Product Description:

The MDD090C-N-040-N2L-110GB0 is a synchronous servomotor manufactured by Bosch Rexroth Indramat for integration into the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the unit converts regulated three-phase power into precise rotary motion that positions machine axes, maintains programmed speeds, and executes closed-loop moves in automated assembly lines, processing cells, and similar motion systems. Its mechanical interface follows ISO mounting standards for straightforward installation in compatible machine assemblies.

Mechanical layout follows the 090 frame code, and the C length variant provides additional stator volume without altering the mounting interface. A centering diameter of 110 mm locates the motor concentrically on the machine flange, while standard class balancing limits residual vibration at high speed. Rated continuous torque at standstill reaches 10.4 Nm, enabling the axis to hold loads without motion until commanded. During operation, the rotor can sustain a nominal speed of 4000 rpm, which suits packaging and conveyor duties that demand short cycle times and steady response. Power and feedback conductors are routed on the rear because the electrical connections are arranged on side B, and the motor uses a factory-installed connector that preserves the sealing of the housing. The enclosure uses the standard design, so dimensions and cooling paths match other motors in the series.

Control accuracy is enhanced by the integrated Digital servo feedback (DSF) encoder, which transmits high-resolution position data to the drive for accurate speed and position control. Because the motor is supplied without a blocking brake, stationary holding torque must be provided by the controller or an external mechanism. The output shaft is a plain shaft with standard single-ended geometry, and no secondary shaft is present on the rear face. Contaminant ingress at the journal is limited by a shaft seal, allowing installation in environments where coolant spray or airborne particles are expected.
