Product Description:

The MAC093B-0-JS-2-C/130-B-2/S005 is a servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Classified as a motor for analog drives, it provides position and speed control for machine tools, packaging lines, and material-handling axes. In service, it converts commanded current into controlled rotary motion for acceleration, steady running, and repeatable stopping. The unit combines an electromagnetic rotor-stator assembly with integral feedback sensing so that an analog drive can regulate velocity accurately during operation.

Mechanical holding is provided by a heavy-duty blocking brake that can resist up to 14 Nm of shaft torque, helping prevent drift when power is removed. The flange incorporates a centering pilot of 130 mm, which aligns the motor with gearboxes or machine frames and helps maintain concentricity under load. Heat generated by copper losses is dissipated through natural convection, so no external fan or liquid circuit is required. This passive cooling arrangement keeps the housing free of auxiliary airflow hardware. Rotor speed feedback comes from an internal DC tacho generator, and the tacho feedback signal gives the drive an analog voltage proportional to motor speed. The motor uses size code 093 and length code B, while the tacho's standard quality grade is suitable for general motion tasks.

Rated operation reaches 3000 rpm, which suits common spindle and conveyor duties without overspeeding the tacho circuit. Power and feedback cabling exit through a connector on side B, which simplifies routing when the non-drive end faces the panel wall. This cable direction can help when the motor is mounted close to surrounding machine framing. The tacho produces a feedback signal of 3 V/1000 rpm, allowing the analog controller to scale motor speed across the working range. The motor uses the JS winding code, which matches the electrical characteristics expected by compatible MAC servo amplifiers.
