MDD071B-N-060-N2T-095GL2
The MDD071B-N-060-N2T-095GL2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. This motor is intended for use with digital drive controllers where precise position and velocity loops are needed for automated handling, packaging, or machine-tool axes. As a compact 071-frame unit, it supplies continuous torque for moderate loads, and the integrated multi-turn absolute encoder sends rotor position data directly to the drive for closed-loop operation. This arrangement allows the control system to monitor shaft position immediately after startup and maintain stable motion during repeated indexing cycles.
Its centering diameter measures 95 mm, allowing the flange to seat accurately on a gearbox or mounting plate and helping reduce radial runout. A rated mechanical speed of 6000 rpm is suitable for fast traverse moves and high cycle rates. Continuous torque at standstill is 4.4 Nm, so the motor can hold a load when energized. Power and feedback conductors exit on the left side, and the housing uses a plug-in connector for straightforward cabling. The compact connection layout also helps where machine clearances are limited. Standard dynamic balancing and the B length code keep vibration behavior and overall mass within the normal range for this frame size.
A blocking brake is installed and supplies 6.5 Nm of static torque, securing vertical or overhung axes during power loss. Position data reaches the controller through digital servo feedback (DSF), which supports accurate speed and position control inside the drive. Motion is transmitted by a plain shaft protected by a shaft seal that helps limit lubricant escape and contaminant entry. The sealed shaft end supports use in machines where dust or splash can reach the drive end, and the integrated encoder removes the need for a separate external feedback device.
