Product Description:

The MAC063A-0-ES-4-C/095-B-0/WI524LV is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Delivered as a motor for analog drives, it pairs with external velocity and current controllers. These controllers convert electrical commands into tightly regulated shaft rotation for assembly stations, pick-and-place axes, and compact machine tools. The motor’s integrated feedback components provide the signals needed to regulate motion under changing loads and during repeated positioning cycles.

The motor uses winding code ES, providing electrical parameters that match low-voltage analog amplifiers while maintaining a rapid current rise. A frame designation of 063 indicates the stator cross-section, and the centering diameter of 95 mm provides accurate pilot seating on gearbox or flange adapters. Its nominal speed of 3500 rpm supports high-throughput positioning, while the motor length of A keeps axial depth minimal in confined installations. Heat is dissipated by natural convection, eliminating forced-air hardware and simplifying enclosure design. The feedback configuration supports tacho feedback together with incremental or absolute encoders, allowing both speed and position loops to operate from one feedback stack. Standard tacho quality provides consistent voltage linearity across the operating speed range.

Power conductors exit through a connector on side B, which keeps service access on the drive-away face of a machine and shortens cable runs to rear-mounted amplifiers. The integrated tachogenerator produces 1.5 V/1000 rpm, a level directly accepted by classic analog velocity cards. Rotor angle is reported by an incremental encoder mounted in the standard interface housing, allowing connection to compatible position controllers without adapter plates. The motor has no blocking brake, so vertical loads must be held by an external mechanism or drive torque when power is removed. This brake arrangement also requires the machine design to account for load retention during shutdowns or drive faults. Cable routing should preserve access to the side-B connector and avoid placing excessive strain on the power conductors.
