Product Description:

The MDD115B-N-030-N2M-130GA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for pairing with digital drive controllers so that industrial axes obtain precise torque and position regulation. It converts controlled electrical input into accurate rotary motion for positioning and speed-controlled applications. Its synchronous design supports coordinated motion where speed changes and position corrections must be carried out quickly. A standard housing, a plain shaft, and side-mounted connectors allow direct installation, while the built-in blocking brake keeps the load fixed when power is removed.

This motor delivers a continuous standstill torque of 38.0 Nm, enabling stable holding and low-speed operation without overheating. During motion, it can maintain a nominal mechanical speed of 3000 rpm, which suits many direct-drive and geared axis arrangements. An internal brake produces up to 45.0 Nm of static torque so vertical or suspended loads do not back-drive the shaft. Accurate mechanical centering is supported by a 130 mm locating diameter, which helps keep the motor aligned with the driven machine element. All power and feedback leads exit on the A-side, which can simplify cable routing where one side of the motor remains more accessible. Position information is exchanged over Digital servo feedback (DSF), allowing the controller to close high-bandwidth loops without external sensors.

The sensing chain starts at the integrated multiturn absolute encoder, which reports shaft angle across multiple revolutions so homing cycles are unnecessary after power cycles. A frame size of 115 aligns the motor with standard mounting flanges used in mid-torque gantries and similar axis assemblies. A factory-installed shaft seal helps keep oil and coolant away from the front bearing area during normal operation. The encoder data also allows the drive to retain absolute position information through start-stop cycles, which is useful on axes that cannot tolerate a reference run before operation.
