Product Description:

The MDD025C-N-100-N2K-040GD0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. As a compact synchronous motor for digital drive controllers, it supplies rotational power to axes that need tight velocity and position regulation inside packaging stations, small pick-and-place gantries, and diagnostic devices. The series’ magnetic design allows this C-length, size 025 frame to deliver repeatable torque at high speed while remaining compatible with the manufacturer’s existing drive firmware and cabling practices.

The motor reaches a rated speed of 10000 min⁻¹, enabling fast indexing cycles when coupled to low-ratio gearboxes or direct-drive ballscrews. Its continuous standstill torque of 0.90 Nm defines the sustained load it can hold without excess heating. A centering diameter of 40 mm aligns the flange precisely with servo mounts, limiting radial runout that can influence encoder accuracy. Power and feedback conductors exit on Side B; this orientation simplifies wiring when the motor is placed deep in a machine frame. The factory-installed connecting cable with coupling unit provides strain relief and correct pin assignment for quick swap-out. Position data comes from an integrated absolute encoder, so homing routines are unnecessary after power restoration, and multiturn information can be passed directly to the drive for process resumption.

Several mechanical features underpin those performance figures. Operation is balanced to the Standard grade, reducing vibration at speed even though the unit is supplied without a blocking brake; systems that require static holding torque must rely on the drive’s servo-lock or external clamps. Feedback redundancy is possible because the rotor also carries resolver feedback tracks that some controllers can access for diagnostic comparison. A plain shaft with a fitted shaft seal keeps lubricants in the bearing cavity and prevents fine contaminants from reaching the encoder chamber, supporting long service intervals despite the high rotational speed profile.
