Product Description:

Bosch Rexroth Indramat manufactures the MDD090B-N-030-N2L-110GR2, a member of the MDD Synchronous Motors series. This AC synchronous motor is intended for use with digital drive controllers in automated machinery, where it converts commanded current into precise rotary motion for positioning, conveying, or spindle duties. It provides an integrated feedback channel and a mechanical interface sized for medium-frame axes in assembly lines, packaging equipment, and other motion systems that require controlled speed and position response.

The motor delivers a continuous standstill torque of 7.2 Nm, allowing it to hold or slowly move loads without overheating under rated current. During operation, the rotor can reach a nominal speed of 3000 rpm, which supports stable synchronous operation in matched drive systems. A centering pilot of 110 mm helps align the flange and maintain concentric mounting with gearboxes or direct-coupled loads. The windings are dynamically balanced to the standard quality grade to reduce vibration during rotation, and the die-cast housing follows the standard enclosure format used across the series. Power and feedback conductors are routed through connections oriented to the right side, and the motor uses a keyed connector housing instead of fixed lead wires. This arrangement supports orderly cable routing where side access is preferred and keeps the electrical interface separate from the driven shaft area.

A blocking brake is integrated and can clamp the shaft with 11.0 Nm of static torque, which helps hold vertical or overhung loads when drive power is removed. Motion commands are closed by digital servo feedback, providing position information required for accurate speed and position control. The output interface uses a plain shaft, so couplings or pulleys can be mounted directly without a keyed profile. The motor is supplied without a shaft extension on side B, which reduces unsupported overhang at the rear end of the housing. Built on the 090 size with length code B, the frame fits mid-range equipment while preserving thermal capacity for intermittent overload conditions.
