Product Description:

The MAC063B-0-JS-2-C/095-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed as a motor for analog drives, it accepts voltage-controlled commands from legacy servo amplifiers and converts them into proportional torque and speed for positioning tables, feeders, and spindle axes in factory automation. Its compact frame supports quick integration in machine tools and packaging lines. This type of motor is commonly used where smooth low-speed control and repeatable response are required from an analog servo system.

Beneath its housing, precise mechanical alignment is established by a centering pilot of 95 mm, allowing the flange to seat accurately against gearboxes or bearing blocks. Heat generated by copper losses is removed through natural convection, eliminating external blowers and simplifying enclosure layouts. Because cooling is passive, the motor can be installed without separate fan wiring or auxiliary airflow hardware. The rotor uses winding code JS, which indicates the motor’s resistance and inductance values used by standard MAC drives. Under rated excitation, the shaft reaches a nominal speed of 6000 rpm, giving a wide operating range for velocity-regulated applications. For closed-loop control, a tacho generator delivers 1.5 V/1000 rpm, enabling the analog amplifier to monitor actual speed. The power terminals are presented on a connector on side A.

The motor is supplied without a blocking brake, so motion hold must be provided by the drive or an external clamp when power is removed. The motor uses a 063 frame and short length B, making it suitable where axial space is limited. Speed information is returned through tachofeedback with standard quality, allowing analog velocity loops to operate without digital encoders. The simple feedback arrangement also fits older control cabinets built around tachometer-based speed regulation.
