Product Description:

The MDD115B-N-020-N2L-130GA2 is a synchronous AC motor built by Bosch Rexroth Indramat for use with digital drive controllers in automated machinery. It belongs to the MDD Synchronous Motors series and provides closed-loop torque and speed control for axes that require precise positioning, indexing, or coordinated motion in assembly lines and material-handling cells. In automated systems, the motor converts commanded electrical input into controlled rotary motion for repeatable axis movement. This operating style makes it suitable for feed axes, transfer units, and other machine motions that must start, stop, and hold position with consistent response. Position data is returned through digital servo feedback, so the controller can correct errors within each operating cycle.

It uses a centering pilot of 130 mm, allowing the housing to mate directly against machine plates with accurate alignment. At standstill, the electromagnetic system can deliver 38.0 Nm of continuous torque, so the axis can resist static loads while remaining ready for motion without overheating. During motion, the rotor reaches a nominal speed of 2000 rpm, giving the drive a standard operating point for velocity control. Power and encoder leads exit on the motor's side A, which can simplify cable routing when the flange faces the machine.

For load-holding duties, the integral blocking brake supplies 60.0 Nm of static torque, so vertical or offset axes can be secured when power is removed. Electrical power is introduced through a sealed connector, which supports protected cable attachment at the motor housing. The motor uses frame size 115, providing a larger stator cross-section while staying within common MDD mounting patterns. A plain output shaft is protected with a shaft seal, which helps limit lubricant migration and the entry of process fluids at the coupling interface.
