Product Description:

The MDD093A-N-030-N2M-130PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit supplies controlled rotary motion to indexing tables, packaging stations, and handling modules. Its 093 size frame and standard housing allow direct installation in tight machine enclosures, while the internal windings accept the high dynamic current setpoints required for accurate acceleration, deceleration, and point-to-point positioning tasks within automated production lines.

At standstill, the motor can deliver a continuous torque of 9.2 Nm, permitting long-duration holding or slow-speed feed without overheating. When commanded, the rotor reaches a nominal speed of 3000 rpm, matching the output range of common Rexroth power modules. For emergency locking or gravity-loaded axes, the integrated blocking brake applies up to 11 Nm of static torque as soon as supply power is removed. Rotor position and velocity are returned to the drive through digital servo feedback (DSF), enabling high-bandwidth current loops. A centering shoulder of 130 mm aligns the flange with machine faces. Standard dynamic balancing, a connector-based side B cabling orientation, and a keyed single-ended shaft complete the mechanical interface.

The position loop is reinforced by an integrated multi-turn absolute encoder, allowing the axis to recover exact angular data after power loss without an external homing cycle. Torque is transmitted through a shaft with a keyway, simplifying hub coupling and resisting slippage during rapid reversals. To protect the front bearings, a shaft seal is fitted so contaminants do not reach the internal lubricant. The build is identified by length code A, the shortest variant for the 093 family, which minimizes stack length and rotor inertia while preserving the mounting footprint.
