Product Description:

The MDD093A-N-040-N2M-130PA0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it forms the electromechanical link between inverter output and machine motion, converting commanded electrical values into controlled rotary movement. In automated equipment, this allows conveyor sections, tool changers, pick-and-place heads, and similar axes to index, position, and follow speed commands with high accuracy. The motor is intended for closed-loop operation, where the drive continuously compares commanded motion with actual rotor position and corrects deviations during acceleration, deceleration, and load changes.

Rated for a nominal velocity of 4000 rpm, the unit can follow rapid speed commands across a wide operating range. At standstill it provides 9.2 Nm of continuous torque, which supports stable holding force when the drive remains energized. A centering shoulder of 130 mm helps align the motor on the mounting flange, and the power and feedback leads exit on Side A through a sealed connector for straightforward cable routing. The drive receives rotor position information through digital servo feedback, allowing accurate speed regulation and positioning. The 093 frame with the compact A length keeps the motor suitable for installations where axial space is limited and moving mass should remain low.

An integrated multiturn absolute encoder is mounted in the rear housing to provide absolute position data and revolution tracking to the controller immediately after power-up. The output shaft uses a keyway for positive torque transmission and includes a shaft seal to help limit lubricant migration and contaminant entry at the shaft opening. The motor uses a single-ended shaft arrangement with no extension on side B, which reduces the space required behind the machine interface. Because it is supplied without a blocking brake, any load that must remain fixed with power removed requires external holding force. Standard housing execution and normal balancing support smooth operation during repeated motion cycles.
