Product Description:

The MAC063B-0-JS-4-C/095-B-1/WI522LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Supplied as a motor for analog drives, it converts commanded current into controlled shaft motion for precise positioning in automated pick-and-place, packaging, or handling stations. This variant pairs a B-length stator with a size 063 frame to provide a compact footprint while still allowing the internal windings to reach rated speed under natural cooling. A factory-installed blocking brake provides holding capability when the drive is de-energized.

At its nominal operating point, the shaft rotates at 6000 rpm, which supports high-speed operation with suitable gear ratios and load inertia. The integrated brake can withstand a static load of 3 Nm, so vertical axes can remain locked when power is removed. Precision alignment during installation is aided by the centering collar machined to 95 mm in diameter, which helps minimize radial runout between the motor face and the driven machine. Heat generated by copper losses is dissipated through the housing by natural convection, eliminating the need for forced air or liquid cooling circuits in compact cabinets. Torque production comes from the JS winding, whose electrical values suit analog MAC drives and allow fast current changes during dynamic motion commands.

Mechanical power is transferred through a shaft with a DIN 6885 keyway, providing a standardized interface for pulleys or couplings. Power conductors reach the stator windings through a sealed connector on side B, enabling cable layouts that avoid moving machine parts. Speed feedback for the analog controller is delivered by a tacho generator rated at 1.5 V/1000 rpm, and an incremental encoder mounted in the standard location supplies position data for finer interpolation. The compact 063 frame supports high-speed, low-to-medium torque axes in light machining or assembly lines.
