Product Description:
The MDD090B-N-040-N2M-110GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated current from the drive into precise rotary motion for positioning tables, feed axes, and packaging spindles in automated machinery. The integrated blocking brake keeps the load immobile when power is removed, which is useful on vertical axes or during controlled stops. Its standard housing suits installation inside enclosed machine sections without requiring a separate protective enclosure.
The motor’s rated operating speed is 4000 rpm, so it can run continuously at that rotational velocity when matched with the correct drive. At standstill, it produces 7.2 Nm of continuous torque, which supports holding force without overheating the windings. During emergency stops or vertical-axis parking, the brake supplies up to 11.0 Nm of holding torque, reducing the need for external holding hardware. A centering diameter of 110 mm provides a precise reference surface for flange alignment against the machine frame. All power, feedback, and brake conductors exit on the right side through a keyed circular connector, which helps keep cable routing orderly in multi-axis assemblies.
Position data are measured by an integrated multi-turn absolute encoder, which reports shaft position over multiple revolutions and removes the need for a homing cycle at startup. The drive reads that data as digital servo feedback, enabling closed-loop speed and torque control with high positional accuracy. A plain shaft permits direct coupling through clamp or bell housings, and a factory-installed shaft seal helps block coolant spray from entering the front bearing area. Dynamic imbalance is minimized through standard balancing, which helps keep vibration controlled at higher speed. This encoder and shaft arrangement is suitable for indexing tables, pick-and-place heads, and other axes that must restart with retained position information.
