MAC112A-0-ZD-4-C/130-B-0/WI561BX

The Bosch Rexroth Indramat MAC112A-0-ZD-4-C/130-B-0/WI561BX is a high-performance AC servo motor in the MAC AC Servo Motors series, engineered for precision motion control in demanding industrial environments. This MAC Permanent Magnet Motor delivers reliable continuous torque and instantaneous current capabilities due to its robust design and integrated incremental encoder with standard mounting. The motor is configured with a power connector on Side B, optimizing cable routing in compact machine architectures. With a not-equipped blocking brake, the motor relies on controlled deceleration through natural convection cooling and advanced windings design to maintain stability during dynamic operations. Its overall architecture balances power density and ease of integration, making it suitable for automation, robotics, and packaging systems.

Detailed technical attributes of the MAC112A-0-ZD-4-C/130-B-0/WI561BX include a continuous torque at standstill of 10.7 (13.0) Nm and a corresponding continuous current at standstill of 14.5 (17.2) Amperes enabling sustained loads under peak demand. The motor achieves a nominal motor speed of 1500 min-1 and supports a maximum peak of pulse current up to 54 Amperes for rapid acceleration phases. A torque constant at 20 °C of 0.820 Nm/A and a windings inductance of 10.0 mH provide predictable dynamic response, while the windings resistance at 20 °C of 0.990 Ohm ensures thermal efficiency. Mechanical inertia is defined by a rotor moment of inertia of 61 x 10^-4 kg·m², facilitating precise velocity control. The motor’s mass of 25 kg and thermal time constant of 100 (75) min reflect a design optimized for long-term stability and heat dissipation via natural convection cooling.

Operational performance is characterized by smooth torque delivery and enhanced repeatability under varied load profiles. The natural convection cooling type maintains winding temperature without auxiliary fans, preserving system cleanliness and reducing maintenance. The incremental encoder provides high-resolution feedback, enabling closed-loop control with minimal positioning error. Configurable output options include power connection on Side B and feedback connector orientations in straight or angled formats for installation flexibility. Multiple output directions—Side A, Side B, left, and right—permit adaptation to diverse machine layouts while preserving the MAC112A series form factor.

System integration is streamlined through compatibility with common servo drives supporting the MAC AC Servo Motors series, providing real-time current and velocity regulation. The absence of a blocking brake simplifies the mechanical interface, relying on drive-based holding functions during standstill. Target applications encompass industrial robotics, CNC auxiliary axes, pick-and-place systems, and automated packaging lines where precise velocity control and rapid dynamic response are critical. The Bosch Rexroth Indramat MAC112A-0-ZD-4-C/130-B-0/WI561BX offers a balanced combination of torque density, thermal robustness, and installation versatility for modern automation challenges.
