Product Description:

The MDD090C-N-040-N2L-110GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for use with digital drive controllers and belongs to the MDD Synchronous Motors series. Designed for positioning and cyclic-duty tasks in industrial automation cells, the unit converts commanded electrical energy into regulated mechanical rotation for packaging, material handling, and machining equipment. In closed-loop operation, the motor works with the connected drive to maintain accurate speed and position during repeated starts, stops, and short dwell periods. Because it is intended for digital drive controllers, it suits applications that need fast command response and repeatable axis motion. This makes it suitable for compact machine layouts where consistent servo performance is required.

At standstill, the motor can deliver a continuous torque of 10.4 Nm, enabling stable load support without overheating. During acceleration or vertical holding events, its blocking brake supplies up to 11.0 Nm of static torque, and the brake is released electrically when motion is commanded. Rated speed reaches 4000 rpm, which suits medium-inertia axes that require rapid indexing. Position and velocity information is returned to the drive through digital servo feedback (DSF), allowing closed-loop current and speed control. The feedback channel gives the controller continuous rotor data so motion corrections can be made quickly as load conditions change. All power and signal conductors terminate on a single connector, which simplifies cable routing. The motor is built in length code C, uses standard dynamic balancing, includes an integral shaft seal, and relies on the standard cooling surface without auxiliary fans.

A centering pilot of 110 mm locates the flange accurately on the machine face. The power and feedback plugs exit on side B, allowing the harness to be routed away from moving parts. Torque is transmitted through a plain shaft, and no secondary shaft extension is provided. The motor uses frame size 090, which fits the mechanical envelope associated with this housing size. The standard shaft arrangement is suitable for couplings that do not require a keyed interface. Cable exit placement can also help when surrounding guards or machine members limit available routing space.
