Product Description:

The MDD090C-N-040-N2L-110PB1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to operate with digital drive controllers, the unit converts controlled three-phase electrical input into accurate rotary motion for positioning tables, pick-and-place arms, and similar automation axes. It is suited for applications that require repeatable speed control and accurate positioning during frequent start-stop cycles. Its housing format fits automated machinery where compact installation and dependable servo response are important.

The motor delivers a continuous stall torque of 10.4 Nm, allowing sustained load holding or low-speed operation without excessive heating. Under rated excitation it reaches a nominal speed of 4000 rpm, so the same motor can support both rapid indexing and steady running. A centering diameter of 110 mm helps align the stator housing concentrically with adjoining machine components. All power, feedback, and brake leads exit on Side B, which helps keep cabling away from the drive-end shaft connection. The integrated blocking brake provides 6.5 Nm of static torque, locking the shaft whenever drive excitation is removed and helping hold position on vertical or load-sensitive axes.

Closed-loop position data is returned through digital servo feedback (DSF), allowing the paired controller to regulate speed and position without a separate external encoder. A factory-installed shaft seal helps prevent coolant or lubricants from reaching the front bearing when the motor is installed in splash-prone areas. Torque is transmitted through a keyway shaft, which mates with standard keyed hubs and reduces the risk of slip during rapid reversals. Build length code C gives this frame a longer active iron stack, which supports continuous output with controlled heat rise. The rotor assembly uses standard dynamic balancing to support smooth operation across the motor's operating range.
