MDD025C-N-100-N2G-040ME0
The MDD025C-N-100-N2G-040ME0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts commanded current into tightly regulated rotary motion for positioning tables, pick-and-place axes, and other automated assemblies. Its mechanical envelope and electrical design target installations that demand high spindle speed while maintaining precise torque control, allowing the controller to close velocity and position loops directly through the motor’s integrated feedback channel. The compact format also helps when the motor must fit beside tooling, guards, or other closely spaced machine components.
At standstill, the rotor can deliver a continuous torque of 0.90 Nm, so an axis can support moderate loads without external clamps. During operation, it reaches a rated speed of 10,000 rpm, enabling short machine cycles for small tooling or indexing disks. Mounting is guided by a 40 mm centering diameter that matches standard flange patterns, and the power and sensor leads exit on the left side, simplifying cable routing when the motor is recessed in a cabinet. Electrical hookup is performed through a connecting cable with a coupling unit, allowing quick exchange without opening the housing. The unit follows size code 025 and length code C, and it uses standard dynamic balancing with a standard housing for common brackets.
Position data is supplied by integrated resolver feedback. This lets the drive determine rotor angle during rapid acceleration and deceleration. The ground shaft uses a keyway to transmit torque into pulleys or miniature gearheads, and the standard shaft end is present only on the drive side to save space on the opposite face. The motor is delivered without a blocking brake, so holding force must come from drive torque or external mechanics when power is removed. It is also supplied without a shaft seal, so it should be mounted where low-pressure splash or oil ingress is not expected.
