MAC112C-0-KD-1-B/130-A-0/DI01250

The Bosch Rexroth Indramat MAC112C-0-KD-1-B/130-A-0/DI01250 is a precision permanent magnet servo motor in the MAC AC Servo Motors series, engineered for medium-torque automation tasks. This compact unit delivers a 28 Nm standstill torque with a maximum speed of 1500 rpm, combining robust mechanical design with efficient electromagnetic performance. The integrated incremental encoder provides high-resolution position feedback and the motor’s low rotor inertia ensures rapid acceleration and deceleration. With a rugged construction and reliable power connector on Side A, this motor meets demanding reliability requirements in industrial environments. It is particularly suited to applications requiring dynamic response and precise motion control.

This model's technical specifications reflect a carefully balanced design for performance and efficiency. The motor draws a nominal 31 Amperes current consumption and features a torque constant of 1 Nm per Ampere for predictable torque output. Position feedback is provided by an incremental encoder with 1,250 lines per rotation and the corresponding encoder type incremental ensures consistent commutation accuracy. The rotor inertia of 0.170x10^-4 kgm² minimizes load on the drive system, while the winding’s inductance of 4.5 mH and resistance of 0.37 ohms reduce electrical noise and thermal losses. Natural convection cooling supports continuous duty cycles without auxiliary fans or water cooling, simplifying system design.

Operational performance is reinforced by a built-in tacho feedback system that generates 3 volts at 1000 rpm, enabling closed-loop speed regulation and rapid fault detection. The motor’s low inertia and immediate torque response allow for swift adaptation to changing control inputs, while the robust permanent magnet construction maintains torque stability throughout the operating temperature range. A C-interface encoder coupling and optional non-equipped blocking brake provision further enhance safety and positional security during power loss or emergency stops. The overall design ensures minimal vibration and acoustic noise, making this motor ideal for precision indexing and high-cycle production processes.

System integration is streamlined for compatibility with Bosch Rexroth Indramat drives and controllers, facilitating fast commissioning and parameter tuning. The MAC112C-0-KD-1-B/130-A-0/DI01250 integrates seamlessly into packaging machines, CNC tooling, robotics assemblies, and automated inspection systems requiring tight positional accuracy and repeatability. Its form factor—determined by motor size 112 and motor length C—matches industry-standard mounting interfaces, enabling drop-in replacement or retrofit upgrades. Engineers targeting compact, high-efficiency motion systems will find this servo motor an effective solution for medium-torque applications requiring dependable performance and service longevity.
