Product Description:

The Bosch Rexroth Indramat MAC063B-0-GS-2-C/095-B-0/S001 is a compact servo unit within the MAC AC Servo Motors series. Designed as a drive element for analog control loops, it converts electrical commands into precise rotary motion required by pick-and-place stations, indexing tables, and similar industrial axes. It is intended for legacy MAC systems that use established mechanical and electrical interfaces for analog servo operation. Its compact format suits machine layouts where accurate speed control and repeatable positioning are needed in limited installation space.

A centering pilot of 95 mm aligns the housing with machine frames, while the standardized motor size 063 keeps the flange pattern uniform across this diameter class. The motor length B housing provides additional stack height for higher torque without changing the mounting footprint. Heat is removed through natural convection, so no external blower or liquid lines are necessary. Clear airflow around the frame helps maintain operating temperature during typical duty cycles. During operation, the rotor reaches 3500 min⁻¹, a nominal speed suited to medium-speed transfer mechanisms and lightly damped drive trains.

Motion is monitored by a resolver-based circuit that also provides tachometer feedback, allowing analog velocity loops to sense real-time shaft speed. The tachogenerator outputs 1.5 V/1000 min⁻¹, providing a voltage proportional to speed for straightforward use with legacy drive cards. Power conductors exit through a connector on side B, which helps keep cables clear of gearboxes mounted on the opposite end. The winding code GS identifies the electrical winding so the drive can use the correct current limits and pole-pair data. Because the unit is supplied without a blocking brake, external holding must be used when power is removed.
