Product Description:

The MDD090A-N-020-N2L-110GR0 synchronous servo motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, providing controlled torque and speed to mid-range automation axes in material handling, printing, and assembly cells. In closed-loop systems, it converts commanded current into repeatable rotary motion for feed axes, transfer mechanisms, and other positioning tasks. The 090 frame size and compact A-length stator give the motor a short overall package that can be flange-mounted close to the load. This layout helps reduce coupler overhang while still supporting positioning duty.

At standstill, the rotor can deliver 3.7 Nm of continuous torque, which supports holding or indexing stations at low speed. At full field excitation, the shaft reaches a nominal speed of 2000 rpm, which suits typical 4-pole inverter outputs in packaging or feeder lines. Position data are returned through Digital servo feedback (DSF), allowing the controller to correct position within a single electrical revolution. A centering shoulder of 110 mm aligns the housing with the machine interface. The rotor uses standard balancing, which helps keep vibration within ISO limits when it is coupled directly to precision gearboxes.

Power and feedback cables exit on the machine's service side because the electrical connectors are oriented to the right side. A single plug-in connector interface simplifies cable routing and keeps the connection arrangement compact. A factory-installed shaft seal helps prevent lubricant migration along the plain shaft when the motor is coupled to oil-filled gear reducers. The sealing arrangement also helps keep particles out of the bearing chamber during operation. The motor is supplied without a blocking brake, so external clamping or drive-applied holding current is required when power is removed.
