Product Description:

The MDD041A-N-100-N2G-050PA1 is a synchronous servo unit produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers that supply controlled three-phase power from an inverter. The motor converts that power into high-speed shaft rotation for positioning tasks on compact packaging lines, small gantries, and laboratory automation platforms. Its operating role is suited to compact servo axes that require repeatable motion, short settling times, and stable closed-loop response.

At standstill the rotor can hold a continuous torque of 0.64 Nm, and when energized it can accelerate up to its nominal speed of 10000 rpm. This pairing supports rapid duty cycles during short indexing moves without excessive heating. A centering diameter of 50 mm aligns the housing precisely on machine plates, while standard dynamic balancing keeps vibration within allowable limits during high-speed rotation. Power and feedback conductors exit on side A through a molded connector, which helps keep external wiring straightforward in compact cabinets. Motion feedback is provided by resolver feedback, which supplies rotor position data to the drive for closed-loop control. The size code 041 and length code A identify the stator stack dimensions, and the housing uses the standard sealed variant for general plant environments.

A blocking brake integrated at the non-drive end can apply 1.2 Nm of holding torque to secure vertical loads when power is removed. The output interface uses a keyed keyway shaft for positive torque transmission to pulleys or couplings. The shaft is furnished with a shaft seal, so lubricant from adjacent gear stages cannot escape into the motor interior. A standard shaft end is used on the drive side, and resolver wiring shares the same connector shell. The shared connector arrangement keeps the package compact while preserving ingress protection around the connection area.
