MDD041B-N-100-N2K-050FA0
The MDD041B-N-100-N2K-050FA0 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. This compact AC servo motor is intended for use with digital drive controllers, where it delivers precise torque and speed regulation for automated handling, packaging, and positioning axes. Its size 041 frame and B-length housing make it suitable for tight mechanical envelopes. The motor is well suited to axes that require repeatable starts, stops, and steady speed control during continuous machine cycles. Its compact form also helps when the motor must be mounted close to guides, tooling, or guarding on densely packed equipment.
The motor’s mechanical data describe how it mounts to the machine structure and how it behaves under load. The centering pilot is 50 mm in diameter, providing repeatable alignment on motor flanges. Under continuous stall conditions, it can supply 1.35 Nm of torque, allowing stable force production in static clamping or low-speed feed tasks. A maximum rated speed of 10000 rpm supports rapid indexing where high surface velocity is required. Rotor balance is provided in a standard grade, keeping vibration within limits for high-speed service. Closed-loop position control is aided by resolver feedback, which supplies rotor position information to the drive. This combination supports responsive motion on short-stroke axes that alternate between holding force and rapid travel.
Other features affect installation and electrical connection. An integrated absolute encoder supports position reporting for the drive, while the stainless-steel plain shaft avoids keyway stress points and is supplied without a secondary shaft end on side B to shorten overall length. Because the motor is supplied without a shaft seal, installations exposed to oil mist or washdown require an external sealing element. Power and feedback terminations are routed on side A through a single connector, which helps keep cable routing compact. Side A cable routing can also keep harnesses clear of couplings and other moving machine parts. This layout can reduce cable bending near the housing and leave more clearance around the rear of the motor.
