Product Description:
The MDD090A-N-030-N2L-130GB2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It serves as the electromechanical actuator in systems that use digital drive controllers, translating commanded current into precise rotary motion for positioning tables, feeders, and packaging machinery. The A-length code, 090 frame size, and standard housing give the unit a compact footprint, while an integral blocking brake maintains axis position whenever the inverter is disabled. This layout makes the motor suitable for axes that need accurate motion control without requiring a large installation envelope.
The motor supplies a continuous standstill torque of 3.7 Nm, allowing it to resist load forces during low-speed operation without thermal overload. A nominal mechanical speed of 3000 rpm matches common controller frequency ranges and supports stable velocity loops during normal operation. When power is removed, a spring-applied brake delivers 11.0 Nm of holding torque so suspended loads remain stationary. Accurate alignment is aided by a flange centering diameter of 130 mm, which fits standard mounting bores and helps maintain concentric installation. Rotor position is transmitted through digital servo feedback, permitting high-resolution commutation and responsive closed-loop control across dynamic duty cycles.
Cable routing is streamlined because power and feedback exits are located on Side B of the housing, keeping harnesses clear of moving machine parts in many machine layouts. A circular industrial connector allows quick disconnection while helping preserve the sealed connection point. To minimize lubricant loss and block contaminants, a dedicated shaft seal surrounds the metric journal, which is supplied as a plain shaft for direct coupling with backlash-free clamping hubs. This shaft arrangement supports precise torque transmission without requiring a keyed connection. The combination of rear cable exit, sealed shaft area, and direct-coupling shaft geometry fits motion axes where compact motor mounting and dependable feedback routing are both important.
