MDD025C-N-100-N2G-040FA1
The MDD025C-N-100-N2G-040FA1 is a synchronous AC motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit converts commanded current into mechanical rotation for compact feed axes, pick-and-place heads, and high-speed spindles in automated equipment. Its small frame combines the motor, brake, and feedback system in one assembly, which helps reduce external wiring and keeps multi-axis machine layouts compact where precise motion and limited panel space are important.
Its nominal shaft speed reaches 10000 rpm, helping shorten cycle times when it is paired with lightweight tooling. Under continuous stall conditions, the magnetic circuit supplies 0.90 Nm, allowing the axis to resist process forces without overheating during sustained low-speed operation. The blocking brake clamps up to 1.0 Nm after power is removed so vertical or suspended loads remain stationary. Mounting accuracy is supported by the 40 mm centering diameter, and dynamic imbalance is limited to the standard balancing grade to help reduce vibration at high speed. Cabling exits on side A through a circular connector, which keeps the opposite face clear for nearby hardware and simplifies routing in tight installations.
Position information is generated by resolver feedback, and the analog sine-cosine signals remain stable in the presence of electrical noise from switching inverters. The motor is supplied with a plain shaft, and because it does not have a shaft seal, the coupling area should be protected from fluid ingress. The enclosure uses motor length code C within the motor size 025 frame, which keeps rotor inertia low and supports the motor’s high-speed operating range. The housing and shaft end follow the standard series pattern, allowing the unit to fit machine layouts built around this compact frame format.
