Product Description:

The MDD090B-N-040-N2L-110GA0 synchronous motor is built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it converts three-phase stator currents from the drive into controlled rotary motion for conveyors, pick-and-place heads, and rotary tables in automated assembly lines. Its servo design allows the connected controller to regulate acceleration, deceleration, and holding behavior with repeatable response during frequent start-stop cycles. The motor uses the 090 frame and B length class, fits in a standard housing, and has a factory-molded connector block, which helps it fit into tight machine compartments without additional adapter plates.

Mechanical alignment is set by a centering pilot of 110 mm, allowing concentric coupling to gearboxes and precision flanges without shims. At standstill, the rotor supplies 7.2 Nm of continuous torque, which helps support static loads without overheating. During motion, it can maintain a nominal speed of 4000 rpm, supporting rapid indexing and short cycle times. Positional accuracy is maintained through digital servo feedback, which sends high-resolution signals to the controller for closed-loop regulation of speed and position. That feedback channel lets the controller monitor rotor position continuously during both indexing and steady-speed operation. The motor is delivered without a blocking brake, so static holding after power removal must be provided by the drive or by an external clamp.

The motor uses standard balancing, which helps reduce shaft vibration across the full speed range. All power and feedback conductors exit on side A, so the cable bundle remains on one face of the machine frame and away from moving parts. This cable exit arrangement also helps keep bending loads away from the coupling area and leaves more clearance around adjacent machine components. The output is a plain shaft in a single-ended configuration, so there is no secondary shaft on side B. Protection against coolant splash and lubricants is provided with a shaft seal, which helps preserve bearing life and supports use in enclosed machine spaces.
