MAC112C-0-HD-4-C/130-A-0/WI522LV

The Bosch Rexroth Indramat MAC112C-0-HD-4-C/130-A-0/WI522LV is a high-performance permanent magnet synchronous servo motor in the MAC AC Servo Motors series, designed for precise motion control in industrial automation. This brushless device employs electronic commutation and delivers rapid response characteristics required for dynamic positioning tasks. Its rugged construction and IP65 protection ensure reliable operation in environments exposed to dust and water ingress. With a nominal speed of 2000min-1, the unit balances speed and torque output to meet varied application demands. Intended for use with Rexroth’s DSC, KDS, or TDM drive controllers, this motor forms the core of a responsive servo system.

The MAC112C-0-HD-4-C/130-A-0/WI522LV features a continuous torque at standstill of 27Nm and supports a continuous current at standstill of 41A, providing sustained performance under load. The torque constant at 20°C of 0.73Nm/A and winding inductance of 2.5mH define its electromechanical characteristics, while the windings resistance at 20°C of 0.150Ohms ensures predictable thermal behavior. The motor’s mass of 48Kg contributes to system inertia considerations, and its motor size 112 with motor length C positions it between compact and heavy-duty classes. Cooling by natural convection eliminates the need for auxiliary fans, and the thermal time constant of 100min indicates its thermal response under continuous operation.

Operational features include integrated real-time protection via special winding thermo switches that monitor winding temperature and prevent overtemperature damage. Feedback is provided through either incremental or absolute encoder options, supplemented by a tacho feedback system for precise speed measurement. The absence of a blocking brake (Blocking brake: Absent) reduces mechanical complexity and maintenance points. Built to Protection Class IP65, the motor withstands harsh industrial conditions, while its low-inertia rotor supports high-frequency start-stop cycles and rapid acceleration. The servo motor’s nominal speed of 2000min-1 and continuous torque rating ensure consistent performance in demanding motion profiles.

System integration is streamlined with Bosch Rexroth Indramat drive controllers such as the DSC, KDS, and TDM series, offering seamless communication and parameterization. The inclusion of standardized mounting dimensions and electrical interfaces accelerates machine assembly and retrofit projects. Target applications include robotic manipulators, packaging machinery, transfer systems, and other automation solutions requiring dependable, maintenance-free operation under challenging environmental conditions. The MAC112C-0-HD-4-C/130-A-0/WI522LV meets the exacting specifications of modern industrial motion control systems.
