Product Description:

The MDD090A-N-020-N2L-110GL0 belongs to the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Classified as a motor for digital drive controllers, it converts electrical commands from an Indramat drive into mechanical motion for positioning tasks on packaging lines and material-handling axes. Its 090 frame diameter and compact A-length body allow integration where envelope constraints are tight, while the standard housing suits general industrial machine layouts. This motor type is intended for closed-loop motion applications that require repeatable positioning and stable speed control during cyclical operation.

Its centering pilot measures 110 mm, a dimension that aligns the stator precisely with machine frames and helps maintain accurate shaft positioning. Power and feedback are routed through a plug-in connector, which simplifies cable connection without disturbing surrounding hardware. At standstill, the motor can deliver 3.7 Nm of continuous torque, giving the drive enough reserve to hold loads against static friction. Rotor position is reported by digital servo feedback (DSF), enabling precise commutation and closed-loop velocity control up to a rated speed of 2000 rpm. These characteristics set the electrical and mechanical operating limits that the paired drive must observe when applying current, acceleration, and speed commands.

The connection hardware is mounted on the left side of the stator so cable exits can follow a consistent routing path inside the machine. Because the motor is supplied without a blocking brake, holding force during power loss must be provided by commanded torque or an external brake. A plain shaft transfers torque through a suitable coupling, and a shaft seal is included to help limit lubricant migration toward the encoder cavity. Standard dynamic balancing helps keep vibration low at full speed, and the short motor length code A keeps the housing compact while preserving the thermal capacity of the 090 frame.
