Product Description:

The MAC90C-0-GD-2-C/130-B-1/S03 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Developed for analog drive controllers, it translates current commands into regulated torque and velocity, providing closed-loop motion for pick-and-place axes, indexing tables, and packaging machinery. A permanent-magnet rotor supports responsive acceleration and electronic commutation during repeated motion cycles.

The motor operates at a nominal speed of 3000 rpm. At standstill, it supplies a continuous torque of 9.6 Nm while drawing 24.8 A. For short acceleration bursts, the controller may demand up to 196 A of peak pulse current. The enclosure is rated IP65, protecting internal components from dust and water jets. Rotor inertia is 53 × 10⁻⁴ kg·m², and the unit weighs 23 kg, values that assist with axis sizing and mounting support calculations. Electrical response is governed by a phase inductance of 1.5 mH and a winding resistance of 0.24 Ω, which affect current rise time and electrical losses. A tacho generator delivers 3 V per 1000 rpm for analog speed feedback. The 60-minute thermal time constant indicates how gradually the windings heat under sustained load.

The spring-applied brake holds the shaft with 6.5 Nm of torque, clamps within 20 ms after power is removed, and releases within 60 ms when energized. This quick clamping action helps prevent vertical loads from drifting when electrical power is unavailable. The release interval allows the controller to coordinate brake disengagement with motor torque before motion begins. A torque constant of 0.43 Nm/A allows the analog amplifier to convert commanded current into predictable motor torque. The motor’s low phase inductance supports rapid current regulation during acceleration and deceleration. Its rotor inertia assists with drive tuning for stable velocity and position control in repetitive machine cycles.
