Rewinding machine <br> Motor service professional competition is extremely fierce; when the repair can not deal with the customer's reliability problem; the warranty claim and the costly return can reduce the surplus talent; and endanger the customer's loyalty. SKF has the corresponding products, talents and Technology; to promote yield, improve bearing life, customer loyalty; and reduce warranty returns.
In the electric motor industry; top quality and ability to handle problems is critical to maintaining profitability and customer loyalty. SKF has now won OEM quality awards from many quality-recognized companies. After working with SKF; you can use The resources provided by this tried and tested protagonist.
King King Motor
Motor <br> the most common type hydrodynamic bearing (also called sleeve or sliding) bearings and housings using this technique is considered to be highly cost approach; liquid bearings and power jack can cost 7-8% of the total cost of the equipment. However, there are many applications that do not require liquid dynamic bearing technology. In order to provide cost-effective and outstanding treatment solutions; SKF developed a set of two flanged housings Shaft system; each bearing housing is equipped with a roller bearing. Compared with similar sleeve bearing equipment; this type of SKF treatment has an outstanding price/performance ratio.
High capacity motors and generators
serialization specification
motor <br> such stock supply is generally small and medium; ranging from 1-500 kilowatts reliable and trouble-free operation is key to the production rate of progress so;.. SKF's quality bearings It is the best choice; in the long run; it can help you to maintain the surplus of equipment; reduce the cost.
SKF not only supplies bearings that are more reliable and durable, but also provides a variety of outstanding treatment solutions that improve the motor's function; for example, insulated bearings that eliminate overcurrent.
1. <br> in the
variable speed drive motor; stray currents can lead to bearing raceways and rolling body surface pits constituting the variable drive with a pulse width modulated drive (VSD) motor exhibits this particular schematic representation of a bearing current. The damage caused will lead to noise and temperature rise, lubricant efficiency decline, excessive oscillation; and can lead to bearing failure. If this problem is not properly handled; the service life of the bearing will be greatly shortened; then affect the overall benefits.
Insulated bearings not only save the time and cost required for portrayal and equipment production; they also reduce the need for repair and protection; and then improve overall cost performance.
In addition to quick and easy-to-use processing solutions, you can also use SKF's expertise to support your analysis and build operations; and provide you with ideas; so that the equipment can carry the best overall function and benefits.
2. Encoder <br> Stray current is formed by the inherent influence of the inverter; it is a common problem. Because the bearing of the motor or generator is protected; so this problem is generally transferred to the subordinate equipment; the encoder bearing is particularly simple Present this kind of problem.
Motors <br>
use for a particular use
case for a particular occasion is mainly low-capacity product; ranging from 1 to 500 kilowatts of these motors for fans, pumps and compressors for the intended application occasions;. Used in these Occasion; the reliability of the motor is extremely important. The same; generators; especially wind turbines; it is necessary to deal with the same or even more stringent requirements.
Regarding the motor for a specific application; picking the right bearing and bearing equipment to optimize the function; it is very important to be accustomed to the operating conditions of the specific application. SKF's professional knowledge in this area can bring further benefits; Reliability and functionality; then improve the equipment's surplus ability.
1. Wind Turbines
In the competitive and rapid development of wind energy occupation; cost effectiveness, product reliability and excellent supply service are important requirements. In variable speed generators; overcurrent causes a high risk of bearing damage. Know how to describe the treatment plan for bearing protection. The success of the new project can have a decisive role. In the field of insulated bearings; SKF is in a leading position.
Thanks to its knowledge in the field of wind energy; SKF can provide superior technical support and proposition. SKF treatment solutions provide outstanding functionality and unparalleled service life.
2. Forklift Motors <br> These years; variable speed drive systems have replaced the simple DC motors in forklifts. However, cost-effective and powerful communication motors generally require a set of rated feedback systems; used to supply motor speed and related Information such as the direction of rotation of the system controller. If properly mapped; such systems are highly reliable, easy to install, space-saving and cost-effective.
3. Encoder <br> Stray current is formed by the inherent influence of the inverter; it is a common problem. Because the bearing of the motor or generator is protected; so this problem is generally transferred to the subordinate equipment; the encoder bearing is particularly simple Present this kind of problem.
