Product Description:

The MAC063B-0-JS-4-C/095-B-0/WI517LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, the unit converts commanded current into controlled rotary motion for positioning, indexing, and speed-regulated tasks on automated machinery. Its mechanical frame follows the family envelope, so it can be installed in existing mounts without changes to coupling hardware. This makes it suitable for packaging equipment, indexing stations, and other machinery that depend on smooth low-speed regulation as well as rapid response to setpoint changes.

The motor’s centering pilot measures 95 mm, which helps align the housing accurately on a machine plate or gearbox face. Cooling relies on natural convection, so no external fan is required and surrounding air must carry away the heat produced during operation. The JS winding gives the electrical characteristics needed for a nominal speed of 6000 min⁻¹ with a compatible analog amplifier. This unit uses frame size 063, which keeps the shaft height and flange geometry consistent with other motors in the same series. Because cooling is passive, the motor can be used where a simpler external airflow arrangement is preferred.

Rotor position and velocity feedback are provided through integrated feedback channels. The tachometer delivers 1.5 V/1000 min⁻¹, a signal level suited to closed-loop speed regulation. Mains conductors connect through a power connector on side B, which helps keep cabling clear of moving elements at the front of the machine. The motor body uses length code B for a longer active stack, and position feedback is supplied by an incremental encoder. The combined feedback arrangement lets the paired analog drive monitor shaft motion during acceleration, steady running, and deceleration. The motor has no blocking brake, so holding force must be provided externally when the axis is at rest.
