Product Description:

The MDD090C-N-020-N2M-130GA1 is a synchronous motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is supplied for use with digital drive controllers in automated machinery, where inverter output is converted into controlled rotary motion. This arrangement supports closed-loop axis control for positioning tasks in packaging, printing, and material-handling equipment. The motor is intended for applications that require repeatable motion response and stable speed regulation during normal production cycles.

The mechanical envelope uses size code 090, and the flange has a centering diameter of 130 mm for repeatable mounting to gearboxes or direct-drive loads. Electrical and feedback conductors are routed on side A through a single connector, which keeps cable routing concentrated on one end of the housing. Continuous torque at standstill reaches 10.4 Nm, so the motor can carry a steady holding load without thermal overload. Under nominal operating conditions, the rotor runs at 2000 rpm, balancing speed output with magnetic losses during regular duty. The motor also uses standard dynamic balancing, a plain shaft with a factory-installed shaft seal, standard die-cast housing construction, and a single-sided shaft arrangement with no extension on side B.

A blocking brake is integrated for vertical or overhung loads, and its holding torque is rated at 6.5 Nm, engaging automatically when power is removed. The motor has axial length code C, which gives it greater stack height and added thermal mass than shorter units in the same frame. Rotor position is measured by an integrated multiturn absolute encoder, allowing the drive to recover shaft angle after a power interruption without a homing cycle. Motion commands and diagnostic data are carried through digital servo feedback, supporting high-resolution commutation and stable velocity control when the motor is paired with a compatible drive.
