Product Description:

The MDD093A-N-020-N2M-110GR2 is a synchronous servo motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It converts controlled electrical input from a digital drive controller into repeatable rotary motion for actuators, indexing tables, and handling modules on automated production lines. This arrangement supports accurate torque and speed control in applications that require stable positioning and smooth acceleration.

The motor’s centering pilot is 110 mm in diameter, giving a fixed reference surface for face mounting on gearboxes or machine frames. Cables exit on the right side because the electrical and feedback ports are oriented in that direction, which can simplify routing when the drive is mounted to the left of the axis. Power and signal lines terminate through a sealed connector, so the cable set attaches without individual conductor terminations at the motor housing. At standstill, the magnetic circuit delivers a continuous torque of 9.2 Nm, supporting static load holding and fine positioning without overheating. During motion, the rotor can reach a nominal speed of 2000 rpm, which suits applications that need steady mid-range servo speed.

A blocking brake is integrated and can clamp the shaft with 22 Nm of torque, preventing back-driving when vertical loads remain suspended after power is removed. Position feedback is supplied by an integrated multi-turn absolute encoder, and the drive reads this data through digital servo feedback (DSF) to close the position loop without separate external sensors. The output end uses a plain shaft, and a shaft seal is fitted to help limit dust or coolant ingress at the bearing seat. The motor also uses standard dynamic balancing, a standard housing, motor length code A, motor size 093, and a single-ended shaft without a side B extension to keep the overall length compact.
