HG-SR152K MITSUBISHI Industrial Servo Drives 24VDC (-15%~20%) –20°C To +60°C
HG-SR152K Description
The Mitsubishi Electric HG-SR152K is a super-large capacity, high-inertia AC servo motor from the MELSERVO-J4 series. It is engineered to deliver massive torque for the most demanding industrial applications that require moving heavy loads. Unlike low-inertia motors designed for rapid acceleration, the high-inertia rotor of the HG-SR152K provides exceptional load stability and smooth rotation, even under significant load fluctuations. When paired with the compatible MR-J4-350B-RJ or larger servo amplifier, this motor forms a robust system capable of precise speed and position control for large-scale machinery. It is an ideal solution for heavy-duty industries such as metalworking, injection molding, and material handling.
HG-SR152K Features
- •
Super-Large Capacity & High Torque: Designed to provide extremely high rated and maximum torque, enabling the direct drive of heavy loads without the need for a speed reducer in some applications.
- •
High-Inertia Rotor: The motor's inertia matches heavy loads, resulting in superior damping characteristics, reduced vibration, and stable operation that is resistant to load fluctuations.
- •
High-Resolution 24-bit Absolute Encoder: Provides ultra-precise position feedback and eliminates the need for a homing operation upon every power-up (battery-less absolute system), enhancing productivity and positioning accuracy.
- •
Compatible with MR-J4-B Series Amplifiers: Achieves optimal performance when integrated with the high-capacity MR-J4-B-RJ series servo amplifiers, which offer advanced vibration suppression and gain adjustment features.
- •
Robust Construction: Built with a heavy-duty frame and components to withstand the harsh conditions of heavy industrial environments, ensuring long-term reliability and durability.
- •
Smooth Rotation at Low Speeds: Advanced control algorithms minimize torque ripple, allowing for exceptionally smooth rotation even at very low speeds, which is critical for precise heavy-load positioning.
HG-SR152K Material & Applications
- •
Material: The motor housing is constructed from a robust cast iron or heavy-gauge steel frame for maximum strength and heat dissipation. The shaft is made of high-tensile strength steel, and internal components are designed to handle high continuous torque.
