Product Description:

The MDD071B-N-030-N2T-095GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current from an Indramat drive into rotary torque for positioning and speed control tasks in automated machinery. Position data are generated by an integrated multiturn absolute encoder and transmitted through the digital servo feedback channel for high-resolution closed-loop regulation during startup, low-speed running, and normal axis movement.

It supplies a continuous stall torque of 4.4 Nm, allowing the axis to support static process loads without motion. Under rated excitation, it reaches 3000 rpm; this nominal speed suits common inverter outputs and supports direct motor-to-load coupling where no extra reduction stage is needed. A mechanical holding brake provides 6.5 Nm of static torque for secure holding during power-off conditions. The rotor and flange are balanced to the manufacturer's standard grade, and the housing uses the standard enclosure form without added cooling fins. Electrical power, feedback, and brake lines exit on side B through a coded circular connector, which simplifies cable routing in compact cabinets and around neighboring machine components. Mounting is centered by a 95 mm locating shoulder that helps preserve concentricity, and the drive side keeps the standard single shaft end for straightforward coupling installation.

The motor belongs to size code 071 with length code B, giving it a compact body while maintaining the thermal capacity expected for this frame. A shaft seal helps prevent lubricant migration into the stator chamber and reduces the chance of contamination reaching the bearing area. The output journal uses a plain shaft so it can be connected to clamp or keyless couplings without secondary machining. This shaft arrangement also supports simple alignment in servo axes where low-backlash couplings are preferred for precise motion transfer.
