Product Description:

The MDD090B-N-040-N2M-110GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is designed for digital drive controllers, where inverter current is converted into accurate rotary motion for positioning axes and continuous-duty spindles in automated machinery. Its synchronous operating principle supports precise response to commanded speed and position changes during automatic machine cycles. This makes the motor suitable for applications that require smooth acceleration, repeatable motion, and stable operation during frequent starts and stops.

Mechanical interface dimensions start with a centering recess of 110 mm, allowing accurate alignment against gearbox flanges or mounting bells. Cabling exits on the left side, which can simplify routing when the cabinet or cable track is placed in that direction. At standstill, the motor can deliver 7.2 Nm of continuous torque, providing steady force for slow-moving or stationary loads. A built-in blocking brake adds 6.5 Nm of holding torque when power is removed, which helps prevent axis drift in vertical applications. During motion, the rotor reaches a nominal speed of 4000 rpm, making it suitable for fast indexing, pick-and-place movement, and other high-cycle machine tasks. These operating values support both holding behavior at rest and quick response during active motion.

A shaft seal is fitted at the output end to help keep dust and fluid away from internal bearing areas. Position data is supplied by an integrated multi-turn absolute encoder, so the controller can read shaft position immediately after power-up without a reference run. The motor uses frame size 090, which gives it the mounting proportions associated with that housing class. Internal rotating parts are balanced to a standard quality grade, helping support smooth operation in general industrial service. This combination of sealing, feedback, frame geometry, and balancing helps the motor work well in enclosed machine spaces where clean operation and reliable positional awareness are important.
