Product Description:

The MDD090B-N-040-N2M-130GR0 is a synchronous servo motor from Bosch Rexroth Indramat’s MDD Synchronous Motors series. It is intended for use with digital drive controllers that require accurate positioning and stable velocity regulation. This motor suits packaging equipment, pick-and-place axes, and other automated machinery that needs compact, high-speed rotary motion.

This model provides a continuous standstill torque of 7.2 Nm, which lets the shaft hold load at zero speed without exceeding normal thermal limits. Under rated excitation, it reaches a nominal speed of 4000 min⁻¹ for fast indexing and repeatable cycle timing. A centering diameter of 130 mm supports accurate alignment with standard flange patterns. Position data is returned through digital servo feedback (DSF), giving the drive precise bidirectional information for closed-loop control.

Torque is transmitted through a plain shaft, allowing couplings or pulleys to be fitted without a keyed shaft end. An integrated multiturn absolute encoder retains position information across multiple revolutions, which reduces the need for homing after power is restored. The motor uses frame size 090 with length code B, a combination that supports mid-range inertia and useful peak torque. It is built with a shaft seal to help protect the front bearing from coolant spray and similar contaminants.

Power and feedback conductors exit on the right side of the housing, supporting orderly cable routing in compact machines. The motor operates without a blocking brake, so vertical axes require external holding when power is removed.
