Product Description:

The MDD071C-N-040-N2L-095GB0 is an AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into controlled rotary motion for positioning, indexing, and process-rate regulation in automated machinery. The model works with compatible Indramat drive modules to provide closed-loop torque and speed control in packaging equipment, printing lines, and general-purpose assembly stations. This makes it suitable for axes that require repeatable starts, stops, and speed changes during normal operation.

The motor uses a centering diameter of 95 mm to align the stator housing on the machine frame. Power and feedback cables exit on Side B, and they terminate through a single connector that simplifies wiring. Under continuous stall conditions, the motor supplies 6.6 Nm of torque for stable static positioning without overheating. It can accelerate loads up to its rated speed of 4000 rpm when used with a compatible inverter. The housing is the standard version, and the motor is supplied without a blocking brake, so the shaft must be held by external hardware or drive-applied torque during power-off conditions.

Performance consistency is supported by the motor’s digital servo feedback (DSF) system, which transmits high-resolution rotor position data to the drive so commanded profiles stay synchronized with mechanical output. The unit uses frame size 071 with C length, which provides a longer active motor section without increasing the outside diameter. This arrangement helps raise torque density while keeping the motor compact. The drive end uses a plain shaft, and a shaft seal surrounds the shaft to help prevent lubricant migration into the encoder chamber. That layout helps protect the feedback area during repeated motion cycles.
