Product Description:

The MDD090C-N-020-N2L-130PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. In a drive system, it works with a digital controller and power stage to convert commanded current into rotary motion for machine tools, packaging stations, and material-handling axes. The motor is intended for closed-loop operation, so its mechanical interface and feedback hardware support accurate positioning, stable speed control, and repeatable response during frequent starts, stops, and reversals. That arrangement also supports smooth torque delivery at low speed and consistent motion through varying load conditions.

Mechanical output begins with a continuous standstill torque of 10.4 Nm, which indicates how much load the shaft can hold at zero speed while excitation is maintained. Under nominal electrical frequency, the rotor reaches 2000 rpm, giving the axis a practical base speed before gearing or controller tuning changes the final motion profile. Precise mounting is assisted by the 130 mm centering diameter, which helps align the flange with machine faces and reduces the chance of coupling misalignment. Position and velocity signals return through digital servo feedback, allowing the controller to monitor rotor movement continuously and correct deviations quickly. All power and encoder conductors exit on Side A of the housing, which helps keep cable routing organized in enclosed machines and reduces bending near the opposite end of the motor.

Cabling terminates on a sealed connector that supports secure attachment while helping maintain enclosure integrity at the connection point. The shaft uses a keyway profile for positive torque transmission to keyed hubs, and a shaft seal helps limit contaminant entry at the output end. Dynamic balancing is performed to standard balancing quality so normal operating vibration remains controlled in typical drive trains. The motor also uses a C-length stator stack and a size-090 frame with a standard single-ended shaft. It is supplied without an integrated holding brake, so any power-off holding function must be provided by the machine or drive system.
