MAC AC Servo Motors
The Bosch Rexroth Indramat MAC112B-0-GD-4-C/130-A-2/WA606XX/S018 from the MAC AC Servo Motors series is a MAC Permanent Magnet Motor engineered for precision and high dynamics. It delivers a nominal motor speed of 3000 min^-1 while maintaining a compact motor size 112 and motor length B footprint. The motor relies on natural convection cooling to dissipate heat efficiently and features a rotor moment of inertia of 120 x 10^-4 Kgm^2 for rapid acceleration and deceleration. Its torque constant at 20 degrees C of 0.430 Nm/A ensures predictable torque output across a wide operating range.
Performance-wise, this AC servo motor provides a continuous current at standstill of 41 (75)^5) A and a continuous torque at standstill of 16 (29)^5) Nm for reliable low-speed holding. It tolerates a maximum peak of pulse current of 223 A for short bursts of high torque demand and features a thermal time constant of 90 (60)^5) min to manage thermal loads under cyclic workloads. The windings inductance of 1.2 mH and windings resistance at 20 degrees C of 0.090 ohm combine to deliver smooth current control and minimal electrical losses. With a mass of 36 kg, the motor balances inertia with compactness for high-density machine integration.
Equipped with a built-in B encoder and tachofeedback, this servo motor provides high-resolution position feedback and closed-loop accuracy. A heavy-duty blocking brake mounted on Side A doubles as a fail-safe device, ensuring safe shaft locking during power loss or emergency stops. Its configuration is ideal for CNC machines, robotics, and precision automation applications requiring frequent starts, stops, and exact positioning.
