MDD025B-N-100-N2G-040FE0
The MDD025B-N-100-N2G-040FE0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated current from the drive into mechanical rotation for positioning or velocity-controlled axes in industrial automation. Its standard housing and standard balancing support installation in compact machinery without special mounting changes, and the shaft end remains in its standard form with no extension on side B. This layout makes the motor suitable for tightly packed assemblies where consistent alignment and compact dimensions are important.
This model delivers a continuous standstill torque of 0.60 Nm, enabling small actuators to hold load without overheating during normal operation. During operation, it can reach a nominal speed of 10,000 rpm, which suits high-throughput packaging or pick-and-place stations that rely on short cycle times. The motor seats into fixtures by a centering diameter of 40 mm, helping maintain alignment between the rotor and the driven mechanical elements. Electrical and feedback leads exit on the left side, so the cable path remains fixed during machine layout. A plain shaft eliminates keyways, reducing stress concentrations and supporting couplings that clamp directly onto the cylindrical surface. There is no shaft seal, so the installation area should remain free of liquid splash.
Power reaches the stator through a connecting cable with a coupling unit, which simplifies disconnection when the motor must be removed from the machine. Position and speed are reported by resolver feedback, which provides analog sinusoidal signals that many Bosch Rexroth drives can read without additional converters. The motor is supplied without a blocking brake, so static holding torque must come from the drive or from external mechanical restraint. The motor uses size code 025 with length code B, giving a compact frame with enough active material for the listed torque while keeping overall mass low. This combination suits compact axes that need fast response and stable servo control without adding unnecessary mechanical complexity.
