Product Description:

The MDD090B-N-020-N2M-110PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts electrical power into regulated rotary motion for positioning and speed-controlled operation in automated machinery. Built around motor size 090, it is suited to medium-load axes used in packaging, handling, and tool-change assemblies where stable torque output and accurate feedback are important during repeated motion cycles.

The unit supplies a continuous standstill torque of 7.2 Nm, enabling it to hold static loads without thermal overload during dwell periods. Commands are carried out at a nominal shaft speed of 2000 rpm, which places the motor in a common operating range for industrial servo applications. A blocking brake can exert up to 11.0 Nm to secure the axis when power is removed, and mechanical centering is simplified by a 110 mm pilot diameter. Position and velocity data are returned through digital servo feedback (DSF) together with an integrated multi-turn absolute encoder, allowing high-resolution closed-loop control over repeated moves. The motor also uses a shaft seal to limit lubricant migration, and power and feedback conductors are combined in a single connector. The shaft end is standard, with no extension on the rear side.

Cabling exits toward the controller because the connectors are mounted on Side A, which can simplify routing when the motor is installed in compact machine spaces. The overall length corresponds to length code B, so the motor keeps a compact body size while matching this frame configuration. Torque is transmitted through a keyway shaft, and a standard housing provides the external interface for flange mounting and heat dissipation. Dynamic balancing is standard, which helps support smooth running during extended duty cycles and repeated acceleration changes.
