Product Description:

The MDD093B-N-020-N2M-110PB2 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it converts commanded current into precise rotary motion for positioning and velocity control in automated machinery. The B-length frame and 093 stator size provide the torque density needed for medium-duty feed drives in packaging cells, transfer stations, and metal-cutting equipment. Its standard housing dissipates heat through the mounting flange, and Grade G dynamic balancing helps keep vibration low during extended operation.

At standstill, the motor sustains a continuous torque of 14.5 Nm, permitting stable holding or slow-speed indexing without auxiliary cooling. During motion, it can reach a rated shaft speed of 2000 rpm. Electrical power and feedback exit on Side B, allowing cables to follow the machine wall through a single circular connector secured against vibration. Rotor position and revolution count are provided by an integrated multi-turn absolute encoder, so the control system has absolute position data immediately after power-up. For gravity-loaded axes, a blocking brake delivers 22 Nm of static torque to secure the load whenever drive power is removed.

Mechanical alignment is aided by a centering pilot diameter of 110 mm that mates with the mounting recess to limit radial runout. Loop closure relies on digital servo feedback (DSF), which sends high-resolution position data to the controller during each control cycle. The output shaft is machined with a keyway for positive drive to pulleys or couplings, and a dedicated shaft seal helps block coolant or oil from migrating along the shaft into the bearings. The aluminum housing provides a direct thermal path for internally generated heat. There is no secondary shaft end, so the rear of the motor remains reserved for the encoder and brake assembly.
