MDD041B-N-100-N2K-050PB1
The MDD041B-N-100-N2K-050PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified for use with digital drive controllers, it converts commanded current into precise shaft motion for positioning, feed, and spindle axes in automated equipment. An integrated absolute encoder reports rotor position immediately after power-up, so the axis can begin operation without a reference move. This supports short startup sequences in machines that must resume production quickly after a stop. Standard housing and balancing support installation in equipment that requires high rotational speed, stable running, and repeatable motion.
The motor’s nominal running speed is 10000 rpm, which is the rated continuous speed for normal operation. At standstill, it can provide 1.35 Nm of torque, supporting controlled holding force during low-speed motion or brief dwell periods. Accurate alignment is established by a 50 mm centering diameter, and all electrical connections exit on Side B to keep cables away from driven components. The 041 frame size gives the motor a compact stator diameter for installations with limited space. Standard dynamic balancing helps reduce vibration across the speed range, and the sealed housing helps protect internal windings from dust and airborne coolant.
A factory-installed blocking brake provides 1.2 Nm of static torque to hold the shaft when power is removed. Motion feedback is supplied through resolver feedback, which provides analog sinusoidal signals for commutation and speed control during operation. A molded connector simplifies electrical hookup, and an axial shaft seal helps keep debris and lubricant away from the bearing chamber. The motor uses a keyway shaft for positive torque transfer to couplings or pulleys. It also has length code B in a single-ended design, leaving the opposite side free of a second shaft extension.
