BSBY_f010 DC fan manufacturers brand [motor] Shenzhen Xin Xin speeding speeding Motor Co., Ltd. has always adhere to the "people-oriented" management philosophy and "pragmatic innovation" concept of development, the implementation of scientific management. Products are exported to foreign markets, and to require the production of various products according to customer's special. The company's own MDOVPD (Modern speeding) brand in the community has been recognized by our customers and trust. The product has passed the UL, CE, ROHS, CCC and other safety certification, and is widely used in communications equipment, network chassis cabinets, automation machinery and equipment, medical equipment, stage equipment, LED display, welding machine and other ancillary equipment services. DC fan manufacturer specializing in the production of the first brand Xin speed DC fans, DC fans, DC blowers, AC fans and other fans fan. Xin speeding today to teach everyone know that is applied to the DC fan is called a single ball bearing mechanical equipment accessories. Single ball bearing between the rotor and stator are lubricated with the ball, and with oil. It overcomes the short oil bearing life, running instability problems, but rising costs are extremely limited. Absorb the advantages of a single ball bearing seal bearings and double ball bearings. The bearing life raised to 40,000 hours, after which the ball, run the noise has increased, but still less than the double ball bearings. Low noise and long life are the characteristics of a single ball bearing overcome noise dual ball high, high cost, difficult shortcomings inherited the advantages of double ball longer life - absorbed the advantages of low oil seal bearing noise. Single ball bearing can be said that in the low-cost choice for bearing - with its comparable hydraulic bearing life ~ 4 ~ 50,000 hours, the advantage of long-term use does not increase noise, without adding a lubricant, a single ball bearing in the long-term use a slight increase in noise can add grease to solve the problem - but not the hydraulic bearing, so the high hydraulic bearing difficulty, high price. The DC fan is through the DC voltage and electromagnetic induction, the electrical energy into mechanical rotation so as to drive the blades, collectively known as the DC fan. DC fan is to rely on the coil and the IC constantly switching from driving blades rotating magnetic induction. There are more than two rotor coil winding made from enameled wire, called windings. Generates a magnetic field when a current passes through the windings, the role of the magnetic field and the stator magnetic field generating power. Since the stator is stationary, so the rotor is rotated under the action of forces. DC fan motor speeding manufacturers preferred Shenzhen Xin Xin speeding is your best choice.
