MDD025B-N-100-N2G-040FE1
The MDD025B-N-100-N2G-040FE1 is a brushless synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts regulated electrical power into precise rotary motion for light-duty positioning stages, pick-and-place heads, and compact gantry axes in automated assembly lines. The compact package suits semiconductor handling tools, labeling modules, and other equipment that requires rapid, repeatable movement. Its small size also makes it useful in machines where moving mass and installation space must be kept low. This type of motor is well suited to short-travel automation axes that need quick acceleration and accurate repeatability without a large mechanical envelope.
During operation, the rotor can reach a rated speed of 10000 rpm. Continuous stall torque is 0.60 Nm, allowing small loads to be held at standstill while current is maintained. A blocking brake provides 1.0 Nm of holding torque to prevent drift when the drive is de-energized. Position and speed are measured through resolver feedback, whose analog signals support stable closed-loop control across the speed range. Accurate axial registration is supported by a flange pilot of 40 mm, which helps keep the motor centered on the mating machine surface and reduces radial runout.
Power and feedback connections exit on the housing's service side, and the designated connection direction is Left. The preassembled connecting cable with coupling unit simplifies installation in compact machine sections where cable routing space is limited. Torque is transmitted through a plain shaft, which omits keys and supports space-saving couplings. The rotor uses a standard balance grade to help limit bearing loads during high-speed operation. Frame size 025 keeps the outer dimensions compact, and the motor does not include a shaft seal, so it should be installed away from coolant spray or oil mist.
