Product Description:

The MAC063A-0-ES-4-C/095-A-0/WI518LV is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it receives current-controlled commands from drive amplifiers and converts them into regulated torque and speed. Within automated assembly cells and material-handling lines, the unit’s compact frame and direct-coupled output simplify mechanical layouts while providing the rapid response demanded for indexing, tracking, and low-inertia motion sequences.

The mechanical interface uses a centering diameter of 95 mm, enabling precise pilot seating against gearboxes or mounting flanges. Heat generated in the stator is removed through natural convection, so no external blower or liquid circuit is required. The shaft reaches a nominal speed of 3500 rpm, giving adequate headroom for velocity loops used in packaging spindles. Power is supplied through a plug located on a connector on side A, which keeps cable runs short when the motor is installed on right-hand machine faces. For analog velocity feedback, the integral tacho produces 1.5 V/1000 rpm, and this voltage is proportional to speed for direct use by legacy drive electronics. Additional characteristics in this envelope include motor length A and a standard tacho quality grade.

Position data is captured by an incremental encoder with standard mounting, allowing the same housing to support digital position loops when the application requires indexing accuracy beyond the tacho signal. Electrical behavior is set by winding code ES, which sets phase resistance and inductance to match the current ratings of MAC series analog drives. The unit belongs to frame size 063, a diameter class that balances magnetic torque with low rotor inertia for quick reversals. The motor has no blocking brake, so holding torque must be supplied by the drive or external mechanics during power-off conditions, and this configuration reduces weight and eliminates brake wiring.
