Product Description:

The MDD071C-N-040-N2S-095PB2 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precisely regulated rotary motion for pick-and-place modules, compact machining spindles, and packaging stations. Frame size 071 with a standard housing provides useful thermal surface while maintaining a compact footprint for dynamic axes. When paired with a compatible amplifier, the motor supports tightly coordinated motion in CNC- or PLC-controlled machinery, including applications that require fast acceleration and accurate speed regulation.

The motor has a nominal speed of 4000 rpm, allowing the rotor to support high-cycle production rates. At standstill, the energized winding supplies 6.6 Nm of continuous torque, which helps maintain stable holding force without excessive heat buildup. Power and encoder leads exit on Side B and terminate in a circular Connector for direct cable attachment. Accurate machine alignment is supported by a flange centering diameter of 95 mm. Rotor position is measured through Digital servo feedback (DSF), giving the drive high-resolution signals for responsive current and velocity control. Rotor components are balanced to a standard grade to help keep vibration low across the speed range.

The integrated blocking brake delivers 6.5 Nm of static torque, helping prevent load drift during emergency stops or loss of power. Mechanical output is transmitted through a shaft with a keyway, and the front bearing is protected by a shaft seal that helps separate lubricants from contaminants. Length code C sets the stator stack and overall body depth, while the omission of a rear shaft end reduces overhung mass near the encoder. This layout helps the motor fit compact machine spaces and supports stable coupling to the driven mechanism.
