Product Description:

The MDD093C-N-020-N2L-130GR1 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts drive current into controlled angular motion for positioning, indexing, and speed-regulated processes on automated machinery. The integrated blocking brake helps keep an axis in place when power is removed, and the plain shaft supports common coupling arrangements. The motor is suited to assembly lines, material-handling stations, and other equipment that requires repeatable rotary motion.

This motor uses a centering pilot of 130 mm, so the housing seats concentrically in a machine frame without additional shims. Its nominal speed rating is 2000 rpm, and the drive must supply the corresponding electrical frequency to reach that output speed. The blocking brake provides 11 Nm of torque, which helps resist back-driving from vertical or unbalanced loads when the motor is de-energized. Rotor position is returned to the controller through digital servo feedback (DSF), enabling closed-loop velocity and position correction. Power and feedback leads exit on the right side, which can simplify cable routing in cabinets that group drives along a common rail. A protective shaft seal is fitted at the output end to limit lubricant migration and the entry of airborne contaminants.

Electrical terminations are completed through a keyed connector, providing a secure interface for the motor leads. The stator stack follows size code 093, giving the motor a mid-frame format suited to many general automation axes. The length designation C indicates a longer active section than shorter lengths in the same frame, which supports higher continuous torque. Standard dynamic balancing helps reduce vibration at speed, and the lack of a side B shaft end keeps the assembly compact. This arrangement also reduces overhung mass on the far bearing and leaves more clearance behind the motor.
