MITSUBISHI JAPAN AC Servo Motor HG-SR202 150V HGSR202 3AC 2000 RPM #3 G21012004
The Mitsubishi HG-SR202 is a high-performance, medium-inertia AC servo motor designed for industrial automation applications requiring precise motion control, high torque, and reliability. It is part of Mitsubishi’s HG-SR series, renowned for its robust construction and compatibility with Mitsubishi’s MR-J4 and other servo amplifier series.
Overall Description:
This motor is engineered for applications where dynamic response and consistent torque over a wide speed range are critical. Its medium-inertia design makes it ideal for machines that need both high torque for acceleration and smooth operation, such as indexing tables, conveyor drives, and material handling systems.
Key Features & Benefits
-
High Performance:Â Offers excellent responsiveness and high torque for rapid acceleration and deceleration.
-
Medium Inertia:Â Strikes a balance between high-inertia (for stability under varying loads) and low-inertia (for rapid acceleration) motors, making it versatile for a wide range of applications.
-
High Resolution Encoder:Â Features a high-resolution absolute encoder (typically 24-bit, or over 16 million pulses/revolution) providing extreme positional accuracy and eliminating the need for a homing routine after a power cycle.
-
Robust Construction:Â Built with a high-quality IP65 rating (splash-proof and dust-tight), making it suitable for harsh industrial environments.
-
Smooth Operation:Â Advanced magnetic design minimizes torque ripple, ensuring very smooth rotation even at low speeds.
-
Integrated Brake:Â The designation often includes a “BJ” suffix (e.g., HG-SR202BJ) if an electromagnetic brake is included, which is crucial for holding a load in place when power is off, ensuring safety.
