Product Description:

The MAC063B-0-GS-2-C/095-A-1 is a brushless AC servo motor from Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts sinusoidal phase currents into controlled torque for indexing tables, small gantries, packaging stations, and other compact automation equipment. Its permanent-magnet rotor supports responsive acceleration and accurate motion when paired with a compatible drive amplifier. The motor has a length code of B, giving it a compact housing that fits inside narrow machine columns and other installations with limited axial space.

The internal brake clamps the shaft with a holding torque of 3 Nm, preventing vertical loads from drifting during power interruptions. The rotor operates at a nominal speed of 3500 rpm, making the motor suitable for moderate-inertia loads that require rapid repositioning. A flange centering pilot measuring 95 mm supports coaxial alignment with gear reducers, couplings, and machine mounting surfaces. Heat is dissipated through natural convection, eliminating the need for a cooling fan and helping keep acoustic output low. For velocity control, the built-in tachogenerator delivers 1.5 V/1000 rpm, providing the analog amplifier with a proportional speed signal throughout the operating range.

The GS winding pattern provides the electrical resistance and inductance required by the compatible drive’s current loop. The motor uses frame size 063, which provides a compact interface for planetary gearheads when an application requires greater output torque. Power is routed through a connector on side A, allowing cable trays to remain on the fixed side of the machine without requiring the lead to loop around the axis. Integrated tachometer feedback supplies real-time rotor speed information, enabling the drive to correct velocity deviations as the mechanical load changes. The brake is housed within the motor assembly, so no separate external holding module is required for securing a stationary axis.
