Product Description:

The MDD112C-N-020-N2L-130GA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is a permanent-magnet AC unit intended for operation with digital drive controllers. In that role, it supplies closed-loop torque and speed for automated machinery and supports accurate response to changing motion commands. This motor type is commonly used on positioning axes and other equipment that requires repeatable motion under varying load conditions.

The motor can deliver a continuous standstill torque of 28.0 Nm, allowing stable holding or low-speed operation without thermal overload. A nominal speed of 2000 rpm fits production lines that require moderate velocity with high positional accuracy. Position data is sent through digital servo feedback (DSF), so the drive can correct errors during each control cycle. Precise mechanical fit is aided by a centering diameter of 130 mm, and the C-length stator section provides added winding length for higher thermal mass. The rotor uses a standard balancing grade to reduce vibration at operating speed, and the motor is supplied without a blocking brake, so holding force must be provided externally or by drive holding current when power is off.

Cabling exits on side A, and power plus feedback share a single connector interface, which helps keep routing compact. Using one connection point for both circuits also reduces the number of separate cable entries at the motor housing. A factory-installed shaft seal helps keep coolant spray and fine dust away from the bearings, while the motor uses the standard housing style of the series. The motor has a frame size of 112, so the mounting face and pilot register match other motors in this size class. The output element is a plain shaft that accepts shrink-fit couplings or clamping hubs. The shaft is present only on the drive end, which reduces overall length and can simplify enclosure layout where rear clearance is limited.
