Product Description:

The MDD090B-N-020-N2L-110GL0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive output current into precise shaft rotation for industrial positioning and velocity control. The rotor is dynamically balanced to the standard grade, allowing smooth operation within tight vibration limits required on automated axes. This configuration is suitable for motion systems that require stable servo response during repeated start-stop cycles and consistent speed control under changing loads.

This model delivers a continuous stall torque of 7.2 Nm, giving machines steady holding force during low-speed or static phases. Its nominal speed is rated at 2000 rpm, matching drives that regulate medium-speed production lines without overspeeding the magnetic circuit. A centering diameter of 110 mm simplifies concentric mounting on gearboxes or flanges, while the connections emerge on the left side through a sealed connector interface that can shorten cable runs inside cabinets. Position feedback is provided by integrated digital servo feedback, so the drive can close high-resolution loops without external encoders. The plain shaft is protected by a radial shaft seal, and the housing and winding set use the standard thermal envelope for this motor size.

The unit is supplied without a blocking brake, which reduces mass where passive holding torque is unnecessary. It uses a plain shaft with no side-B extension, which suits couplings that rely on a single output end and a standardized keyless profile that minimizes fretting under reversing loads. The frame corresponds to size 090, and the B length code gives moderate rotor inertia for mid-range load inertia ratios. A standard housing encloses the windings, and internal passages align with the connector type used across the MDD line. This layout supports installation where compact cable routing and a single shaft end are preferred.
