Product Description:

The MDD071B-N-040-N2T-095GB1 synchronous servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated DC-bus energy into rotary motion for positioning tasks in automated machinery. The design uses standard housing and balancing features, and its connector-based power and feedback terminals support straightforward installation without custom cable preparation. Used with digital servo feedback, the device provides closed-loop speed and position control inside multi-axis systems. This arrangement suits coordinated motion in packaging equipment, transfer units, and other automated axes that require repeatable response.

At zero speed the motor can deliver a continuous torque of 4.4 Nm, so it can maintain load during dwell phases without overheating. Once commanded, the rotor reaches a nominal velocity of 4000 rpm, which suits many medium-inertia feed axes. Mechanical alignment in the machine frame is aided by the 95 mm centering diameter, while all electrical connections exit on Side B, helping keep cabling away from couplers or transmission components on the drive end. An integrated multiturn absolute encoder supplies position data, and its signals pass through a factory-installed connector that also carries the DSF feedback stream. The motor length code is B, giving a mid-range stack height that balances torque density with weight. This feedback arrangement supports accurate position tracking during startup and stable control under changing load conditions.

Static holding requirements are handled by a blocking brake that maintains 3.0 Nm of restraint when power is removed, which helps prevent load drift on vertical axes. Frame designation 071 corresponds to the motor diameter and keeps inertia moderate for dynamic starts. Power is transmitted through a plain shaft protected by a shaft seal, helping keep lubricants inside and contaminants out in splash-prone areas. Because the shaft is present only on the drive side, the side-B shaft end is omitted, which leaves more room for cable routing in compact machine layouts. This layout can also help when the motor is mounted close to guards, panels, or adjacent machine structures.
