Product Description:

The MDD090A-N-040-N2L-110PA2 is an AC synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as the rotary drive element in industrial automation systems that use digital controllers, converting commanded electrical power into precisely regulated shaft rotation for indexing tables, pick-and-place arms, and similar machinery. When paired with matching drive electronics, the motor supports closed-loop motion sequences in which speed, position, and torque must be reproduced consistently under changing load conditions.

At standstill, the motor can deliver 3.7 Nm of continuous torque, allowing it to hold or slowly index loads without overheating. Under rated excitation, the rotor reaches a nominal speed of 4000 rpm, giving a favorable ratio between velocity range and mechanical stress for mid-frame machines. A built-in blocking brake supplies 11.0 Nm of static torque so vertical or suspended axes maintain position when the power stage is disabled. Position and velocity are returned to the drive through digital servo feedback (DSF), which provides high-resolution angle information for tight control loops. Mechanical alignment during mounting is aided by the 110 mm centering diameter that fits standard flange patterns for this motor size.

Cabling is straightforward because the power and feedback plugs are located on Side A, and a single multi-pin connector handles the terminations. The shaft has a keyway, so couplings with keyed hubs can transmit torque without slip, and a shaft seal is fitted to limit dust and oil ingress into the front bearing. Standard dynamic balancing minimizes residual vibration, while the housing and shaft end conform to the normal construction codes for size 090 motors. The short A-length stator keeps mass low, helping the drive accelerate rapidly when paired with matching inverters.
