Product Description:

The MAC063B-0-GS-4-C/095-B-0/WI520LV is an AC synchronous servo motor from Bosch Rexroth Indramat in the MAC AC Servo Motors series. Built for analog drives, the unit converts drive commands into controlled shaft rotation for packaging, assembly, and handling axes. Because it is intended for analog drive systems, the external amplifier handles the control loops while the motor supplies the electromechanical output and feedback signals needed for regulation. This makes the unit suitable for axes that require smooth acceleration, stable speed control, and repeatable stopping behavior during frequent cycles.

Nominal shaft speed is 3500 rpm, which gives the associated amplifier a high operating speed for velocity control. A 95 mm centering diameter positions the housing concentrically to couplings or gearbox faces for accurate alignment during mounting. Heat is removed by natural convection, so the installation should allow unobstructed ambient airflow rather than rely on forced cooling. The GS winding code identifies the electrical characteristics used with compatible MAC analog drives, and power reaches the stator through a connector on side B to support straightforward cable routing. That cable orientation can help keep lead routing close to the machine structure when the motor is mounted against a plate or connected to a compact drive train. The motor has no blocking brake, and its standard tacho quality suits general-purpose duty.

Motion feedback is provided by an integrated incremental encoder, which supplies position information to the drive for closed-loop control. The built-in tachogenerator outputs 1.5 V/1000 rpm, giving analog speed feedback for velocity regulators that use a tacho signal. Using both encoder feedback and a tachogenerator lets the motor support position monitoring and analog speed feedback within the same package. The mechanical envelope corresponds to motor length B and motor size 063, which helps the motor fit compact machine frames while keeping moving mass moderate. This layout supports accurate stopping and stable speed response during repetitive pick-and-place or feeder motion.
