MAC090C-0-KD-4-C/110-A-0/WI518LV/S001

The Bosch Rexroth Indramat MAC090C-0-KD-4-C/110-A-0/WI518LV/S001 from the MAC AC Servo Motors series is engineered for precision motion tasks requiring high reliability. Featuring a Motor Size 90 frame and Motor Length C, this AC servomotor delivers a nominal speed of 2000 min-1 and handles a phase current of 13.9 A for sustained performance. The unit employs Natural Convection as its Cooling Mode and integrates Tacho Feedback along with primary Tacho feedback for accurate speed monitoring. The compact design conforms to the standard Pilot Diameter Type, ensuring compatibility with industry mounts.

Built with a completely closed housing per DIN 40 050, the MAC090C supports a keyed output shaft sealed by a Shaft Sealing Ring that prevents ingress and allows form-fitting shaft-hub connections without additional adapters. Bearings are greased for life, eliminating maintenance intervals, and the absence of a blower connection underscores the reliance on natural convection cooling. There is No Second Shaft End, streamlining installation where a single output interface suffices. The built-in incremental encoder uses standard mounting, provides high-resolution tacho signals, and is not affected by water jets or condensate.

Installation and operation protocols emphasize care: the device includes No Holding Brake, and power cable connections are optimized for soldering with inch-diameter conductors or the manufacturer’s ready-made cables. Harsh cleaning agents must be avoided, and the motor must not be tipped or dropped during transport. When run at approximately 100 rpm for the initial grind-in sequence, the drive controller should be closed after one minute to protect the winding type KD. Under elevated thermal load, the housing may shift by up to 0.6 mm, so clearance and mounting rigidity are critical design considerations.
