Product Description:

The MDD093B-N-040-N2M-130GR2 is a motor for digital drive controllers built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It translates command currents from a drive into precise rotary motion for positioning or velocity-controlled axes in automated assembly cells, material-handling gantries, and packaging equipment. The unit combines an enclosed stator, a permanent-magnet rotor, and integrated position sensing to give the controller accurate and responsive mechanical output. Its synchronous design supports repeatable acceleration and stable speed regulation in closed-loop motion tasks.

The motor can hold a static load with 14.5 Nm of continuous standstill torque, so an axis remains stable during dwell periods or pressing operations. During motion, its nominal operating speed of 4000 rpm allows fast cycle execution without requiring an external gearbox. An integrated spring-applied brake supplies up to 22 Nm of mechanical holding torque, locking the shaft when power is removed and helping prevent slide-back on vertical axes. The housing is aligned by a centering pilot that measures 130 mm in diameter, which supports accurate concentric installation on the machine face. Electrical and feedback conductors exit on the right side, so cable routing can follow the machine frame without crossing the moving assembly.

The motor uses frame size 093, and the B length provides a medium housing size that balances inertia and thermal surface area. Position information is supplied through digital servo feedback, allowing the drive to read absolute rotor position at startup and maintain closed-loop control during operation. A plain shaft end simplifies connection to toothed belts or clamping hubs, and the front bearing cavity is protected with a shaft seal so lubricants remain contained while coolant spray and debris are kept away from internal parts. This layout suits compact multi-axis equipment that needs accurate feedback, dependable holding capability, and sealed shaft output.
