HC-SF352K 3.5KW Mitsubishi Industrial Servo Motor HC SERIES

1. Product Description​​

The Mitsubishi HC-SF352K is a high-capacity, high-inertia AC servo motor designed for demanding industrial applications that require high torque and superior control over heavy loads. It is part of Mitsubishi's extensive HC-SF series, renowned for its robustness and performance.

This motor is engineered to work seamlessly with compatible Mitsubishi servo amplifiers (such as the MR-J4-350B or larger) to form a complete motion control system. Its key feature is a high-inertia rotor, which provides exceptional stability and reduces the impact of load fluctuations, making it ideal for applications with high moment-of-inertia loads. The motor ensures smooth rotation, even at low speeds, and offers excellent responsiveness for precise positioning and speed control. It is built to deliver reliable, maintenance-free operation in rigorous automation environments.
