Product Description:

The MDD090A-N-040-N2M-110GA0 synchronous motor is produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers and converts electrical power into controlled mechanical rotation for packaging lines, material-handling gantries, and assembly stations. This arrangement supports accurate indexing, stable speed regulation, and repeatable positioning during automated motion cycles.

At a nominal speed of 4000 rpm, the rotor can reach its rated operating speed without field weakening, which gives the axis a consistent upper speed range. The continuous standstill torque of 3.7 Nm shows the load the shaft can hold indefinitely with rated current while locked, which is useful for axes that must resist a steady load at zero speed. Accurate mechanical alignment is supported by a centering diameter of 110 mm, which mates with register sleeves on the mounting flange. All power and feedback connectors face side A, which helps keep cable routing orderly when several axes are installed in line. Position feedback is delivered by an integrated multi-turn absolute encoder that reports absolute shaft angle over many revolutions, so the system can retain position information after a power interruption.

Signal integrity between the motor and the drive is maintained through Digital servo feedback (DSF), enabling high-resolution velocity loops at the controller. A plain shaft couples directly to pulleys or bellows couplings, and a shaft seal helps protect the output end from lubricant ingress. The compact enclosure identified by length code A shortens the magnetic path, which helps reduce inertia for rapid acceleration in pick-and-place modules. Because the motor is supplied without a blocking brake, external clamping is required if power-off holding is needed.
