Product Description:

The MDD093D-N-020-N2M-110PB1 is a three-phase synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into rotary motion for positioning and velocity control in industrial automation. Its synchronous design supports accurate speed regulation and repeatable positioning on packaging, handling, and machine-tool axes. When paired with a compatible digital controller, the motor can respond quickly to load changes and maintain stable motion during repeated cycles. The housing is the standard uncooled variant, so heat is dissipated without an added fan or liquid circuit.

This D-length unit can deliver a continuous standstill torque of 24.0 Nm, which supports holding and low-speed feed tasks without overheating. With matched drive current, the rotor reaches a nominal speed of 2000 rpm under rated load. The motor uses frame size 093 with D length for this torque class, and standard dynamic balancing helps limit residual vibration. For cabinet wiring, power and feedback connections are oriented on side B and use a connector plug set. This arrangement keeps the cable exit grouped on one end of the housing and can simplify routing in compact machine spaces. A mechanically integrated blocking brake provides 11 Nm of holding torque when drive power is removed.

Control loops receive rotor position through digital servo feedback (DSF), and an integrated multiturn absolute encoder retains position data through power cycles. This feedback arrangement allows the controller to monitor rotor angle continuously during indexing, feed, and positioning moves. Installation is centered by a 110 mm pilot diameter that aligns the motor with adjacent machine components. Torque is transferred through a keyway shaft, and a factory-installed shaft seal helps protect the bearing area from coolant splash and airborne dust. The primary shaft end follows the standard geometry, while the reverse side remains blank to avoid overhung load on auxiliary equipment.
