Product Description:

The MDD090C-N-040-N2M-110PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, it converts regulated stator current into mechanical rotation for automated axes that require precise speed and position control. The 090 frame with a C-length stack gives the motor moderate inertia, which suits indexing tables, pick-and-place gantries, and coil-winding equipment where repeatable starts and stops are common. Its synchronous design allows the paired controller to maintain commanded motion profiles during both continuous running and short positioning moves. A standard keyed shaft end on the drive side transmits torque to the driven machine, while the lack of a secondary shaft on side B helps the motor fit into tight machine spaces.

It delivers a continuous standstill torque of 10.4 Nm, allowing the drive to hold load forces without overheating when motion is paused. During operation, the rotor reaches a nominal speed of 4000 rpm, supporting rapid acceleration cycles in high-throughput cells. Accurate mechanical alignment is facilitated by a 110 mm centering diameter that mates with precision locating pockets, and standard dynamic balancing keeps vibration within limits at that speed. The motor uses frame size 090 and length code C, which give it an extended lamination stack for higher continuous torque without changing the mounting interface. That operating range is useful in machines that alternate between dwell periods and fast transfer moves.

Electrical and feedback interfaces are routed on Side A, and the power leads terminate in a sealed connector that matches the designated connection type. Position data comes from an integrated multiturn absolute encoder, while phase current is regulated through digital servo feedback channels inside the controller for stable closed-loop operation. Because the encoder is absolute, the controller can retain position information across multiple revolutions. The output shaft is protected with a shaft seal, which helps protect the bearing area from contamination during normal machine use. The motor is supplied without a blocking brake, so external holding methods must secure static loads when power is removed.
