Product Description:

The MDD090A-N-040-N2L-110PA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it supplies closed-loop rotary power to automated equipment that requires repeatable speed and position control. The motor uses frame size 090 with a compact A-length stator, so it fits installations that need a short motor body without giving up the response expected from a medium-duty axis. This layout makes it suitable for machinery that must combine accurate motion with limited installation space.

The motor reaches a nominal speed of 4000 rpm, allowing direct coupling to fast-cycling machinery without added gear reduction in many applications. At standstill it delivers 3.7 Nm of continuous torque, which helps the axis resist static load while the servo remains energized. An integrated blocking brake provides 6.5 Nm of holding torque for shutdown or emergency-stop conditions. Because the brake uses an independent holding circuit, shaft retention does not rely only on servo torque when main motion power is removed. Rotor alignment is supported by a 110 mm centering diameter, and power and feedback connections are routed through a sealed connector on Side A. Integrated Digital servo feedback (DSF) supplies commutation and position data to the drive for closed-loop regulation.

The shaft uses a keyway so torque can be transferred securely to couplings or pulleys without slip under rated load. A shaft seal helps limit the entry of oil, coolant, and similar contaminants at the output end. The motor has a standard housing and standard balancing, and it does not include a secondary shaft extension on side B. These features support stable running in automated machinery and suit applications that use a single mechanical output point.
