Product Description:

The MDD041B-N-100-N2K-050MB1 is a servo motor produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit converts commanded current into mechanical rotation in compact positioning axes, pick-and-place heads, and other automated machinery. It delivers high-speed motion while maintaining small frame dimensions, which makes it suitable for tightly packed multi-axis systems on assembly lines and test rigs. Its compact format is useful where several motors must be installed close together without sacrificing access to neighboring slides, sensors, or tooling. For general-purpose installations, it uses standard rotor balancing and a housing format that fits modular mounting hardware.

The mechanical interface includes a centering diameter of 50 mm, which aligns the motor on the machine plate and helps control radial runout. Power and feedback cabling leave the stator on side B through a sealed connector, allowing straight routing toward the cabinet and keeping the working side of the axis less obstructed. Under continuous stall conditions, the electromagnetic package supplies 1.35 Nm of torque, which supports fine indexing and holding tasks at low speed. During normal operation, the rotor can reach 10000 rpm, supporting short cycle times in applications with light inertia and short travel distances. This combination supports compact mechanical layouts that still need accurate alignment at the mounting face and predictable torque at standstill.

Static holding is supported by an internal brake rated at 1.2 Nm, so vertical axes can remain immobilized when power is removed. Position feedback comes from an integrated absolute encoder, and the drive can also use built-in resolver feedback for speed-related control functions during operation. That arrangement gives the control system immediate position information after startup and stable feedback during repeated acceleration and deceleration. The shaft uses a keyway to transfer torque to pulleys or couplings without slip, and the lack of a shaft seal reduces drag in high-speed duty. Because there is no shaft seal, the motor is better suited to clean, dry environments where contamination at the shaft opening is limited.
