Product Description:

The MDD090C-N-020-N2L-110PR0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It functions as a motor for digital drive controllers and supplies controlled rotary motion in automated packaging, handling, or machining stations. The designation includes a medium-length stator that increases magnetic surface area for moderate torque density. Standard rotor balancing keeps vibration within normal limits while permitting direct machine mounting. The motor is supplied without a blocking brake, so any power-off holding duty must be met by external mechanics.

Under continuous stall conditions, the motor can deliver 10.4 Nm of torque while the winding temperature remains steady, supporting axis loads that require constant holding force. During normal operation, the shaft reaches a nominal speed of 2000 rpm, a value chosen to match common industrial drive operation. Position data is returned through digital servo feedback (DSF), allowing high-resolution closed-loop control without separate encoder cabling. Mechanical integration is guided by the centering diameter of 110 mm, which aligns the flange to the machine frame, and power is transmitted through a shaft with a keyway so couplings can be locked against slip.

Electrical and service connections exit on the right side through a sealed connector, simplifying cabinet layout when multiple axes share a common plate. The front end carries a shaft seal that blocks lubricants or fine dust from entering the bearings, helping extend service life in coolant-rich environments. Frame code 090 keeps overall dimensions compatible with other MDD motors of similar rating, and length code C provides extra stack depth for higher magnetic flux. The housing uses a standard classification, and the shaft end on side B is left without machining.
