Product Description:

The MDD090A-N-020-N2L-110PA1 is a synchronous AC motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it forms the electromechanical stage of closed-loop servo axes used in automated assembly stations, material-handling gantries, and light machining centers. Typical use includes axes that must respond quickly to changing command values during production. The unit converts commanded current into regulated rotary motion, and its integrated position feedback enables the drive to hold speed and position with the repeatable accuracy required in industrial automation tasks.

Its nominal operating speed is 2000 rpm, meaning the rotor can maintain that speed under rated voltage and thermal conditions. At standstill, the motor can exert a continuous torque of 3.7 Nm, which is the maximum static load it can hold without overheating. Rotor position is reported through digital servo feedback (DSF), so the controller can keep the current loops synchronized during operation. Mechanical centering during installation is aided by a 110 mm centering diameter that aligns with standard flange patterns. Power and feedback conductors exit on side A, keeping cable routing consistent when multiple axes are stacked in a cabinet.

A blocking brake integrated at the stator supplies a holding torque of 6.5 Nm, allowing vertical or interrupted-motion axes to stay fixed when power is removed. The output shaft uses a keyway, so standard keyed couplings can transmit torque without slipping. The front bearing region includes a shaft seal, which helps limit the ingress of coolants or dust. Electrical terminations use a sealed connector that mates with Indramat hybrid cable sets and supports secure cable attachment. Standard dynamic balancing, the Series 090 frame size, and the short A length code help keep rotor inertia low while allowing the motor to fit into compact machine spaces.
