Product Features


Superior Energy Efficiency

By adopting high-performance rare earth permanent magnet materials, paired with a specialized stator slot design and optimized rotor structure, the AC Permanent Magnet Servo Motors achieve an efficiency level that meets the IE4 standard—the highest energy efficiency rating for industrial motors. This design reduces energy consumption by 15%-25% compared to traditional asynchronous motors, cutting long-term operational costs for users.


Compact & Lightweight Design

Compared to asynchronous motors with the same power output, these servo motors are 1 to 2 frame sizes smaller and significantly lighter. The compact structure saves valuable installation space in equipment (such as CNC machines and hydraulic presses), allowing for more flexible layout designs in industrial workshops without compromising performance.


High Dynamic Performance

With a smaller rotational inertia and larger starting torque, the AC Permanent Magnet Servo Motors deliver rapid response times—critical for applications requiring frequent start-ups and speed adjustments. Their wider operating frequency range (adaptable to 1000rpm - 2000rpm) ensures stable performance even in scenarios with variable speed demands, such as injection molding machines.


Enhanced Reliability & Long Lifespan

The motor’s optimized winding design reduces operating current, which in turn lowers temperature rise during long-term use. This not only prevents overheating-related failures but also extends the motor’s service life by 30% compared to conventional asynchronous motors. Additionally, the IP54 protection level shields internal components from dust and moisture, further enhancing durability in harsh working conditions.


Universal Compatibility

Designed with the same mounting and connection structure as standard asynchronous motors, the AC Permanent Magnet Servo Motors can directly replace old asynchronous motors without modifying equipment frames or electrical systems. This plug-and-play compatibility minimizes replacement costs and downtime for factories upgrading their machinery.


Simplified Control System

Adopting a frequency conversion vector control mode, the motors offer high control accuracy (up to ±0.1% speed deviation) while reducing fault points in the control circuit. This simplifies operation for maintenance teams and ensures consistent performance, even in precision-dependent applications like CNC machining.


Modular Customization

Users can flexibly configure additional modules based on specific needs, including independent drive fans (for heat dissipation in high-temperature environments), encoders (for real-time speed monitoring), and brakes (for emergency stopping in safety-critical scenarios). This modular design makes the motors adaptable to diverse industrial requirements.


Strong Environmental Adaptability

Unlike traditional motors that struggle with long-term low-speed operation or frequent start-ups, the AC Permanent Magnet Servo Motors maintain stable performance in extreme working conditions. Whether in high-dust die-casting workshops or high-humidity hydraulic press rooms, the motors operate reliably without performance degradation.


Applications


Key Application Fields

The AC Permanent Magnet Servo Motors are engineered to meet the demands of multiple industrial sectors, with core applications including:


Injection Molding Machines

Injection molding requires frequent start-ups, stable low-speed operation (for material melting), and precise speed control (for uniform product molding). The motor’s large starting torque and low rotational inertia ensure smooth material injection, while its IE4 efficiency reduces energy costs for 24/7 production lines.


Die-Casting Equipment

Die-casting involves high-temperature environments and heavy-load operations. The motor’s IP54 protection level resists dust and heat, and its compact size fits into the limited space of die-casting machines. Additionally, its ability to handle frequent speed adjustments ensures consistent die-casting quality for metal components.


Hydraulic Presses

Hydraulic presses rely on high torque to drive pressure plates, and the AC Permanent Magnet Servo Motors deliver the required 12kW - 280kW power with minimal energy loss. Their stable performance during long-term low-speed operation prevents pressure fluctuations, improving the accuracy of pressed products (such as automotive parts).


CNC Machining Centers

CNC machines demand ultra-high control accuracy for precision cutting and engraving. The motor’s frequency conversion vector control mode ensures speed deviations of less than ±0.1%, while its rapid response time allows for quick tool changes and speed adjustments—critical for complex machining tasks (e.g., aerospace component manufacturing).


FAQ


1. What voltage does the AC Permanent Magnet Servo Motor use?

The motor operates on a standard 380V industrial voltage, which is compatible with most global industrial power systems. No additional voltage converters are required for use in factories that follow international electrical standards.


2. Can the AC Permanent Magnet Servo Motor replace asynchronous motors directly?

Yes. The motor shares the same mechanical structure (mounting holes, shaft size, and connection interfaces) as standard asynchronous motors. This means it can replace old asynchronous motors without modifying equipment frames or electrical circuits, reducing upgrade time and costs.


3. What protection level does the motor have, and is it suitable for harsh environments?

The motor has an IP54 protection level, which means it is dust-tight and protected against water splashes from any direction. This makes it ideal for harsh working conditions, such as high-dust die-casting workshops, humid hydraulic press rooms, or factories with frequent water cleaning.


4. What control mode does the AC Permanent Magnet Servo Motor use, and how accurate is it?

The motor uses a frequency conversion vector control mode, which provides high control accuracy—with speed deviations as low as ±0.1%. This level of precision is suitable for precision-dependent applications, such as CNC machining and injection molding, where even small speed fluctuations can affect product quality.
