Product Description:

The MAC063B-0-JS-4-CX095-A-1/WI520LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog servo amplifiers, the unit supplies precise rotary motion for positioning axes, tool spindles, and pick-and-place joints found in packaging, handling, and assembly machinery. It combines mounting features, a built-in tachogenerator, and position feedback so analog control loops can regulate speed and torque without separate external sensors during continuous machine operation and quick position changes. A standard blocking brake secures the shaft when power is removed, which is useful on vertical axes and indexing applications.

At its nominal speed of 6000 rpm, the motor delivers stable velocity that matches the frequency supplied by the drive, allowing synchronization with conveyor or spindle cycles across repeated machine cycles. The integrated blocking brake can hold 3 Nm of torque to limit drift while the axis is stopped. Shaft alignment is guided by a 95 mm centering diameter, which mates with machine flanges and helps keep radial runout within tolerance. Cooling relies on natural convection, so no fan or external coolant is required and the housing dissipates heat from rated operation. A built-in DC tachogenerator produces 1.5 V/1000 rpm, giving the analog speed loop a proportional feedback signal. Power conductors enter through a connector on side A, which can simplify cable routing when the motor is mounted face down or inside compact enclosures.

Position control is handled by an incremental encoder installed under the feedback cover, and its standard mounting helps keep radial bearing loads low while supplying the resolution needed by the drive. The motor belongs to frame size 063, and its B-length housing keeps the stack compact for machines with limited installation space. Winding code JS indicates the electrical characteristics used with compatible analog drives in the same series. This arrangement supports repeatable acceleration and steady speed regulation in medium-speed automation axes where responsive starts and stops are required.
