Product Description:

The MDD090C-N-040-N2L-110PA2 is an AC synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical input from the drive into precise rotary motion that can be commanded in speed, position, and torque loops within assembly lines, packaging machines, and other automated stations. Its construction suits applications that demand repeatable movement cycles. This operating principle allows the motor to respond accurately to changing load conditions during synchronized machine motion.

The motor has a nominal speed of 4000 min⁻¹, allowing the axis to match the fast update rates of modern CNC and PLC control loops. Under standstill conditions, the motor can deliver 10.4 Nm of continuous torque, providing static holding capability without overheating. A built-in blocking brake adds an extra layer of safety; when energized, it can resist up to 11.0 Nm of load, permitting vertical or suspended axes to remain fixed after power-off. Position feedback is supplied through Digital servo feedback, giving the drive high-resolution rotor data for tight regulation. Accurate mechanical referencing is supported by the 110 mm centering diameter, which mates with standardized mounting surfaces and helps control runout.

Power and feedback connectors are oriented on Side A, simplifying cable routing when the motor is mounted on narrow machine frames. A shaft seal is fitted to limit dust or coolant ingress, and the output shaft uses a keyway profile so torque transfer relies on a standard keyed hub. The motor has size code 090 and length code C, which indicate its stator and flange envelope together with its active stack depth. Standard balancing and housing construction help reduce vibration during continuous cycling. This layout also supports stable connector-based wiring in machines that require frequent starts, stops, and direction changes.
