Product Description:

The MAC090B-2-JD-4-C/100-A-1/WI520LX is an AC servo motor manufactured by Bosch Rexroth Indramat for incorporation into mid-range positioning axes that still use analog control loops. As a member of the MAC AC Servo Motors series, the unit supplies continuously regulated torque to spindles, transfer slides, and pick-and-place heads used in industrial automation. It translates drive amplifier commands into rotary motion, which helps maintain repeatable movement on machines that depend on stable speed regulation and accurate axis positioning.

The motor uses axial surface cooling, and an external blower rated at AC 115 V moves air along the housing fins to carry away internally generated heat. A standard blocking brake holds vertical loads when the drive is disabled, which helps prevent unintended movement at standstill. Power conductors and protective earth connect through a connector on side A, a layout that simplifies cable entry where space is limited around the motor body. Rotor position is returned to the drive by an incremental encoder with standard mounting, and the tachogenerator supplies velocity feedback so the control loop can monitor both speed and position during operation.

Application compatibility is increased because the unit is a motor for analog drives, so it works with ±10 V command signals and returns tacho voltage for legacy controllers. The feedback channel can also be configured as an incremental or absolute encoder with tacho feedback, which supports installations that require finer position evaluation while keeping the same general motor format. The compact frame and cooling arrangement allow multiple axes to be mounted side by side on shared machine plates without requiring separate fan hardware at each axis. This layout is useful in retrofit equipment where analog control architecture remains in service.
