Product Description:

The MAC063B-0-RS-4-C/095-B-0/WA612XX/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as the prime mover on precision axes that are regulated by analog velocity or current loops, supplying controlled torque and speed to automated assembly, packaging, and material-handling equipment. The unit is suited for applications that need repeatable starts, stops, and stable speed regulation within closed-loop motion systems.

A centering diameter of 95 mm positions the housing accurately against the mounting surface, limiting radial runout during high-speed operation. Heat is removed through natural convection, so no external blower or liquid circuit is required in standard duty cycles. With a frame size coded 063, the motor maintains a compact footprint while delivering the torque range expected from this series. The electromagnetic design uses winding code RS, which indicates the resistance and inductance values matched to Indramat analog drives. Power is transferred to the load through a shaft machined with a DIN 6885 keyway, allowing direct coupling to timing pulleys or spur gears without additional machining.

No blocking brake is fitted, so static holding torque must be provided by external mechanics or continuous drive current. Speed feedback is rated with standard tacho quality, and an attachment set for position feedback allows later encoder integration if required. Incoming power is routed through a connector on side B, simplifying cable runs inside tight enclosures. Classified as a motor for analog drives, it interfaces directly with transconductance amplifiers that output a proportional current signal. The mechanical length designation B keeps rotor inertia low for rapid acceleration, and motion control schemes can use tacho feedback, an incremental encoder, or an absolute encoder to obtain velocity or position data.
