Product Description:

The MDD090A-N-040-N2L-130PB2 is a permanent-magnet synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Its A-length construction and 090 frame size place it within a compact motor class used for precise industrial motion tasks. Designed for use with digital drive controllers, it converts electrical commands into controlled rotary motion for pick-and-place axes, packaging spindles, and general positioning stages. The permanent-magnet rotor supports quick response to command changes, which is useful where repeatable acceleration and stable speed control are required throughout frequent operating cycles.

A centering diameter of 130 mm allows repeatable alignment to gearboxes or machine frames during installation. When energized, the stator can generate a continuous standstill torque of 3.7 Nm, which indicates the load it can support continuously without exceeding thermal limits. The rotor reaches a nominal speed of 4000 rpm, giving the paired drive a broad operating range before field weakening is needed. Power and feedback leads exit on side B, and a detachable connector simplifies cable installation by avoiding hard-wired terminations. This cable layout can also reduce tight bends near the housing and keep the mounting face clear for direct attachment.

An integrated blocking brake provides 11.0 Nm of static torque to hold vertical loads when the drive is disabled. Position data is supplied through Digital servo feedback, enabling closed-loop control without an external encoder. Torque is transferred through a shaft with a keyway, and the front end is fitted with a shaft seal to help limit contamination at the bearing area. The standard housing supports use in typical machine assemblies, and the compact body helps conserve installation space where medium-inertia axes cycle repeatedly under moderate torque demand.
