Product Description:

The MAC09C-0-KD-3-C/110-B-1/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts controlled current into precise rotary motion for positioning and feed axes in automated equipment. Its integrated permanent-magnet design supports rapid response in industrial automation tasks. The motor is suited to axes that need steady speed control and repeatable stopping behavior during normal machine cycles.

At standstill, the motor delivers a continuous torque of 10.4 Nm while drawing a steady current of 17.0 A. This operating point reflects the continuous thermal load at zero speed. The electromagnetic conversion factor is a 0.68 Nm/A torque constant, so the motor produces proportional torque for each ampere commanded by the analog drive. Under rated conditions, the shaft reaches a nominal speed of 2000 rpm, and acceleration is influenced by the rotor inertia of 53 × 10⁻⁴ kg·m². Electrical parameters include 3.6 mH phase inductance and 0.60 Ω winding resistance, which affect current rise time and the voltage needed during speed changes. The 60-minute thermal time constant allows moderate load peaks without immediate overheating.

For dynamic transients, the drive can command a peak pulse current of 125 A, enabling short bursts of acceleration beyond the continuous rating. When power is removed, the integrated brake supplies 6.5 Nm of holding torque and engages within 20 ms. Brake release requires 60 ms once the control coil is energized by a 0.7 A holding-brake current. Mechanical mounting is supported by a 110 mm centering diameter, and the complete assembly weighs 23 kg, which is important in vertical-axis or gantry installations. The housing has an IP 65 protection rating, so dust and low-pressure water jets do not interfere with operation.
