Product Description:

The MDD041B-N-100-N2K-050PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated current into precise rotary motion for positioning axes, pick-and-place units, and spindle drives in automated equipment. This operating role supports controlled acceleration, repeatable stopping, and stable speed regulation in compact machine axes. A centering diameter of 50 mm helps align the motor with the mounting flange and supports accurate shaft positioning during installation.

This model supplies a continuous standstill torque of 1.35 Nm, so the shaft can hold a load at zero speed without exceeding its thermal limit. During motion, it reaches a nominal speed of 10000 rpm, which supports high-rate indexing where short cycle times matter. The built-in blocking brake provides a holding torque of 1.2 Nm when power is removed, helping keep light vertical loads in place. Mechanical dimensions follow size code 041, giving the motor a compact footprint for multi-axis assemblies. A keyway shaft transfers torque through a positive mechanical connection, while the shaft seal helps limit lubricant migration and the single-ended shaft layout leaves the opposite end free of extra couplings. The plug-in connector also helps simplify cable routing in tight machine spaces.

The motor uses standard balancing to limit vibration during high-speed operation and reduce unnecessary mechanical stress on adjacent components. Power and feedback connections exit on side A, so both cable sets can be routed from the same end of the motor. Position data is provided by an integrated absolute encoder, which allows the drive to detect shaft position immediately after startup and maintain accurate commutation during operation. The motor has length code B, and the housing uses the standard enclosure for this frame size.
