MDD090A-N-020-N2L-110GL0
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD090A-N-020-N2L-110GL0 from the MDD Synchronous Motors series is a precision-engineered digital AC servo motor designed for demanding automation applications. Featuring a motor size 090 frame and a motor length code A, this unit delivers reliable performance with a nominal speed of 2000 min⁻¹ for high-dynamic positioning tasks. Its construction includes a plain shaft with a standard (without side B) shaft end, allowing straightforward mechanical coupling. Manufactured by Bosch Rexroth Indramat, this motor embodies the brand’s reputation for robust design and precision control.
This servo motor incorporates a digital servo feedback (DSF) system that provides accurate commutation, rotor position, and speed control without compromise. The continuous torque at standstill of 3.7 Nm ensures dependable holding power in stop-and-hold modes, while the shaft seal and housing: Standard configuration protect internal components from contaminants. Connectivity is simplified via a left-oriented connector with connection direction: Left, facilitating streamlined installation in compact drive cabinets. Balanced to standard specifications and supplied without blocking brake, the unit offers a clean inertial profile and minimal vibration at full speed.
Engineers will appreciate that the centering diameter of 110 mm aligns with established mounting patterns, reducing integration time and allowing direct replacement of legacy motors. As a dedicated motor for digital drive controllers, this MDD model pairs seamlessly with Rexroth Indramat drives to enable rapid commissioning through auto-configuration of encoder parameters. The result is a highly adaptable servo solution that maximizes machine uptime, improves throughput, and sustains precise control in cutting, packaging, and indexing applications.

Frequently Asked Questions
What impact does the 27.7 mH windings inductance have on signal processing?
The 27.7 mH windings inductance introduces a lag in the motor's response to rapid control signals, affecting high-frequency operations and limiting the motor's performance in fast, precision-demanding applications.
Why is the housing design, suited for natural convection and surface-cooling, critical for performance?
This design ensures that heat generated during operation can dissipate naturally, reducing the need for active cooling. However, it may require external cooling in higher load or continuous duty cycles.
How would a theoretical maximum torque of 19.0 Nm influence load-bearing capacity?
A maximum theoretical torque of 19.0 Nm ensures that the motor can handle substantial loads, making it suitable for systems requiring consistent power and torque output without risking mechanical failure.
What effect would the 0...+45°C permissible ambient temperature have on the MDD090A-N-020-N2L-110GL0 motor’s heat management?
The motor’s performance is optimized within the 0...+45°C temperature range. Exceeding this range could lead to overheating, reducing efficiency and potentially shortening the motor's operational life if not properly managed.
How does the windings resistance of 6.84 Ohms influence current handling?
The 6.84 Ohm windings resistance affects the motor's current handling by creating resistive losses, increasing heat generation during high currents and potentially reducing overall motor efficiency at higher loads.
