Product Description:

The MDD093C-N-040-N2M-130GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into controlled rotary motion for packaging lines, handling robots, and machine-tool spindles. By combining permanent-magnet excitation with closed-loop feedback, the motor supports repeatable torque delivery and accurate position control during frequent speed changes. This arrangement helps coordinated axes maintain consistent motion even when process loads change during operation.

Its nominal speed is 4000 rpm, allowing high cycle rates in applications that require rapid acceleration and deceleration. The centering diameter of 130 mm positions the motor accurately against the machine register to help reduce coupling misalignment. Position information is provided by an integrated multiturn absolute encoder, so the axis can retain position data after power is removed. That encoder communicates through digital servo feedback (DSF), supplying the controller with precise signals for current, velocity, and position control. For load holding during shutdown, the blocking brake provides 22 Nm of static torque.

Power and feedback terminations are located on the motor’s right side, which can simplify cable routing when the axis layout requires the harness to follow a specific direction. A sealed circular connector provides the electrical interface to the drive cabinet and helps maintain shielding continuity across the cable assembly. The rotor uses a plain shaft, and the integral shaft seal helps protect the bearing cavity from coolant spray while reducing the chance of lubricant loss. The motor also uses standard balancing, which helps keep vibration within normal limits when the unit operates at rated speed.
