Product Description:

The MDD090B-N-040-N2M-110PA1 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves as the rotary actuator in packaging machines, handling stations, and other servo axes that need closed-loop speed and position control. Its 090 frame size with B length code gives the motor a consistent installation envelope, and the standard housing supports straightforward integration where matching mechanical dimensions are required across related axes. It is intended for applications that rely on repeatable servo response, because the motor works with controllers that continuously correct speed and position during operation.

During operation, the motor supplies a continuous torque of 7.2 Nm at standstill, which supports steady load holding without forced cooling. The rated speed is 4000 rpm, and accurate mechanical centering is provided by a 110 mm flange diameter that fits common mounting faces. Cables exit on side A, and a sealed connector interface allows electrical connection without leaving fixed leads attached to the housing. This arrangement helps with cable routing when surrounding machine structure limits access around the motor body. A shaft seal also helps protect the front bearing area from coolant or dust, while the single drive-side shaft end keeps the overall motor form compact.

For static holding, the integrated blocking brake applies 6.5 Nm of torque when power is removed, which helps keep the axis from drifting at a standstill. Motion feedback is provided by an integrated multi-turn absolute encoder, and position data return to the controller through Digital servo feedback (DSF) for closed-loop control. Absolute feedback preserves position information over multiple revolutions, which reduces the need for reference moves after restart. Power is transmitted through a keyway shaft that matches common keyed couplings used in servo drive trains. This shaft and feedback arrangement supports precise rotary motion while maintaining a practical mechanical interface for machine integration.
