Product Description:

The MDD090B-N-040-N2L-130GL0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is categorized as a motor for digital drive controllers and is intended to deliver closed-loop rotary motion in automated machinery where rapid speed changes and accurate positioning are required. Its synchronous motor design supports stable torque response during acceleration, deceleration, and short positioning moves. This makes the unit suitable for axes that must follow commanded motion profiles with repeatable rotary output during normal machine operation.

The unit develops a continuous standstill torque of 7.2 Nm, giving the drive sufficient holding force during low-speed processes. Under rated excitation, it reaches a nominal speed of 4000 rpm, allowing high cycle rates when paired with compatible inverters. Position feedback is provided through digital servo feedback (DSF), which transmits absolute rotor data to the controller in real time. Mechanical alignment is aided by a 130 mm centering diameter that matches standard mounting flanges. Power and signal leads exit through a left-oriented connection, which can help keep cable routing clear of nearby machine elements. These conductors are carried on a single industrial connector, which keeps the interface compact and helps maintain housing integrity.

Moment balance is achieved with standard rotor balancing, limiting vibration across the full speed range. The motor is built to length code B, giving a mid-length stator that fits confined drive bays without reducing thermal capacity. A plain shaft is supplied for direct use with clamp or keyless hubs, and a shaft seal helps block oil or particulate ingress at the output end. The design omits a blocking brake, so static holding torque must be generated electronically when power is removed. The housing uses a single shaft end on side A, which supports installation in packaging lines, transfer stations, and index tables.
