Product Description:

The MDD071C-N-030-N2S-095PB2 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is designed for use with digital drive controllers and converts electrical power from the drive into regulated mechanical rotation for positioning and velocity tasks in automated production cells, pick-and-place stations, and packaging machinery. Its synchronous design supports repeatable motion on axes that require controlled acceleration, deceleration, and steady speed under changing loads during frequent start-stop cycles in automated equipment.

The motor’s centering flange is machined to 95 mm, a diameter that ensures accurate alignment with gearboxes or mounting brackets so radial runout remains within tolerance. Power and feedback cabling exits on Side B, keeping connectors clear of moving machine elements in right-hand layouts. A single connector interface carries both phases and encoder lines, reducing wiring complexity. At standstill, the electromagnetic package delivers 6.6 Nm of continuous torque, allowing the axis to support process loads without exceeding its thermal limit. During motion, the rotor reaches a synchronous velocity of 3000 rpm, matching compatible drives used with this frame.

Position holding is provided by the integrated blocking brake, which applies 6.5 Nm when the controller issues a clamp command or when power is removed. Rotor position is reported through digital servo feedback, giving the drive fine-grained resolution for dynamic tuning while keeping the signal path resistant to noise. The shaft is ground with a keyway so pulleys or couplings can be locked without additional machining, and a shaft seal helps prevent lubricant migration into the stator cavity. Standard dynamic balancing, the C length code, and the 071 frame size help limit vibration inside the housing. The design also omits a rear shaft extension to reduce overhung mass.
