In some machining workshops, factors such as concentrated equipment, poor ventilation and high summer temperatures result in high ambient temperatures. Furthermore, metal cutting generates a significant amount of heat. Standard motors have poor heat resistance and, in high-temperature environments, are prone to coil ageing, reduced power output, frequent faults and a drastic reduction in service life. They are unable to cope with harsh, high-temperature operating conditions, which severely affects production continuity.

Conventional industrial motor cores are characterised by crude manufacturing processes and components with poor wear resistance. Prolonged high-speed cutting operations can easily lead to issues such as bearing failure, coil ageing and power degradation. With an average service life of only around 8,000 hours, these motors require frequent repairs, component replacements or even complete unit replacement. Frequent equipment maintenance not only incurs high repair and component costs but also causes production delays due to equipment breakdowns, resulting in hidden losses in production capacity.

In traditional machining setups, drilling and milling operations require two separate machines—a dedicated drilling machine and a milling machine—resulting in high procurement costs and a large footprint. Many small and medium-sized machining workshops have limited floor space; cramming in multiple machines not only occupies a significant amount of production space but also necessitates two sets of operators and two sets of maintenance consumables. This leads to high equipment idling rates and severe waste of resources, placing immense pressure on micro and small enterprises in terms of capital investment.

1. Many machining workshops frequently encounter issues with standard motors lacking sufficient power when machining hard materials such as steel, stainless steel, titanium alloys and cemented carbides:

The machining industry is currently undergoing a gradual transition towards automation and intelligent manufacturing. However, the motors fitted to many older machines do not support integration with CNC systems or automated interlinking, making them incompatible with automatic tool changing and batch programmed machining. As a result, enterprises are forced to rely on manual operation, which is labour-intensive and results in low production efficiency. This makes it difficult to achieve standardised and intelligent production, and prevents them from keeping pace with the industry’s pace of modernisation.

Industrial processing equipment operates continuously over long periods, with motors being the primary consumers of electricity. Traditional standard motors are characterised by high energy consumption, significant power loss and substantial wasteful power usage; long-term mass production results in high electricity bills, thereby increasing a company’s production and operational costs.

Cutting tools are the core consumables in drilling and milling operations. Traditional motors suffer from unstable cutting power, excessive vibration and uneven feed rates; as a result, cutting tools are subjected to uneven forces during machining, making them highly susceptible to problems such as premature wear, chipping, breakage and deformation. This leads to frequent tool replacement, keeping monthly consumables procurement costs high; moreover, tool damage can directly result in workpieces being scrapped, thereby doubling production costs.

1. Mass industrial production requires equipment to operate continuously for extended periods. Standard spindle cooling systems are rudimentary; under high-load conditions, heat accumulates rapidly, leading to thermal deformation, speed drift and loss of precision. 2. Common faults include: whilst the first workpiece may meet specifications, subsequent production runs result in increased dimensional deviations, misaligned holes and inconsistent engraving depths. This may also trigger overheating shutdown protection, interrupting assembly line production.

1. Standard spindle bearings suffer from low precision and poor dynamic balance. During high-speed operation, they produce severe vibrations and piercing noise. This not only causes workshop noise levels to exceed standards and creates a poor working environment—posing a risk to operators’ health—but also triggers resonance throughout the machine, leading to tool vibration, rough machining surfaces and chipping of workpieces.
