Product Description:

The MAC093B-0-JS-4-C/130-B-1/WA612XX/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a motor for analog drives, it interfaces with legacy drive amplifiers that output continuous current rather than sampled signals. In automated plant cells, the unit provides the closed-loop shaft rotation needed for positioning tables, feed rollers, and pick-and-place heads, translating controller commands into repeatable mechanical motion while maintaining velocity accuracy under changing load.

A standard blocking brake is integrated to hold vertical axes when power is removed. The stator housing has a 130 mm centering diameter that seats accurately in precision mounting flanges, and the JS winding code indicates resistance and inductance matched to mid-range analog amplifiers used on legacy equipment. Rotor speed is rated at 3000 rpm for nominal duty, which suits many spindle and axis applications. Heat is removed through natural convection, so no separate blower or coolant circuit is required. The motor has length B, and the power connector is oriented toward side B, which can simplify cable routing when that side faces the machine enclosure.

Position sensing relies on an incremental or absolute encoder with tacho feedback mounted through the supplied attachment set, allowing the drive to close speed loops without an external sensor. This feedback arrangement gives the amplifier continuous motion information during operation and supports stable speed regulation in analog control systems. Shaft torque is transmitted through a DIN 6885 keyway, and the housing uses the compact size 093 frame code for compatibility with existing MAC gearheads. For drive calibration, the built-in tacho generator provides 3 V per 1000 rpm, and its standard signal quality is suitable for most velocity control tasks.
