Product Description:

The MAC093B-0-OS-2-C/130-B-0/S005 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Supplied as a motor for analog drives, it converts commanded current into mechanical rotation for axis positioning and speed control within automated equipment. When paired with legacy analog amplifiers, it provides consistent torque and velocity regulation for material handling, printing, and other machinery that depends on precise motion without digital feedback loops.

The mechanical interface uses a centering diameter of 130 mm, which aligns the flange with the driven load and helps keep mounting concentric. Cooling is done through natural convection, so heat dissipates through the housing without fans and the installation should allow free airflow around the motor surface. During operation, the shaft reaches a nominal speed of 2000 rpm, a value that suits common gearbox ratios in mid-torque systems. Power feeds the stator through a connector on side B, which keeps cables away from the load face. The motor belongs to frame size 093, matching the housing envelope used for this stator diameter. Tacho feedback supplies the analog drive with a real-time velocity signal for closed-loop speed regulation.

The winding code is OS, which indicates the resistance and inductance used for this variant. A tachogenerator delivers 3 V/1000 rpm, and the signal uses the series' standard tacho quality for reliable speed data. The motor has build code B, which gives it a moderate axial length while keeping installation depth compact. The motor has no blocking brake, so the shaft can rotate freely when power is removed and any required holding force must come from an external lock or drive-applied torque. This arrangement suits applications that rely on analog speed feedback instead of an integrated digital encoder.
