Product Description:

The MDD041A-N-100-N2G-050MB1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it provides compact torque generation for precise axis motion in automated machinery. This A-length unit uses a standard balancing grade, has the standard housing option, and is built with a single shaft end on the drive side only, leaving side B without an output flange. That layout keeps the non-drive end free of a second mechanical output and suits installations where clearance around the rear of the motor is limited. The short housing length also helps the motor fit compact axis layouts without extending far from the mounting surface.

During operation, the motor can maintain a continuous standstill torque of 0.64 Nm, giving a clear reference for static load support at rated current. Speed capability reaches 10000 min⁻¹, which suits fast positioning tasks when the motor is paired with a compatible drive. This combination of continuous standstill torque and high speed supports both holding force at zero speed and quick point-to-point motion during travel. Electrical power and feedback conductors are routed on Side B, and all terminations are made through a keyed connector for orderly cable routing. Accurate concentric mounting is assisted by the front centering pilot of 50 mm diameter, which helps align the motor with the machine interface and reduce runout. Placing the connection point on the cable side opposite the shaft interface can simplify routing in tight machine spaces.

For holding duties, the motor is fitted with a blocking brake rated at 1.2 Nm, so the axis can remain in place when drive power is removed. The brake can help prevent axis drift when the machine is stopped and the drive is not actively producing torque. System feedback is provided through resolver feedback, which supplies rotor position information and works well in electrically noisy industrial environments. The motor uses the compact frame size 041, keeping the overall envelope small even with the integrated brake. A machined keyway shaft transmits torque without slip, and the absence of a shaft seal reduces friction where external contamination is not a primary concern. This shaft arrangement is suited to couplings or driven elements that require positive torque transfer in relatively clean installations.
