**Rewinding Machines**
The competition in the motor repair industry is very intense. When repairs fail to address customer reliability issues, warranty claims and costly returns can reduce profits and damage customer loyalty. SKF offers a range of products, expertise, and technology that help improve efficiency, extend bearing life, and reduce warranty returns.
In the electric motor industry, top-quality performance and problem-solving capabilities are essential for maintaining profitability and customer satisfaction. SKF has earned OEM quality awards from many reputable companies. By working with SKF, you gain access to proven resources and support that can enhance your operations.
**King Motor Motor**
Hydrodynamic bearings (also known as sleeve or sliding bearings) are commonly used in this application and are considered a cost-effective solution. Liquid bearings and power jacks can account for up to 7–8% of the total equipment cost. However, not all applications require liquid dynamic bearing technology.
To offer more cost-effective and high-performance solutions, SKF developed a two-flanged housing shaft system, each equipped with a roller bearing. Compared to traditional sleeve bearing systems, this SKF solution provides an excellent price-to-performance ratio.
**High-Capacity Motors and Generators**
Standardized motors typically range from 1 to 500 kW. Reliable and trouble-free operation is crucial for production efficiency. SKF’s high-quality bearings are the best choice for long-term performance, helping maintain equipment availability and reduce costs.
SKF not only supplies more reliable and durable bearings but also offers advanced treatment solutions that enhance motor performance. For example, insulated bearings eliminate harmful currents, improving overall system reliability.
**1. Variable Speed Drive Motors**
In variable speed drive (VSD) motors, stray currents can cause pitting on bearing raceways and rolling elements. This issue is common in pulse-width modulated (PWM) drives and can lead to noise, temperature rise, reduced lubricant efficiency, and excessive vibration. If left unaddressed, it can significantly shorten bearing life and affect overall system performance.
Insulated bearings help prevent these issues, saving time and reducing maintenance costs. They also improve cost efficiency by minimizing repair needs.
In addition to easy-to-use solutions, SKF’s technical expertise supports your analysis, design, and optimization efforts, ensuring your equipment operates at peak performance and delivers maximum value.
**2. Encoder Bearings**
Stray currents caused by inverters are a common issue. While the motor or generator bearings are usually protected, this problem often shifts to subordinate components like encoder bearings, which are particularly vulnerable.
**Motors for Specific Applications**
These motors are typically low-capacity, ranging from 1 to 500 kW, and are used in fans, pumps, and compressors. Reliability is critical in such applications. Similarly, generators—especially wind turbines—require even stricter performance standards.
Choosing the right bearing and bearing system for specific applications is key to optimizing performance. SKF’s deep expertise in this area helps ensure reliability, functionality, and long-term equipment efficiency.
**1. Wind Turbines**
In the fast-paced wind energy sector, cost-effectiveness, product reliability, and excellent service are essential. In variable-speed generators, overcurrents pose a significant risk to bearing integrity. Proper bearing protection is vital for project success.
SKF leads in insulated bearing technology, offering superior support and long-lasting performance tailored to wind turbine applications.
**2. Forklift Motors**
In recent years, variable-speed drive systems have replaced simple DC motors in forklifts. These systems often require feedback mechanisms to monitor motor speed and direction. When properly implemented, they are reliable, easy to install, and cost-effective.
**3. Encoder Bearings**
As previously mentioned, stray currents caused by inverters can affect encoder bearings, making them a common point of failure. Proper bearing selection and insulation are essential to prevent damage and ensure smooth operation.
