Product Description:

The MDD093A-N-020-N2L-130GB0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current from an inverter into rotational motion for axes that require position-controlled operation. Its compact A-length construction and size 093 frame allow integration inside multi-axis machines where space and inertia are limited. Standard balancing keeps vibration low during continuous duty. Because it is intended for use with digital controllers, the motor supports responsive torque changes during acceleration, deceleration, and short positioning moves.

Its continuous stall capability of 9.2 Nm is the torque available when the rotor is energized but locked, which is useful when evaluating holding loads under closed-loop control. During motion, the shaft can reach a nominal speed of 2000 rpm, aligning the mechanical output with the drive command range. Accurate commutation is derived from the integrated digital servo feedback, which reports position and velocity to the controller for stable speed regulation and precise reversal. The feedback signals also allow the controller to correct small speed deviations caused by changing load conditions. Mounting is centered by a 130 mm pilot diameter that aligns the motor to the machine housing with minimal runout. Power is transmitted through a plain shaft, which reduces stress concentrations at the coupling interface by omitting a keyway.

Electrical and signal terminations are directed toward the rear because the cabling exits on Side B, and a sealed connector pair carries both power and transducer lines. This arrangement helps keep cables clear of couplings, belts, or other moving parts near the drive end. Rear-facing connections can also reduce cable bend near the mounting face in densely packed machine frames. The motor is supplied without a holding brake, so external load-securing methods are required if the axis must remain fixed after power is removed. A standard housing with an IP-rated shaft seal helps protect internal components from lubricant splash and routine shop contamination. The closed non-drive end supports use in compact enclosures where exposed rotating parts at the rear are undesirable.
