Product Description:

Bosch Rexroth Indramat builds the MDD071B-N-030-N2S-095PR1 as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical power into precisely regulated mechanical rotation inside packaging lines, handling robots, printing modules, and similar automated equipment. Permanent-magnet excitation, a compact stator, and electronic feedback let the unit deliver repeatable torque and position control, making it suitable for synchronized indexing, contouring, and other coordinated multi-axis motion in industrial automation.

At stall, the motor sustains 4.4 Nm of continuous torque, enabling static load holding without overheating during closed-loop positioning tasks. Under rated excitation, it reaches a nominal speed of 3000 rpm, supplying the surface velocities common to mid-range gantry systems. For vertical axes, a built-in blocking brake applies 3.0 Nm of holding torque so the axis remains fixed when the inverter is disabled. Commutation accuracy is maintained through digital servo feedback (DSF), which transmits absolute rotor position to the controller on every cycle. Mechanical centering on machine plates is provided by a 95 mm pilot diameter. The B length keeps inertia moderate while preserving thermal capacity.

Operational smoothness comes from standard balancing, which limits residual shaft vibration across the full speed range. Cabling exits on the right, simplifying harness layout in cabinets, and a multi-pin connector supports secure cable attachment. The motor is housed in a standard enclosure protected by a shaft seal that blocks spray and dust from reaching the bearings. The 071 size code indicates the outer stator diameter, while a keyway shaft profile transfers torque to couplings without slip. The shaft is present only on side A, which reduces rear overhang and helps the motor fit into compact machine spaces.
