Product Description:

The MDD093A-N-030-N2M-110GR1 is a three-phase synchronous motor in the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Designed for digital drive controllers, it provides closed-loop positioning and velocity control for automated machine axes, conveyors, and material-handling stations. The unit integrates a multi-turn absolute encoder for direct feedback to the drive, allowing interpolation-quality motion while eliminating external sensors. That feedback lets the controller track rotor position through multiple revolutions and maintain smooth motion during reversing moves. With its 093 frame size and compact length code A, the motor fits installations where moderate continuous torque is needed without enlarging the mechanical envelope.

A centering shoulder of 110 mm aligns the flange accurately on the machine frame, so runout remains minimal. At standstill, the magnetic circuit delivers 9.2 Nm of continuous torque, allowing table or gantry loads to be held without overheating during dwell periods. When driven by a suitable inverter, the rotor can reach its rated speed of 3000 rpm, giving balanced performance between feed rate and positioning precision. Power and feedback conductors exit on the right side through a sealed connector. This layout keeps the cable interface compact and supports a protected connection at the housing.

A blocking brake supplies 11 Nm of holding torque to secure vertical or suspended axes when power is removed. Position data is transmitted as digital servo feedback, allowing the controller to detect rotor angle without a homing cycle after startup. The motor has a plain shaft with a shaft seal, which helps keep lubricants or coolant from migrating into the stator cavity. Side B remains closed because the model does not have a second shaft end. The motor also uses standard balancing to reduce vibration during operation.
