Product Description:

The MDD071B-N-N2T-095PA5 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it turns commanded current into precise rotary motion for machine tools, pick-and-place modules, and other automated axes that require accurate velocity and position control. Its synchronous design supports responsive acceleration and stable speed regulation during repeated start-stop cycles. It is well suited for closed-loop motion systems where changing loads still require repeatable positioning during operation.

At rest, the motor can supply a continuous holding torque of 4.4 Nm, allowing stable load support without thermal overload. A centering diameter of 95 mm locates the stator concentrically against mounting interfaces and helps minimize runout during installation. Position feedback is gathered through an optical system that resolves 2,097,152 inc/rev and stores multi-turn data across an absolute span of 4096 motor rev, so the drive retains shaft orientation after power loss. Enclosure sealing rated to IP 65 protects the windings and encoder from dust and water jets, allowing the unit to operate on exposed machine frames. The digital servo feedback with multi-turn absolute coding connects directly to compatible drive amplifiers for high-speed closed-loop regulation.

Mechanical balance class R reduces residual vibration, and the keyed shaft follows a 6 × 6 × 32 mm geometry for torque transfer through standard couplings. Within motor size 071 and length code B, the assembly remains compact while delivering rated dynamics. Installation is permitted up to 1000 m elevation without derating, and the housing dissipates heat through natural convection. Power cables enter from Side A, which can help routing in machines where the drive connection is mounted on the same side. The keyed output shaft also supports straightforward attachment to pulleys, couplings, or gears.
