Product Description:

The MAC063B-0-JS-1-C/095-B-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it converts electrical commands into precise rotary motion for positioning or velocity control in automated machinery, packaging lines, and similar industrial equipment. It forms part of closed-loop motion axes that depend on continuous voltage and current references rather than fieldbus-based commands. Its construction combines a compact rotor, encoder, and integrated brake so that a single assembly can both generate and hold torque during fast, repeatable moves.

The mechanical interface centers on a 95 mm location bore that aligns the housing with the driven machine frame. Frame designation 063 indicates the stator diameter, and the B length code extends the active stack to raise torque without increasing diameter. Under rated excitation, the shaft can reach 6000 rpm, a speed suited for rapid indexing tasks while remaining within bearing limits. Thermal energy is removed by natural convection, eliminating the need for forced-air accessories in compact cabinets. The blocking brake can apply 3 Nm of holding torque to keep loads stationary when power is removed.

Position and velocity information return to the analog drive through incremental encoder feedback, allowing the controller to correct any deviation during each cycle. Power is routed through a connector on side B, which simplifies cable runs when the motor is mounted with the shaft facing forward. For velocity estimation independent of the encoder, an internal tacho generator produces 1.5 V/1000 rpm with standard linearity, and its quality grade is standard. Winding code JS balances current demand and back EMF, keeping the motor compatible with compact slide or spindle assemblies.
