Product Description:

The MAC071B-0-FS-4-C/095-A-1/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current into controlled rotation for automated assembly stations, material-handling gantries, and packaging axes. This layout makes the motor suitable for precise start-stop motion as well as steady speed control in general automation equipment. Its mechanical interface follows the MAC series geometry, so it fits installations built for this frame format and standard flange-coupled axes.

The motor has size code 071, which indicates the frame used for the mounting footprint and available torque density. The winding designation FS sets the electrical layout used with the matching drive. A nominal speed of 2000 rpm suits analog drive regulators that generate standard reference frequencies. Accurate seating against the machine flange is provided by a centering diameter of 95 mm, which helps keep radial runout low at the coupling. When the axis must hold position during an emergency stop or power loss, the integral blocking brake applies 3 Nm of static torque to lock the shaft.

Heat generated in operation is removed through natural convection, which avoids the need for auxiliary fans or liquid cooling. For velocity regulation, the motor carries a combined feedback assembly: the drive receives real-time speed data from a tacho feedback unit, while incremental pulses report shaft position to the motion controller. The feedback arrangement lets the controller compare commanded motion with actual motor response during changing loads. The tachometer produces 3 V/1000 rpm, so the drive can monitor speed with minimal signal conditioning. All three power phases are routed through a connector on side A, allowing the cable bundle to exit toward the backplate and helping keep wiring clear of nearby moving machine parts.
