Product Description:

The MDD090C-N-040-N2M-110PB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts electrical energy into controlled mechanical rotation so that industrial axes can be positioned with repeatable accuracy in assembly, packaging, or material-handling equipment. The motor is intended for applications that require stable torque response and accurate axis movement under closed-loop control. Standard dynamic balancing minimizes vibration, and the 090 frame size with a standard housing helps the motor fit compact machine layouts.

This unit develops a continuous standstill torque of 10.4 Nm, allowing the driven load to be held without movement while energized. During normal operation, it reaches a nominal speed of 4000 rpm, matching fast cycle demands in pick-and-place gantries and other high-speed axes. A blocking brake rated at 11.0 Nm secures vertical loads when power is removed, which helps prevent unintended movement at rest. The centering flange has a diameter of 110 mm, providing a reference surface for precise housing alignment on the machine face. Power and feedback conductors exit on side B, and the electrical interface uses a keyed connector. This arrangement keeps the electrical connection grouped at one end of the motor and supports orderly cable routing in compact installations.

An integrated multi-turn absolute encoder works with digital servo feedback (DSF) to report position over multiple revolutions without homing. The feedback system supplies the drive with continuous rotor position data for closed-loop speed and position control. The shaft uses a keyway so couplings can be locked against slip during rapid acceleration or repeated reversing cycles. Motor length code C indicates the active stack depth used for this torque class. The motor has a single-ended shaft with no side B shaft extension, and a shaft seal is installed to limit the ingress of coolant or dust.
