In the world of industrial automation, where precision, reliability, and power converge, the choice of a servo motor can define the capabilities of an entire machine. Among the leaders in motion control, Mitsubishi Electric offers robust solutions for demanding applications. Today, we focus on the HA-LP11K2B, a low-inertia, medium-to-high power servo motor engineered for performance where it counts.

Core Specifications at a Glance

The HA-LP11K2B is built for substantial tasks. At its heart is a powerful 11.0 kW (kilowatt) rated output, providing the necessary force for driving large-scale industrial systems. It delivers this power at a rated speed of 2000 revolutions per minute (r/min), balancing high torque with operational efficiency.

A key feature for safety and operational control in vertical or high-inertia applications is its integrated electromagnetic brake. This built-in braking system ensures secure holding and controlled stopping. The motor is designed with a standard straight shaft and offers an IP44 protection rating, making it resistant to the ingress of solid objects larger than 1mm and water splashes from any direction, suitable for many industrial environments.

Engineered for Performance: Low Inertia and Smart Design

The "LP" in its model name signifies its place in Mitsubishi's Low Inertia series. This design philosophy is critical for applications requiring rapid acceleration and deceleration. With lower rotor inertia, the HA-LP11K2B can change speed more quickly and respond with higher bandwidth to control signals, which translates to shorter positioning times and enhanced productivity for cyclic processes.

For motors in this power range, thermal management is crucial. The HA-LP series employs a fan-less design for its 11kW and 15kW models. By eliminating the cooling fan, Mitsubishi has achieved a more compact structure and reduced overall volume and weight compared to previous series with similar power ratings. This design not only saves space in crowded machine panels but also improves reliability by removing a potential failure point (the fan motor).

Precision control is further enabled by a high-resolution encoder. While specific resolution for the HA-LP11K2B isn't detailed in the available sources, similar Mitsubishi servo motors in its class feature high-precision encoders (e.g., 131,072 pulses/revolution) that provide exceptional feedback for accurate positioning and smooth low-speed operation.

Built for Demanding Real-World Applications

The technical prowess of the HA-LP11K2B is best demonstrated by the challenging roles it is designed to perform. Its combination of high power, dynamic response, and reliability makes it a prime choice for several core industrial sectors:

• Injection Molding Machines: Providing the precise and powerful clamping force required for consistent, high-quality production cycles.

• Semiconductor Manufacturing Equipment: Enabling the exact and repeatable movements needed in cleanroom environments for wafer handling, photolithography, and assembly.

• Large-Scale Material Handling Systems: Driving conveyor systems, automated storage and retrieval systems (AS/RS), and other logistics automation that demands continuous, reliable power.

• Press and Stamping Machines: Delivering the high torque and rapid cyclic motion necessary for metal forming and punching operations.

Integration and Control

To unlock its full potential, the HA-LP11K2B is designed to work seamlessly with Mitsubishi's advanced servo amplifiers, such as the MR-J4 series. This integration ensures optimal performance, leveraging features like real-time auto-tuning, advanced vibration suppression, and support for various control networks (like CC-Link IE) for streamlined connectivity in smart factories.

The Mitsubishi HA-LP11K2B is more than just a motor; it's a strategic component for high-performance automation. It successfully bridges the gap between substantial power output and the agility required for modern, fast-cycling industrial machinery. For engineers and machine builders in fields like plastics, semiconductor, and heavy automation, selecting the HA-LP11K2B means investing in a drive solution that offers reliability, precision, and the backing of Mitsubishi's extensive motion control ecosystem.
