MAC025C-0-QS-4-E/040-A-1/WI652LV
MAC AC Servo Motors
The MAC025C-0-QS-4-E/040-A-1/WI652LV servo motor from Bosch Rexroth Indramat is a compact yet powerful member of the MAC AC Servo Motors series, engineered for demanding industrial automation environments. With a Nominal Motor Speed of 2000 min⁻¹ and a Continuous Torque At Standstill of 9.2 Nm (up to 12.0 Nm with surface cooling), this unit delivers responsive motion control for precision positioning tasks. The rotor’s inertia, rated at 22 × 10⁻⁴ kg·m², facilitates smooth acceleration and deceleration profiles, minimizing overshoot in dynamic applications. Weighing 13.0 kg, the motor balances a robust mechanical design with manageable mass for straightforward integration. A Torque Constant At 20 °C of 0.875 Nm/A and Continuous Current At Standstill of 11 A (up to 14 A with surface cooling) ensure consistent torque output across varying load conditions, supporting both high and low-torque requirements.
Performance optimization is achieved through finely tuned electrical characteristics: the Windings Resistance At 20 °C of 1.313 Ω and Windings Inductance of 16.0 mH limit harmonic distortion and enhance current response. The motor accommodates peak demands with a Maximum Peak Of Pulse Current of 54 A, enabling rapid torque bursts for acceleration phases. A standard Thermal Time Constant of 50 minutes (reduced to 30 minutes with enhanced cooling) maintains thermal stability under sustained operation. The Insulation Classification F rating safeguards winding integrity, while the IP65 Protection Category ensures resilience against dust ingress and low-pressure water jets. This combination of peak current capacity and thermal management supports continuous operation in high-load cycles without compromising system reliability.
Designed for seamless integration, the motor operates reliably within a Permissible Ambient Temperature range of 0 to +45 °C and survives transport and storage conditions from –20 to +80 °C. The robust construction and IP65 sealing make it ideal for applications in material handling, automated assembly, and robotics, where dust, moisture, and mechanical stress are prevalent. Bosch Rexroth Indramat’s one-year Warranty provides additional assurance of product durability and performance consistency. Industrial OEMs and system integrators will appreciate the MAC025C’s modular mounting interfaces and standardized electrical connections, which reduce installation time and streamline maintenance. As part of a comprehensive automation platform, this servo motor meets the rigorous demands of modern manufacturing and process control systems.
