Product Description:

The MDD090B-N-040-N2M-110GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it transforms phase-controlled current into precisely regulated shaft motion in automated machinery. The motor suits indexing tables, transfer units, and medium-inertia axes that require quick acceleration, stable velocity control, and reliable holding performance.

Its continuous standstill torque reaches 7.2 Nm, so the rotor can hold load at zero speed without exceeding normal thermal limits. A nominal speed of 4000 min⁻¹ provides a practical operating point for velocity loops and supports direct coupling or moderate gear reduction. During emergency stops or power loss, the blocking brake delivers 11.0 Nm to restrain motion and help secure vertical or suspended axes.

Position information is supplied by an integrated multiturn absolute encoder, which lets the controller recover axis location after shutdown without a homing cycle. A centering pilot of 110 mm helps align the flange on the machine interface, while digital servo feedback transmits high-resolution signals to the drive. The motor uses a plain shaft for clamp-style couplings and includes a shaft seal to limit dust and fluid ingress during operation. This combination supports accurate commutation, predictable coupling behavior, and cleaner operation where airborne debris or occasional fluid spray could otherwise shorten component life prematurely.
