Product Description:

The MAC090C-0-GD-4-C/110-B-1/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. It is intended for integration with analog velocity or position controllers, where it translates amplifier output into controlled shaft motion for machine tools, pick-and-place axes, and general handling equipment. The motor uses the 090 frame class within the series, and its C-length housing gives it a larger active section than shorter units in the same frame size. It is built for continuous industrial duty while relying on surface cooling alone. This arrangement makes it suitable for machines that still use external analog amplifiers rather than fully digital servo platforms.

Electrical behavior is set by the winding code GD, which gives the paired drive a known current-to-torque relationship. A centering shoulder of 110 mm aligns the flange during installation and helps maintain concentricity under load. Heat leaves the housing through natural convection, so no fan or liquid lines are fitted. Because cooling is passive, the surrounding installation space should allow heat to rise freely around the motor surface. Power conductors enter through a connector on side B, which helps keep cable runs clear of moving carriage parts. When power is removed, the integrated blocking brake holds the shaft to support vertical or suspended loads.

The feedback assembly includes tachogenerator output for velocity control together with an incremental encoder for position capture, giving the analog drive both speed and angle information through one interface. Motion smoothness benefits from the motor's standard tacho quality, which keeps ripple low enough for precision feed tasks. Supplied as a motor for analog drives, it works with legacy control platforms that use analog command signals and proportional tacho feedback. The tacho signal supports velocity regulation, while the encoder supplies position data to the external controller. That combination lets older analog systems separate speed feedback from position monitoring without adding a second feedback device.
