Product Description:

The MDD093A-N-020-N2M-110PR1 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Classified as a motor for digital drive controllers, it supplies rotary motion to automation axes that rely on closed-loop speed and torque control. The unit is built in the 093 frame size with a standard housing and standard dynamic balancing, allowing direct installation in machinery without additional vibration tuning. Its synchronous design supports repeatable motion in feed axes, handling systems, and other equipment that depend on stable servo response.

The motor can supply a continuous standstill torque of 9.2 Nm, so it can hold loads without exceeding its thermal limit while stationary. Under normal duty, the rotor reaches a nominal speed of 2000 rpm, which the connected drive uses for velocity scaling. A centering diameter of 110 mm aligns the stator flange precisely with mounting pilots on machine plates, gearboxes, or brackets. All power, feedback, and brake leads exit on the right side through a sealed connector, helping simplify cable routing inside the machine. The motor length code A indicates the shortest stack in the 093 family and helps keep inertia low. Standard housing and keyway shaft geometry allow direct connection to pulleys or couplings, while the shaft end is provided only on side A to avoid overhung loads on the rear bearing.

For position retention, a blocking brake supplies 11 Nm of static torque and engages automatically when power is removed. Position data is captured by the integrated multiturn absolute encoder, so the controller can retain rotor angle information after power cycles. Feedback is transferred over DSF, giving the drive high-resolution speed and position signals for tight control loops. A durable shaft seal keeps lubricants inside the bearing chamber and helps prevent contaminants from entering in areas where oil mist or dust is present.
