Product Description:
The MDD090A-N-020-N2M-110PA2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is used with digital drive controllers, serving as the rotary actuator in closed-loop automation axes that require position and velocity control. In production lines or material-handling stations, this motor converts electrical energy from the drive into mechanical torque at predictable speed, allowing precise coordination with sensors and PLC logic. Its design supports responsive motion control in positioning tasks that require repeatable starts, stops, and speed changes.
It delivers a continuous standstill torque of 3.7 Nm, indicating the sustained twisting force available without overheating when the rotor is locked. The nominal operating speed of 2000 rpm is the rated running speed under standard load, while a blocking brake provides holding capability up to 11.0 Nm so vertical loads do not drift during shutdown. Machine mounting is centered by a 110 mm pilot diameter that aligns the housing and helps transmit reaction forces into the machine face. Power and feedback conductors exit on Side A, which can simplify cable routing when multiple axes share the same orientation. The rotor is balanced to the standard grade to help reduce vibration during acceleration and steady operation.
Position data are supplied by the integrated multiturn absolute encoder, and the drive reads this through digital servo feedback to close the motion loop without extra converters. A factory-installed shaft seal protects the keyed shaft against coolant splash, while the keyway allows secure torque transfer to the driven load. The motor uses series length code A and the compact size 090, which helps it fit machines that require a short installation length. A single connector handles power and signal wiring, and the lack of a side-B shaft end keeps the installation compact. This layout supports direct integration into servo axes where mounting space and cable clearance are limited.
