Product Description:

The MAC093B-0-GS-4-C/110-A-2/AM164SG is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drives, it converts continuous control voltages into regulated mechanical output for industrial automation equipment. The size 093 frame and B-length stator provide a compact footprint while maintaining enough magnetic volume for moderate continuous loads. This configuration allows pairing with legacy Indramat drive amplifiers to move packaging, printing, and material-handling axes that require accurate positioning and repeatable velocity.

The mechanical interface uses a 110 mm centering diameter that seats the flange squarely against reducers or machine plates. When energized at rated voltage, the rotor spins to 4000 rpm, giving sufficient headroom for fast indexing cycles. Heat is removed by natural convection, eliminating the need for blowers and reducing maintenance points. Power enters through a connector on side A, so cables stay clear of moving parts. A heavy-duty blocking brake inside the housing clamps the shaft with 14 Nm of static torque, allowing vertical axes to hold a load without external clamps. The brake supports load holding when power is removed, while the motor’s standard tachogenerator provides speed feedback.

The motor uses an absolute encoder, which delivers unique position values after every power-up. Incremental tacho feedback is also available when tighter velocity loops are required. The tachogenerator produces 1.5 V/1000 rpm, a level the analog amplifier scales directly into its regulation circuits, and its standard tacho quality classification indicates consistent ripple performance. Inside the stator, winding code GS identifies the resistance and inductance values used by the drive for current limiting and field weakening.
