Product Description:

The MDD090C-N-020-N2L-110PR1 synchronous servo motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts controlled current into repeatable rotary motion for indexing tables, handling axes, and other automation points. The housing follows the series' standard outline, the motor length code is C, and the shaft end is supplied in the standard single-ended form for direct coupling to machinery. In automated equipment, this repeatable motion helps axes start, stop, and hold commanded movement with consistent response from cycle to cycle.

A centering diameter of 110 mm aligns the flange to machine plates so runout is kept low during installation. This mounting feature helps the motor seat accurately against mating surfaces and supports stable shaft alignment. When held motionless, the windings can deliver 10.4 Nm of continuous standstill torque, which helps the motor sustain load without rotation. During regular cycles, the rotor reaches a nominal speed of 2000 rpm, making it suitable for medium-speed process axes. A fitted blocking brake provides 6.5 Nm of brake torque when power is removed, and digital servo feedback (DSF) supplies position data so the drive can maintain closed-loop speed and position control.

Power and signal cables exit on the right side, and a single connector plug carries the electrical connection. That arrangement supports orderly cable routing where access is limited on one side of the machine. Rotor mass distribution meets the balancing standard, helping reduce vibration when the 090 frame accelerates or decelerates. A shaft seal helps block dust and lubricants, while torque is transmitted through a keyway machined into the shaft. The standard housing removes heat by natural convection, so the motor can operate without an external fan.
