Product Description:

The MAC090C-0-GD-4-C/110-B-0/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It functions as the rotary element in industrial automation axes, where commanded current from a drive amplifier produces controlled torque and velocity. Installed in machine tools, packaging lines, and pick-and-place gantries, the unit supports precise positioning and repetitive motion sequences required in automated production.

It has a centering land of 110 mm, allowing the motor flange to align concentrically with gearboxes or mounting plates and minimize radial runout. Thermal dissipation relies on natural convection, so no auxiliary fan or liquid circuit is required and installation space remains compact. The power conductors terminate through a connector on side B, which keeps cabling away from the driven shaft and simplifies access. As a motor for analog drives, its electrical characteristics are matched to legacy Indramat transistor amplifiers that use ±10 V command signals. Inside the stator, the GD winding code identifies the wire gauge and turns per phase, which affect the voltage constant and continuous torque rating.

For holding requirements, the motor is supplied without a blocking brake, so load retention during power-off must be handled by external mechanisms or continuous motor torque. Speed feedback can be provided by tacho feedback, an incremental encoder, or an absolute encoder, depending on the configuration used with the drive. Position information is delivered through an incremental encoder with standard mounting, giving differential TTL or sinusoidal signals compatible with conventional controller interfaces. The sensing circuitry uses standard tacho quality, which provides predictable linearity and phase shift for accurate regulation when the axis accelerates, decelerates, or reverses direction.
