Product Description:

The MDD071B-N-N2T-095PA3 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is a motor for digital drive controllers, so it accepts commanded current from an inverter and delivers closed-loop motion for automated tooling, pick-and-place modules, and material-handling axes. This arrangement supports repeatable positioning and stable speed control in automated motion systems. Its synchronous design lets the drive regulate torque and speed with the fast response expected in servo applications.

At standstill the motor can deliver a continuous torque of 4.4 Nm, allowing stable holding or low-speed feed tasks without thermal overload. Rotor position is detected by an optical encoder that issues 2,097,152 inc/rev. This high count, combined with a feedback accuracy of ±0.5 angular min, supports fine interpolation for precise contouring. In addition to the incremental data, an absolute position value over 4096 mechanical revolutions is supplied to eliminate homing at power-up. The flange pilot diameter is 95 mm, matching standard mounting interfaces, and a center hole of M3 × 8 aids alignment during installation. Power enters on Side A of the housing, simplifying cable routing inside compact cabinets. Mechanical drive is transferred through a keyway output shaft, and there is no secondary shaft on Side B. The motor is built to frame size 071 with length code B and uses the standard housing configuration.

The motor has an IP65 enclosure that blocks dust ingress and low-pressure water jets, so the unit can be mounted directly on machinery without a separate enclosure. The 19 mm shaft is sealed, which helps prevent lubricant washout during washdown cleaning. Operation is specified up to 1000 m installation altitude, maintaining thermal balance in most factory settings. Position data is delivered through the DSF + MTG dual-system feedback, which combines digital servo feedback with multiturn gearing to preserve count integrity if power is lost. This feedback arrangement retains position information across shutdowns and supports immediate restart without a homing cycle.
