Product Description:

The MDD093C-N-040-N2L-110GL0 is an AC synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as a motor for digital drive controllers, transforming commanded current into precise rotary motion for positioning axes and indexing tables. In closed-loop motion systems, it supports accurate speed changes and repeatable position control during frequent start-stop cycles. A standard housing protects the stator windings, and standard dynamic balancing keeps vibration within ISO limits without extra counterweights. Because the unit is supplied without a blocking brake, external holding methods are required when the shaft must remain fixed during power-off conditions.

The motor’s centering pilot is 110 mm, allowing rigid, concentric coupling to a gearbox or flange to minimize runout. Its nominal operating speed is rated at 4000 rpm, giving adequate headroom for high-throughput pick-and-place or spindle applications that need repeatable velocity tracking. Power, encoder, and protective earth conductors exit on the left side, which can simplify routing in cabinets that place the drive hardware on the right. A keyed circular connector interface handles both power and feedback lines, reducing cable handling during installation and service. Position data travels through digital servo feedback (DSF), so a compatible drive can close the speed and position loops with high resolution and low latency.

The frame follows size code 093, while the stator stack uses length code C, producing a torque profile suited to midsize gantries and material-handling actuators. There is a shaft seal that helps keep contaminants away from the bearing area and limits lubricant migration from adjacent mechanical components. A plain shaft without a keyway reduces stress concentrations, and the design omits a side-B extension so couplings attach only at the front end and the overall motor length stays compact.
