Product Description:

The MDD090A-N-040-N2M-110GR2 synchronous motor is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts regulated current into precise rotary motion for indexing, feed, and auxiliary axes inside automated machinery. Its compact build suits equipment that needs accurate response and repeatable servo positioning.

At standstill, the rotor delivers a continuous torque of 3.7 Nm, letting the axis hold load without overheating during normal thermal conditions. During motion, the winding reaches a nominal speed of 4000 min⁻¹, which supports fast positioning cycles on medium-duty machine axes. A blocking brake rated at 11.0 Nm helps prevent back-driving when power is removed or when a vertical load must remain fixed.

A centering diameter of 110 mm aligns the motor accurately to the machine interface, and the power and feedback conductors exit on the right side through a sealed connector for cleaner cable routing. Frame size 090 gives the motor a moderate stator diameter, while length code A keeps the housing short to reduce overall package depth. An integrated multiturn absolute encoder provides position data immediately at startup for commutation and axis referencing. The output uses a plain shaft with a shaft seal for direct coupling while helping limit lubricant escape.
