Product Description:

The MDD112B-N-015-N2L-130PB0 is a servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for integration with digital drive controllers, it converts regulated electrical power into controlled rotary motion for positioning and speed-regulated tasks in automated machinery. Its electromagnetic design supports closed-loop control where torque linearity and repeatability are important for process quality. This makes the motor suitable for applications that require accurate speed regulation together with repeatable positioning over frequent duty cycles.

At standstill, the motor delivers 17.5 Nm of continuous torque, allowing stable load support without overheating during low-speed or holding operation. During normal operation, it reaches a nominal speed of 1500 rpm, which suits machine axes that favor moderate velocity with high torque density. A centering diameter of 130 mm aligns the housing precisely to mounting flanges and helps reduce radial runout at the machine interface. Rotor and assembly are balanced to the standard grade, so residual vibration remains low even when the power and feedback connections are arranged on side B of the stator. Position and velocity data are returned through digital servo feedback (DSF), enabling the drive controller to close control loops with incremental and absolute information. The motor uses frame size 112 with B length, giving it an axial dimension suited to medium-inertia duties while maintaining consistent thermal paths.

Power and encoder conductors plug directly into a connector, eliminating the need for hard-wired glands and simplifying cable routing at the motor housing. The solid output shaft uses a keyway to transmit torque, and there is no shaft extension on the opposite side, so the motor uses a single-ended shaft design. Contamination ingress is limited because the front bearing area is supplied with a shaft seal. Overall holding force must be provided by external measures since the motor ships without a blocking brake. The cast-aluminum housing has a standard finish, and its surface area supports natural convection during continuous duty.
