Product Description:

The MDD090A-N-030-N2M-110GA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built for integration with digital drive controllers, it converts electrical power into precise rotary motion for axes that require consistent speed regulation and responsive torque. The unit uses the 090 frame size with the A length code, giving it a compact form for machines where several motors must fit into limited installation space. This arrangement suits positioning axes, indexing stations, and other automated assemblies that need accurate servo response in a relatively small motor package.

Under rated conditions, the rotor runs at 3000 rpm, providing a fixed mechanical speed reference for the connected drive. Continuous stall capability is 3.7 Nm, so the motor can hold static loads without overheating when it remains locked in position. For emergency stops or vertical axes, its blocking brake applies 11.0 Nm of static torque to help prevent back-driving during power loss. Position and velocity are closed by Digital servo feedback (DSF), enabling the drive to track rotor movement accurately through the integrated multiturn encoder. A centering diameter of 110 mm registers the motor concentrically with the machine flange and helps reduce runout. Power and feedback conductors enter through a sealed connector, which allows cable changes without opening the housing.

Terminals are oriented toward Side A, so cable routing remains predictable in machines built around a common layout. The rotor uses a Plain shaft that mates with clamping couplings or shrink disks, while a shaft seal helps keep lubricants and contaminants away from internal components. Dynamic imbalance is limited by the Standard balancing grade, which helps reduce vibration during repeated duty cycles. The motor also uses a standard housing and an integrated multiturn absolute encoder, and it does not have a second shaft end. That combination reduces exposed rotating surfaces and simplifies guarding when the motor is mounted close to neighboring machine elements.
