Product Description:

The MDD090A-N-040-N2L-130PB1 synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it interfaces with servo amplifiers that modulate phase current to achieve commanded motion profiles. In automated production lines, the unit supplies repeatable rotary movement for indexing tables, feed drives, and transfer modules, where accurate acceleration and deceleration are essential for cycle-time consistency and dimensional precision. Its closed-loop operation also helps the connected drive maintain stable motion when load conditions change during rapid start-stop sequences.

At stall, the motor can deliver a continuous torque of 3.7 Nm, allowing it to hold or slowly drive loads without thermal overload during prolonged dwell periods. With the brake released, the motor supports a nominal speed of 4000 rpm, matching common linear-feed and spindle duties in mid-range machinery. For safety during power loss, an integrated blocking brake applies up to 6.5 Nm of static torque to prevent unintended movement. Rotor position is measured through digital servo feedback (DSF), enabling the drive to correct position errors within each control cycle. Installation is centered by a 130 mm pilot diameter that aligns the housing with the machine frame and maintains concentricity.

The motor uses frame size 090 with length code A, which keeps the overall package compact for multi-axis layouts. Power and feedback conductors exit on side B through a single industrial connector, which simplifies cable routing inside enclosures. Drive torque reaches the load through a shaft with a keyway, and a dedicated shaft seal helps limit lubricant ingress and egress. Standard dynamic balancing, a single-ended shaft configuration, and an unvented housing help control vibration and support direct mounting to geared reducers or belt pulleys.
