Product Description:

The MDD090B-N-020-N2M-110PR1 is a synchronous servo motor built by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical energy delivered by an inverter into precise rotary motion for closed-loop machine axes. This supports positioning, indexing, and speed-regulated movement in industrial automation cells where repeatability is required during continuous operation.

At standstill, the rotor can deliver a continuous torque of 7.2 Nm, allowing the axis to maintain load without overheating. During operation, the windings are set for a nominal speed of 2000 rpm, so a matching drive can use the available power across the typical velocity band used in transfer lines and handling modules. Mechanical integration is simplified by the 110 mm centering diameter that fits the standard flange pattern, while assembly wiring is routed through a sealed connector on the motor's right side. This layout helps align the housing and keeps cable entry on one side of the motor. The housing and balancing are standard. The shaft uses a fitted seal to limit contamination ingress, and size code 090 with length code B sets the overall geometry. A single-ended shaft without a side-B extension is provided to minimize envelope depth.

For static holding or emergency stops, the integrated brake supplies 6.5 Nm of holding torque, permitting vertical or suspended loads to remain secure when the inverter is disabled. Position monitoring relies on the integrated multi-turn absolute encoder, which records shaft angle over multiple revolutions and removes the need for homing cycles. Closed-loop control signals return to the drive via digital servo feedback, enabling high-resolution torque and speed regulation with consistent phase alignment during repeated motion. Power transmission to the load is handled by the keyed shaft specified as a keyway, matching standard couplings and gears used on packaging machines and gantry axes.
