Product Description:

The MDD090A-N-020-N2L-130GR2 is a brushless synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, this unit supplies controlled torque and speed for positioning tables, gantries, and handling modules in industrial automation. By accepting continuously modulated phase currents from a servo inverter, it generates a rotating electromagnetic field that couples with the rotor magnets to deliver responsive, closed-loop motion. This operating principle helps the drive maintain accurate acceleration, steady holding behavior, and repeatable positioning during frequent motion cycles.

A centering diameter of 130 mm aligns the stator housing to machine frames, while standard ISO balancing minimizes vibration through the rated operating range. Power and encoder leads exit on the right side through a sealed connector, which helps simplify cable routing in compact machine layouts. At standstill, the motor can deliver a continuous torque of 3.7 Nm, and it maintains synchronous operation up to a nominal speed of 2000 min⁻¹. The standard housing and the size 090 frame help dissipate heat so this torque can be sustained without forced cooling. This supports steady operation during repeated starts, stops, and speed changes.

The integrated blocking brake exerts 11.0 Nm of holding torque to secure vertical or overhung loads when power is removed. Position data is returned through digital servo feedback (DSF), giving the drive exact rotor angle for tight current loops and consistent speed regulation. A plain shaft with a shaft seal protects internal bearings from coolant or oil ingress, and the standard shaft end on side A eases coupling to pulleys or pinions. Motor length code A and the standard housing keep overall mass moderate, allowing the 090 frame to be installed in multipurpose axes that require quick inertia matching without exceeding common space limits.
