Product Description:

The MDD112B-N-040-N2M-130PB1 belongs to the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a motor for digital drive controllers that converts electrical power from the drive into precise rotary motion for industrial automation axes, packaging equipment, and material-handling stations. The integrated multiturn absolute encoder feeds position data back to the controller, so the axis can operate in closed-loop control without additional sensors. This arrangement also helps the control system track rotor position during motion and maintain accurate positioning after power-up.

This model delivers a continuous standstill torque of 17.5 Nm, allowing it to hold a stationary load while energized within its rated thermal range. During running operation, the rotor can reach a nominal speed of 4000 rpm, giving fast cycle times when paired with matching gear ratios. The motor is aligned to the mounting surface through a centering diameter of 130 mm, which helps keep the shaft and driven load concentric. Feedback to the drive is conveyed as digital servo feedback, supporting high-resolution position control and automatic electronic nameplate recognition. Power and feedback leads exit on side B of the housing through a right-angle connector, which helps when rear clearance is limited.

A blocking brake is installed and can hold up to 14.0 Nm when power is removed, helping vertical axes remain stationary during stops. The output shaft uses a keyway, so it can connect directly to standard couplings or pulleys for positive torque transfer. A built-in shaft seal helps prevent lubricant migration and reduces the entry of dust or coolant near the bearing area. The motor has a frame size of Size 112, giving it a larger frame than smaller MDD models and supporting higher torque capacity without increasing overall complexity.
