MDD065C-N-040-N2M-095PR1
The MDD065C-N-040-N2M-095PR1 is a synchronous servo motor developed by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts controlled electrical power into rotational motion for positioning, speed, and torque tasks in automated machinery. The unit integrates with Rexroth drives for closed-loop operation in packaging lines, printing cylinders, and handling axes. By embedding feedback inside the frame, the motor supports compact cabinet layouts in multi-axis systems.
It is designed for a nominal speed of 4000 rpm, allowing high cycle throughput while maintaining synchronous accuracy with the inverter output frequency. At standstill, the electromagnetic system can sustain 2.1 Nm of continuous torque without exceeding thermal limits, so small payloads can be held steadily during dwell periods. A blocking brake is installed, and its mechanical clamp delivers 3.0 Nm of static holding torque to secure the shaft when power is removed or during emergency stops. Position information is generated by an integrated multi-turn absolute encoder, enabling homing-free startups and retaining revolution data after shutdown. Velocity and torque loops use Digital servo feedback (DSF), which sends high-resolution data to the drive for responsive control.
A centering diameter of 95 mm aligns the flange with standard Rexroth mounting surfaces and helps keep radial runout low. Power and feedback conductors exit on the right side through a sealed connector, which helps simplify cable routing when multiple motors are mounted on a common plate. The rotor uses standard balancing, so additional field balancing is not required. The motor uses a keyway shaft and a shaft seal, which helps prevent slip under torque load and limits lubricant ingress in areas with coolant mist or light dust.
