts like a clutch and can wear the brake friction surfaces over many cycles. Also thermal cycling from frequent startup/shutdown stresses insulation and bearing seals, so plan preventive maintenance.
How does the plain shaft (versus keyed or flanged) impact coupling choices?
A plain shaft allows flexible coupling choices (clamp, shrink disk, or sleeve coupling) but requires precise tolerances and good torque transfer interface. You must ensure key/keyway alignment or friction-fit safety margins when selecting your coupling.
What happens to usable torque if this motor is run near its 4000 min⁻¹ limit?
At high speed, the back-EMF increases and available torque falls roughly inversely, so you’ll see reduced dynamic torque margin. Also thermal constraints may limit continuous torque at high rpm.
