Centrifuge application field widely, suitable for chemical, oil, food, pharmaceutical, mineral processing, coal, water treatment and shipping departments. With the rapid development of centrifuges, centrifuge technology in China, the market demand is gradually increased, the centrifuge product categories are also increasingly rich, it makes a lot of users on the choice is also a lot more likely. In the centrifuge, the motor is an indispensable core parts. The same type of centrifuge can match with brush motor, brushless motor, dc brushless motor factory in dongguan, the user can choose for both the advantages and disadvantages of, also can become a standard of measure when choosing products.
brush motor, it has a simple structure, low cost, convenient connection. But there are some drawbacks, for example, in general, the machine starts working speed constant, speed is not very easy. Due to commutation device and the rotor fixed together, and the carbon brush with shell and fixed, brush motor rotates with phase switcher constant friction produces a lot of resistance to heat, therefore, has a brush motor efficiency is relatively low, and the loss is very big. Once the carbon brush wear too much, just need to replace carbon brush, short service life, maintenance complex, basically need to replace the motor directly.
brushless motor, that is, the internal structure of electrodes in the motor without carbon brush. Specifically, its light resistance mainly comes from the rotation of the rotor and stator contact point. Therefore, generally on both ends of the rotor of the brushless motor used ball bearings to reduce friction, thus, will not have a lot of friction and heat resistance. Like a brush motor, brushless motor and disadvantages. The speed control system than the cost of a brush with high-speed motor speed control system, and the centrifuge controller in use are prone to failure.
the user can according to the advantages and disadvantages of brush motors and brushless motor to choose suitable products. But in general, a brush motor manufacturing cost is low, so the market prices are more affordable, shenzhen moped motor, start the work after speed constant. Suitable for constant speed operation equipment.
and brushless motor control is strong, small power consumption, small noise, no dust and environmental protection, etc. Although there are brush motor, relative to its price is higher. Large laboratory and scientific research units, especially the application of environmental protection and energy saving would have a big advantage. The characteristics of long service life, energy efficiency, making it more and more widely used in centrifuge.
