Product Description:

Bosch Rexroth Indramat manufactures the MDD090C-N-040-N2M-130PL1 in its MDD Synchronous Motors series. This motor is intended for digital drive controllers that govern coordinated positioning, speed, and torque in automated machinery. By energizing the stator windings and monitoring rotor position, it converts electrical energy into controlled mechanical rotation for axes that demand repeatable motion profiles. That makes it suitable for packaging, handling, and transfer systems where the controller must correct motion errors in real time rather than rely on open-loop behavior.

The unit reaches a nominal speed of 4000 rpm, allowing fast cycle execution in pick-and-place or packaging stations. At standstill, it can deliver 10.4 Nm continuously, which supports load holding and low-speed torque production within its thermal capacity. Motion feedback is provided by digital servo feedback, and rotor position is captured through an integrated multi-turn absolute encoder. This combination gives the drive position data across multiple revolutions and supports accurate loop closure without external sensors. A centering diameter of 130 mm aligns the flange to the adjoining machine frame, and the standard housing and winding package avoid the need for special cooling hardware or nonstandard mechanical preparation. The flange fit also helps keep the shaft axis aligned with couplings or gear inputs, which reduces installation-induced misalignment.

A blocking brake supplies 6.5 Nm to hold the load when power is removed, which helps prevent back-driving on vertical axes. Power and feedback leads exit to the left through a connector, so the cable path remains fixed at the machine interface. The solid shaft uses a keyway for positive torque transmission, and it is built with a standard shaft end that stops before side B. A resilient shaft seal helps protect the front bearing from splash and dust during normal industrial operation. This arrangement also supports dependable operation in enclosed machine spaces.
