Product Description:

The MAC090C-0KD-4-C/110-B-1/WI522LV is a permanent-magnet AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it translates command voltages from legacy servo amplifiers into controlled shaft rotation used to position machinery axes in automated packaging, material handling, and assembly equipment. The built-in feedback system lets the connected amplifier monitor motion continuously and correct speed or position changes during operation. Its analog command structure also suits retrofit systems that still rely on established servo amplifier platforms.

At its operating point, the rotor maintains a speed of 2000 rpm. During continuous stall, the shaft can deliver 10.4 Nm while drawing 17.0 A, and these values indicate the thermal load the drive electronics must handle. The electromagnetic structure produces 0.68 Nm/A, and copper loss is influenced by a phase resistance of 0.60 Ω. A 3.6 mH inductance filters current ripple, helping the analog controller maintain smooth torque. Heat generated under these conditions leaves the housing through natural convection, and the 60-minute thermal time constant means winding temperature rises gradually under load. A centering diameter of 110 mm aligns the flange with gearboxes or fixtures, while 0.0053 kg·m² rotor inertia balances rapid acceleration with steady running.

For intermittent peaks, the amplifier can supply 125 A, allowing short bursts of high torque without demagnetizing the magnets. The housing is sealed to IP65, blocking dust and water jets from the stator, and the optical feedback unit provides an encoder resolution of 2500 lines for motion control. With a mass of 23 kg, the unit resists vibration and remains practical to mount on industrial equipment. A holding torque of 6.5 Nm secures the load when power is removed, and operation is permitted up to 1000 m elevation without derating. The analog interface eases integration with existing cabinets.
