Product Description:

The MAC063C-0-MS-4-C/095 is a permanent-magnet AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a compact motion element, it couples to analog servo drives to translate electrical command signals into rotary motion with positional accuracy suited to automated axes. In industrial automation, the motor actuates machine-tool spindles, packaging stations, and pick-and-place modules where closed-loop speed and torque control are required, while the housing and shaft interface follow standard MAC geometry for compatible machine layouts.

The motor sits in the 063 frame class, giving it an external diameter compatible with moderate-power axes while keeping mass low. Its construction corresponds to the C length code, so the active stack is extended enough to develop continuous torque without enlarging the flange footprint. A centering recess of 95 mm ensures concentric alignment on the mounting surface and helps maintain runout limits when coupled to precision gearboxes. Rated speed reaches 3500 rpm, allowing direct connection to fast-moving loads without overspeeding the feedback devices. Heat generated in the stator is released to ambient air through natural convection, eliminating the need for forced cooling hardware and reducing maintenance.

Signal resolution and commutation accuracy are provided by the programmable feedback stage; the unit can be supplied with tacho feedback, incremental encoder, or absolute encoder interfaces, permitting direct speed or position loops in legacy control topologies. Its stator wiring follows the MS winding code, matching phase impedance and voltage constants used in MAC drives of the same power class. For velocity monitoring, the built-in tacho generator outputs 1.5 V per 1000 rpm, and its quality grade is standard for closed-loop smoothness in medium-precision axes. Categorized as a motor for analog drives, the model supports earlier controller generations without additional interface converters.
