Product Description:

The MAC063B-0-GS-4-C/095-B-0/WI520LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts current commands from legacy controllers into precise rotary motion for machine tools, pick-and-place axes, and other automated stations. The unit occupies the 063 frame size within the platform, giving machine builders a compact option that supports closed-loop positioning and speed control in industrial automation applications.

A centering diameter of 95 mm aligns the housing with gearboxes or mounting flanges, while length code B keeps the overall depth modest for restricted spaces. Heat leaves the stator through natural convection, so no external fan or liquid cooling circuit is necessary. During continuous duty, the rotor reaches a nominal speed of 3500 rpm, supporting moderate feed rates with light to medium loads. Torque is transferred through a DIN 6885 keyway machined into the shaft, providing positive engagement with a compatible coupling. Because the motor has no blocking brake, any requirement to hold its position at standstill must be met by the drive or an external mechanical clamp. Standard tacho quality provides repeatable velocity signals for stable process control.

Signal integration relies on an incremental encoder mounted in the standard position to provide the controller with motion feedback. The tachogenerator delivers 1.5 V/1000 rpm, giving the analog controller a linear speed reference across the operating range. Power conductors exit through a connector on side B, simplifying right-hand cable routing inside tight enclosures. The coil layout uses the GS winding scheme, which matches the voltage and current profile of compatible Rexroth analog drive modules. The encoder and tachogenerator support closed-loop operation by supplying the position and velocity information required for accurate motor regulation. Cable placement on side B also helps keep the conductors clear of the shaft coupling and adjacent machine components.
