Product Description:

The MAC90C-0-GD-1-B/110-A-0/J625/S01 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Built for analog drive systems, it converts commanded current into repeatable torque for axes that require precise speed or position regulation in industrial automation equipment. The motor uses natural convection for heat dissipation, allowing it to mount close to the load without external fans or liquid cooling. It is suited for packaging equipment, transfer axes, and other automated machinery that depends on consistent rotary motion.

During continuous operation, the unit delivers a nominal speed of 3000 rpm, which supports steady operation on servo axes that need a broad usable speed range. At zero shaft movement, it can maintain a holding torque of 9.6 Nm, enabling the axis to resist static loads without a mechanical brake. The phase windings draw 20.2 A under rated motion and up to 24.8 A when the shaft is locked, so the drive amplifier can apply appropriate running and stall current limits. The housing is rated IP65, which helps protect internal components from dust and water jets. The motor also uses a 110 mm centering diameter and a 24 mm shaft diameter for alignment with compatible machine interfaces.

In transient moves, the drive can command a peak pulse current of 196 A, giving the motor enough headroom to accelerate loads before thermal limits are reached. The housing weighs 23 kg, providing structural stiffness that supports the shaft during process vibration. Dynamic response is influenced by a rotor inertia of 53 × 10⁻⁴ kg·m², which affects acceleration behavior when the motor is matched with the connected load. Heat absorbed during such cycles dissipates over a thermal time constant of 60 min, and the winding data includes a torque constant of 0.43 Nm/A, an inductance of 1.5 mH, and a winding resistance of 0.24 Ω for compatible drive tuning.
