Product Description:

The MDD090A-N-020-N2M-110PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts commanded current into controlled rotary motion for positioning and speed-regulated axes. The 090 frame and compact A length fit automated presses, gantries, and pick-and-place modules where installation space is limited. Standard housing construction and standard rotor balancing support stable running, and a single connector carries both power and signal connections while the motor uses only a side A shaft output, so no auxiliary shaft extends from side B.

Mechanical alignment uses a centering diameter of 110 mm, and all external wiring exits on the right side to simplify routing in multi-axis layouts with limited cable clearance. Under rated conditions, the rotor reaches 2000 rpm and provides a continuous standstill torque of 3.7 Nm, which supports steady holding force at low speed and during short pauses in a machine cycle. A blocking brake can hold up to 6.5 Nm when power is removed, which helps prevent vertical or overhung loads from drifting while the axis is stopped. This operating profile suits indexing tables, feed rolls, and similar axes that must start, stop, and hold position repeatedly.

Position data is supplied by an internal integrated multi-turn absolute encoder working with digital servo feedback for closed-loop control. This arrangement lets the controller track shaft position across multiple revolutions and maintain accurate motion after power-up, which is useful on axes that cannot tolerate reference loss. The output shaft uses a keyway for positive torque transfer, and the motor is supplied with a shaft seal to help limit splash and contaminant entry at the shaft end during routine machine operation.
