Product Description:

The MDD090B-N-020-N2L-110GL2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for operation with digital drive controllers, it converts commanded three-phase current into precise rotary motion for tooling, packaging, and material-handling axes in automated plants. Its electromagnetic design supports dynamic positioning while keeping installation requirements straightforward. This operating behavior helps the motor respond quickly to changing command values during closed-loop motion tasks.

The motor provides a continuous standstill torque of 7.2 Nm, which supports static loads without causing thermal overload under rated conditions. During motion, the rotor reaches a nominal speed of 2000 rpm, which suits common spindle and transfer-line duties. An integrated blocking brake provides 11.0 Nm of holding torque when power is removed, which is useful on vertical or suspended mechanisms. Position data is returned through digital servo feedback (DSF), so separate external encoder hardware is not required. A centering diameter of 110 mm allows repeatable concentric mounting with adjacent gearboxes, and standard dynamic balancing helps keep residual vibration low during operation.

Electrical and signal leads exit on the left side, allowing cabinet layouts to follow the specified connection direction. The motor uses a keyed connector interface that helps prevent miswiring and allows quick disconnection when the unit must be removed. Shaft protection is improved by a fitted shaft seal, which helps keep coolant and dust out of the bearing chamber. Torque is transmitted through a plain shaft, and the motor has no second shaft end on side B, which reduces overall length in tight spaces. The motor has frame size 090 and a B length, which gives it a medium stack height within the series. It is supplied with a standard housing finish for general industrial use.
