Product Description:

The MDD093A-N-040-N2M-110GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Built for digital drive controllers, it supplies tightly regulated rotary motion to positioning, packaging, and tooling axes in automated plants. A standard housing shields the windings from airborne debris, and standard dynamic balancing helps keep vibration low when the rotor is coupled to pulleys or gearsets. The synchronous design supports accurate speed regulation and repeatable positioning during indexing, contouring, and rapid start-stop cycles. It can be used where precise synchronization between commanded motion and actual shaft position is required.

Mechanical interface accuracy is provided by a 110 mm centering diameter that aligns the flange with minimal runout. The motor uses frame code 093 and the short A length code, which helps conserve installation space. The short housing can be useful where adjacent machine elements limit axial clearance. Under rated cooling, it delivers 9.2 Nm of continuous standstill torque, allowing the drive to maintain force at zero speed during controlled holding. During motion it reaches a nominal speed of 4000 rpm, supporting fast linear stages and small spindles. Power is transmitted through a plain shaft, while the opposite end remains blank for compact machine layouts.

All electrical terminations exit on the Side B face through a molded connector, easing cable routing in multi-axis enclosures. Position data comes from an integrated multiturn absolute encoder, and the drive uses that signal for digital servo feedback and closed-loop commutation. A factory-installed shaft seal helps block lubricant migration along the shaft and reduces the chance of contaminants reaching the bearing area. Because the motor is supplied without a blocking brake, an external holding method is required when the axis must remain fixed during power loss. The absolute feedback system also allows position data to be available immediately after startup without relying on a separate homing cycle.
