Product Description:

The MDD112B-F-040-N2L-130PA1 synchronous motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for connection to digital drive controllers, it converts regulated current into controlled torque for machining centers, material-handling stations, and general automation cells. The supplied housing, feedback, and mechanical options make it a direct-coupling choice for servo axes that require fast response and repeatable positioning accuracy.

The motor delivers a continuous standstill torque of 17.5 Nm, allowing the axis to hold static loads without overheating. Under rated excitation, it reaches 4000 rpm, enabling rapid point-to-point moves within the magnetic limits of the 112 frame. Precise centering against the mounting flange is supported by a 130 mm locating diameter that aligns the stator with the machine structure. Heat generated by copper losses is removed by liquid cooling, permitting higher duty cycles than air-cooled units. Power and feedback conductors exit on side A through a sealed connector, which simplifies cable routing when the motor faces the drive train. Standard dynamic balancing limits vibration, and the length code B body keeps the installation depth compact for retrofits.

A fail-safe holding brake rated at 14.0 Nm secures vertical or suspended loads whenever the drive is disabled. Position data are transmitted through the integrated digital servo feedback, which supplies high-resolution encoder information for closed-loop control. The output shaft uses a keyway profile for positive coupling with pulleys or gear hubs, and it is fitted with a shaft seal to help prevent lubricant migration along the journal. A molded circular connector completes the power circuit in line with the connection type, while the single-ended shaft arrangement leaves the opposite end free for blower ducts or coolant hoses, which helps when positioning the liquid supply lines.
