Product Description:

Bosch Rexroth Indramat manufactures the MDD093A-N-040-N2M-110GA2 synchronous servo motor, a member of the MDD Synchronous Motors series. This model works with digital drive controllers to provide tightly regulated rotary motion for automated conveyors, pick-and-place modules, and general machine-tool axes. By combining permanent-magnet excitation with electronic commutation, the unit converts commanded three-phase current into controlled speed and torque under closed-loop operation. It is intended for applications that need repeatable positioning and stable response during frequent starts, stops, and speed changes.

The motor is rated for a nominal speed of 4000 rpm, which is its maximum continuous rotational speed under rated operating conditions. At standstill, it can apply 9.2 Nm of continuous torque, allowing the axis to hold load without overheating under rated current. A built-in blocking brake delivers up to 22 Nm so vertical or safety-related axes remain fixed when power is removed. Position and velocity data are returned to the drive through digital servo feedback, and the signal comes from an integrated multi-turn absolute encoder that tracks revolutions without battery support. Frame designation 093 and length code A give the motor a compact form that suits space-limited machine layouts.

For mechanical integration, the flange carries a centering recess of 110 mm so it registers accurately against gearboxes or adapter plates. Power and feedback leads exit on side A through a connector, which allows direct cable attachment without hardwiring. Torque is transferred by a plain shaft, and a fitted shaft seal helps block coolant and dust from entering the bearing set. Standard dynamic balancing helps limit residual vibration during operation, while the housing helps protect the motor in typical industrial environments. This layout is suited to machine areas where the shaft end and cable connection are exposed to routine splash or airborne contaminants.
