Product Description:
The MDD090C-N-020-N2M-130PB1 servo unit is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts supplied current into regulated rotary motion for positioning or speed-control tasks in industrial automation cells. When paired with a compatible drive, the motor forms part of a closed-loop axis that can index, dwell, and reverse under PLC command. Its synchronous design supports stable torque production and responsive speed regulation during repeated starts, stops, and direction changes.
At standstill, the motor can deliver a continuous torque of 10.4 Nm, allowing it to hold loads without overheating until motion is commanded. Under rated electrical and thermal conditions, it operates at a nominal speed of 2000 rpm, which suits medium-speed axes that favor direct coupling. Accurate centering is aided by a 130 mm pilot diameter that keeps the stator concentric with attached gearboxes or machine interfaces. For vertical axes, the built-in brake provides 6.5 Nm of holding torque to help prevent drift when power is removed. Oil ingress is restricted by a shaft seal. The motor also has length code C, size 090, a keyway shaft on the drive side only, a standard cast housing, and a single rear-mounted connector for power and feedback. That connector carries both power conductors and digital measurement lines through one interface.
Precise closed-loop control is provided by an integrated multi-turn absolute encoder that reports position over multiple revolutions through digital servo feedback. This feedback method lets the drive retain position information across revolutions and supports accurate axis control during normal operation. All conductors exit on Side B, which helps route cables away from moving machine elements and keeps the connection area on one end of the motor. Vibration is limited by standard balancing, so the keyed shaft transmits smooth torque to couplings and pulleys during normal servo operation.
