Product Description:

The MAC093B-0-JS-3-C/130-B-2/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it supplies controlled torque and speed to automated machine axes that rely on analog velocity or current commands from the drive controller. By integrating an internal tachogenerator and a second shaft end, the motor can return real-time speed data while also driving an auxiliary device such as a fan, encoder, or brake-release mechanism. This arrangement supports applications that need main axis motion and accessory drive capability from the same motor housing.

To secure stationary loads, the motor includes a heavy-duty blocking brake that can hold up to 14 Nm of counteracting torque, making it suitable for vertical axes or intermittent stopping duties. Alignment to the driven machine is handled by a centering pilot of 130 mm, which helps the shaft run concentrically with couplings and gear stages. The rotor is wound for a nominal speed of 3000 rpm, allowing it to match common command profiles without overspeeding. Heat generated during continuous operation is removed by natural convection, so no external blower or coolant circuit is required and the housing needs unobstructed airflow around it.

The motor uses frame size 093 and length code B. Its winding code is JS, which sets the phase resistance and current limits for the paired analog drive. Speed verification is provided through tacho feedback and a second shaft end, and the tachogenerator outputs 3 V/1000 rpm to give the controller a linear voltage reference across the usable speed range. Power enters the stator through a connector on side B, which can simplify cable routing when the motor is mounted close to machine walls. The tachogenerator is built to standard quality and provides adequate accuracy for general-purpose positioning tasks.
