MDD025B-N-100-N2G-040FC1
The MDD025B-N-100-N2G-040FC1 is a compact synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it serves as the prime mover on miniature feed axes and spindle modules where fast acceleration and accurate speed regulation are required in industrial automation cells. Its compact form also suits tightly packed machines where responsive motion and efficient use of space are important.
The motor reaches a nominal speed of 10,000 rpm, allowing high-cycle equipment to maintain throughput without gear multiplication. At standstill, it can supply 0.60 Nm of continuous torque, so closed-loop positioning remains stable with low heat rise. Electrical and feedback conductors exit on side A, which simplifies cable runs when the frame is mounted against a machine wall. Power is carried through a connecting cable with a coupling unit, which provides strain relief and quick disconnection. A centering diameter of 40 mm aligns the flange precisely, while the standard balancing grade limits vibration over the full speed range. The size-025 frame and length code B housing keep overall mass and inertia low for lightweight gripper or gantry installations.
Load retention during power loss is handled by an integrated brake that delivers 1.0 Nm of holding torque, allowing vertical axes to stop safely without external clamps. Rotor position is reported through resolver feedback, which supplies analog position signals and tolerates high temperatures and shock. Motion is transferred through a plain shaft that ships without a shaft seal, so separate splash guards are recommended in wet environments. A standard housing, a single-ended shaft, and the absence of a side B extension further shorten the assembly, permitting installation in densely packed multi-axis platforms.
