MAC AC Servo Motors
Rated 4 stars (3 total reviews)
The MAC090C-0-GD-4-C/110-B-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts commanded currents into precise rotary motion for positioning axes and speed-regulated spindles in automated equipment. Integrated incremental and tacho feedback channels allow the external amplifier to monitor velocity and position in real time, making the unit a compact actuator for general-purpose industrial automation.
A centering flange dimension of 110 mm locates the housing accurately on machine faces, and heat is removed by natural convection so no auxiliary fan is required. The winding supports a nominal speed of 3000 rpm, giving the connected drive a broad velocity range before field weakening is needed. Environmental sealing reaches IP65, keeping dust and low-pressure water jets away from internal components. Motion feedback is produced by an incremental encoder (WI) that delivers 1250 lines per revolution and accepts edge rates to 300 kHz; its TTL (RS-422) outputs are powered from 5 V ± 5 %. Power conductors terminate on a connector at side B, while signal wiring shares the same axial direction, simplifying cable routing. The motor is supplied without a blocking brake, reducing inertial load and maintenance.
Operation is permitted up to 1000 m above sea level and at ambient temperatures not exceeding 45 °C. Winding code GD identifies the stator layout chosen for this frame size, and the standard tachogenerator supplies 3 V/1000 rpm to the drive for coarse speed feedback. Storage conditions range from −20 °C to +80 °C without risk to magnetic or insulation properties. Standard tacho quality and an incremental encoder with standard mounting are complemented by an option for absolute feedback per the stated configuration. All service cooling remains natural convection, and IP65 sealing is retained despite the absence of a blocking brake.
