MAC AC Servo Motors
The Bosch Rexroth Indramat MAC112C-0-HD-4-C/180-B-0/WA612XX/S011 is a high-performance unit in the MAC AC Servo Motors series by Bosch Rexroth Indramat. This MAC Permanent Magnet Motor provides a continuous torque of 27.0 Nm at a standstill and sustains a continuous current of 41 A, ensuring reliable output under load. With a nominal motor speed of 2000 min^-1, it is engineered for precise motion control in applications such as conveyor systems, pumps, and general automation where accurate speed regulation and positioning are critical.
The motor’s technical profile includes a torque constant of 0.730 Nm/A at 20 °C, enabling efficient conversion of electrical energy into mechanical torque. Its rotor moment of inertia of 170 x 10^-4 Kgm^2 offers a balanced dynamic response, while the maximum peak of pulse current reaches 195 A for brief high-load demands. Winding inductance is rated at 2.5 mH, and the winding resistance at 20 °C is 0.150 ohm, characteristics that optimize current flow and thermal stability. This model features natural convection cooling, eliminating the need for auxiliary cooling fans and reducing maintenance complexity. The motor mass is 48 kg, reflecting a robust construction that supports long operational life.
Designed for flexible integration, the MAC112C-0-HD-4-C/180-B-0/WA612XX/S011 incorporates a Side B power connector and a C-type encoder, facilitating compact installation and simplified wiring in confined spaces. Notably, it is Not Equipped with a holding brake, reducing weight and improving electrical efficiency by eliminating brake power draw. The absence of a brake component minimizes routine servicing and wear points. Its thermal time constant of 100 min ensures slow, controlled temperature rise under continuous operation, enhancing durability. In industrial settings, this servo motor delivers smooth acceleration, precise positioning, and low maintenance, making it an ideal choice for applications where efficiency, reliability, and longevity are paramount.
