Product Description:

The MDD090A-N-020-N2L-130PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it supplies regulated torque and speed so automated axes can follow programmed motion profiles with consistent response. An integrated rotary encoder sends digital servo feedback to the controller, allowing closed-loop position and velocity control in material-handling, packaging, and printing equipment. This arrangement supports repeatable motion on axes that need accurate starts, stops, and speed changes during normal operation.

The motor reaches a nominal speed of 2000 rpm, which suits moderate-speed applications that also require high positional accuracy. At standstill, it can deliver a continuous torque of 3.7 Nm, while an internal blocking brake can provide up to 6.5 Nm to hold the load when power is removed. Power and feedback lines enter through a connector positioned on side A, which can simplify cable routing when several motors are installed close together. Standard dynamic balancing helps limit vibration during rotation, and the A winding length helps keep mass and inertia low. The motor uses a single shaft end and does not include a side B extension, which helps reduce overall length.

The mechanical interface includes a centering diameter of 130 mm, which matches many common flange connections used with compatible couplings and gear units. Frame size 090 indicates the motor's outer stator cross-section, while the short A-length helps conserve installation space in compact machine layouts. A machined keyway on the output shaft supports rigid torque transmission to the driven load. The fitted shaft seal helps limit the entry of fine dust and reduces the chance of lubricant migration near the shaft opening. The wiring arrangement uses connector-based connections, which keeps electrical attachment straightforward for digitally coordinated multi-axis systems.
