MAC AC Servo Motors
The Bosch Rexroth Indramat MAC112B-0-GD-4-C/130-B-2/WI520LV/S048 from the MAC AC Servo Motors series is a robust AC Servo Motor engineered for precision industrial automation. This MAC112B-0-GD-4-C/130-B-2/WI520LV/S048 delivers a continuous current at standstill of 41 A and a continuous torque at standstill of 16 Nm, ensuring reliable start-up performance under load. Built on a Motor Size 112 frame with a Motor Length B, the motor employs Natural Convection cooling for silent, maintenance-free operation. Insulated to class F, it maintains winding integrity across prolonged duty cycles.
Mechanically, the motor incorporates a heavy duty holding brake rated at 60 Nm torque, providing positive load retention when deenergized. With a total mass of 39.5 kg, including a 3.5 kg brake assembly, it balances inertia and payload for stable motion control. The torque constant of 0.43 Nm/A and winding resistance of 0.09 ohm yield predictable torque output and low I²R losses. Thermal management is characterized by a thermal time constant of 90 min, allowing gradual heat buildup and ample cooling intervals.
Feedback and installation flexibility are delivered via an incremental encoder with tachofeedback, offering 1.5 V per 1000 RPM below 3000 RPM and 3 V per 1000 RPM above, matching the motor’s 3000 RPM nominal speed. A centering diameter of 130 mm accommodates both B05 and B14 flange types, and the power connector on side B simplifies cabinet integration. Rated for storage temperatures from minus 20 to 80 °C, this IP65-protected motor thrives in harsh environments, making it an ideal choice for demanding servo applications.
