Product Description:

The MDD090C-N-020-N2M-130GR2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to work with digital drive controllers, it translates commanded current into controlled mechanical motion for axes that require repeatable speed and torque. The unit uses a mid-frame stator and the C length code, giving it a footprint that suits conveyors, pick-and-place arms, and general handling modules in automated cells. Within an installation, the motor operates in a closed loop with electronic commutation and high-resolution feedback to maintain position accuracy under variable loads.

The motor reaches a nominal speed of 2000 rpm, which sets the synchronous electrical frequency and the operating speed used for standard duty cycles. At standstill, it can apply 10.4 Nm of continuous torque, keeping tooling clamped or tables held without excess heating. For static holding on vertical axes, the integrated blocking brake supplies 11.0 Nm of restraining torque. Position and velocity data return to the controller through digital servo feedback (DSF), providing differential signaling that resists electrical noise. Mechanical centering during mounting is guided by the 130 mm pilot diameter. The rotor uses standard balancing, and the sealed aluminum housing follows the series standard form. A single industrial connector carries power, brake, and feedback conductors.

The drive interface also includes an integrated multiturn absolute encoder, which retains absolute shaft position over many revolutions and reduces the need for a reference move after power is restored. All cable exits use a right-side cable exit, which helps when the electrical cabinet is mounted beside the motor. Torque is transferred through a plain shaft with a shaft seal, and the motor is supplied without a side-B shaft extension. Frame size 090 gives the motor a balanced mix of torque density and installation space for mid-range automation equipment. This layout suits couplings and gearhead connections that need a compact motor body and a sealed shaft area.
