Dc motor dc converter smoke lampblack machine advantage analysis use permanent magnet brushless dc motor with field data, rather than the electric field, under the same conditions, small volume, light weight. And brushless motor has high efficiency and energy saving, good control performance, high reliability, long life and low noise level strengths, is being more and more alternative communication electrical appliances category. About lampblack machine system communicate with single-phase motor, brushless dc motor has the following advantages: 1. Speed: now communication machine can only do three gear speed regulation, and brushless dc motor can at 0Do infinitely adjustable-speed between 1800 turn, can greatly facilitate the user choose the appropriate speed. Increasing the use of product comfort. 2. Noise: completed the launch noise and noise of two layer down: first, dc variable frequency soft start, the working conditions of balancing eliminates the noise occurs when oil absorption. Second, the user can select different frequencies according to use demand, at 0Between 1500 turn, choose the corresponding working conditions, noise has been in a low range. 3. Air: brushless dc motor itself with high starting torque, overload capacity is strong, the characteristics of the load characteristic hard. Users to use the motor rotation speed is higher than communication, air volume is higher than communication motor. 4. Power system aspect: efficient brushless dc speed regulation system according to some strengths. On the lampblack machine full pressure power, can connect the motor 7 - higher8% to 29. 78%. 5. Energy efficiency: energy saving has become the development direction of future home appliance, take lampblack chance every day at home will be in the electronics, although every time using the time is not long, but because now use the communication of the motor power is too low, the energy consumption is still a lot. And use dc motor energy saving space is very large, after test, under the same air communication asynchronous motor needs 180 w power input, and dc motor needs only 80 w. The dc motor in power than communication by more than 50% higher than that of the motor. 6. Electrical components and temperature rise: brushless dc motor for use permanent magnet structure, motor component as long as the communication of the motor is 70%. At room temperature when running at full speed of the motor temperature rise as long as the communication by 50%. 7. System reliability: the application of brushless dc speed regulating system in smoke lampblack machine now has been very mature, the reliability of the system is also verified in many products.
