Product Description:

The MAC112D-0-HD-4-C/130-B-0/WI522LX is an AC servo motor from Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. Designed for analog drive systems, this motor converts electrical command signals into controlled mechanical motion for positioning, conveying, and coordinated axis duties in automated machinery. Its electromechanical construction combines the rotor, stator, and feedback hardware in one housing, which helps the motor fit directly into compact machine layouts. This arrangement supports precise motion control without requiring separate feedback assemblies or additional coupling hardware for many direct-drive style installations.

Its flange aligns through a 130 mm centering diameter, providing repeatable registration against mounting plates. Heat is removed by natural convection, so no external blower or liquid circuit is needed. The stator uses winding code HD, which sets the torque constant and thermal behavior for this frame. Rated operation occurs at 1500 rpm, allowing the axis to synchronize with standard 50 Hz or 60 Hz process equipment. The motor is supplied without a blocking brake, so applications that require static holding torque must rely on drive energization or an external mechanical latch.

The integrated tacho generator outputs 3 V/1000 rpm, which the analog controller uses for closed-loop speed regulation. Position data comes from a factory-mounted incremental encoder, providing fine feedback resolution without additional adapters. Housing proportions correspond to size 112 with length code D, giving a practical balance between rotor inertia and continuous power capability. Power conductors connect through a plug on side B, which permits cable routing along the machine's non-drive face and can improve access around the mounting area. The combination of tacho and encoder feedback supports retrofit or multi-vendor drive environments that still use analog velocity loops.
