MDD041B-N-100-N2K-050MB0
The MDD041B-N-100-N2K-050MB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts regulated current from an inverter into rotational motion that can be closed-loop controlled by the host CNC or PLC. The unit uses a standard aluminum housing that dissipates heat by natural convection. Because cooling is passive, the motor can be integrated where external fans or liquid lines are not desired. Its compact format suits axes where high spindle speed is needed in packaging, pick-and-place, or small machining centers.
The motor’s nominal speed reaches 10,000 rpm, so the drive can supply high surface velocity with limited gear reduction. At standstill it delivers 1.35 Nm of continuous torque, which supports steady holding force for tensioning, indexing, or vertical loads. Position data originate from an integrated absolute encoder, which reports multi-turn rotor angle to the controller at power-up and eliminates homing routines. For better immunity to electrical noise, the encoder cooperates with internal resolver feedback during motion. Accurate mechanical registration is helped by a centering flange with a diameter of 50 mm, and motor length code B keeps installation depth moderate while supporting stable thermal behavior.
Dynamic behavior is shaped by standard balancing, which helps the shaft run smoothly at maximum speed. Cabling exits on the rear left because the power and feedback connectors are mounted on side B, and a sealed circular connector keeps wiring compact inside the cabinet. The motor is supplied without a blocking brake and without a shaft seal, and it has a standard shaft end on the drive side only. This layout suits clean installations where external shaft sealing at the motor is not required. The motor has size code 041, and the drive-side shaft uses a keyway to transmit torque into pulleys or couplings.
