Product Description:

The MDD090B-N-020-N2L-110GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is installed in automated machine axes to deliver commanded torque and speed under closed-loop control. By pairing the rotor’s permanent-magnet field with a regulated current source, the unit supports positioning, indexing, and continuous rotation tasks common in packaging equipment, printing presses, material-handling stations, and other automated machinery that needs accurate motion control. The motor is intended for repeatable servo operation in systems that rely on accurate feedback and stable current regulation.

The motor has a centering diameter of 110 mm, which helps align it concentrically on matching flanges or gearbox interfaces. At standstill, it can deliver 7.2 Nm of continuous torque, allowing moderate static load support without overheating the windings during normal operation. The electromagnetic design supports a nominal speed of 2000 rpm, so the connected drive can command smooth motion across low and mid-range velocities while maintaining stable response. Rotor position is reported through digital servo feedback, and power and feedback conductors exit on side B through an integrated connector that simplifies cable attachment and avoids hard-wired glands.

A factory-applied standard balancing grade helps reduce shaft vibration across the speed range and matches most common coupling arrangements. The motor uses a plain shaft with a shaft seal, which supports low runout while helping keep contaminants away from internal bearing areas. It is supplied without a blocking brake, so any holding function at standstill must come from drive torque or external mechanical retention. The housing uses motor size 090 with length code B and a single-ended shaft layout, which suits machine axes that need precise rotary motion in a compact motor format.
