in the auto industry development bring new development opportunity for brushless dc motor controller drive systems, automotive systems widely used motor controller for the motor controller manufacturers has brought benefits. According to a recent survey, 2012 to 2017, applied in the automobile industry of the permanent magnet brushless dc motor controller shipments to be more than the dc servo motor controller and step motor controller. Permanent magnet brushless dc motor controller shipments will rise 52%, the sales will be more than 4. 6. 2 billion units. Permanent magnet brushless dc motor controller is widely used in automotive transmission system and chassis applications. The main mechanical drive applications ( Such as power steering, transmission driver and engine cooling system) More and more tend to use motor controller driver, it also makes the use of brushless dc motor controller greatly increased number. Among them, the service life of the motor controller and power are limited space transmission system and must consider the quality of the engine cooling system. Although the dc servo motor controller is widely used in automobile industry, however, its market development potential is not as good as permanent magnet brushless dc motor controller. Brushless dc motor controller application field relative to update, since this year has been rapid development. Plug-in electric car sales growth is expected to brushless dc motor controller shipments to provide more room for growth. Dc servo motor controller sales are expected to surge in 2017 years ago, shipments of 30% above the 2012 level. Dc servo motor controller, the development of permanent magnet brushless dc motor controller depends on carrier - motor controller - The number of cars increase. Permanent magnet brushless dc motor controller suppliers because the whole auto industry controller higher utilization benefit. However, low-end applications such as ( Door lock, electric Windows) Such as sales of dc servo motor controller is far lower than the drive system and chassis applications. In 2012, nearly 60% of the motor controller is applied to the transmission system and chassis applications, 32% motor controller has been applied to automobile industry. Among them, the power rating higher than average 30 watts of motor controller of the sales price is less than 30 watts price is three times higher. Because of the price difference, powertrain and chassis application of motor controller suppliers can get more benefits than low-end application motor controller suppliers. Although the use of dc servo motor controller as in application and popularization of mechanical and electrical industry, but there are expected to think, permanent magnet brushless dc motor controller of sales from 2012 to 2017 will exceed twice of the sales of the dc servo motor controller. , dc servo motor controller and the permanent magnet brushless dc motor controller their average annual sales growth of 3 respectively. 5% and 7%. The study covers used in automotive industry of the dc servo motor controller, permanent magnet brushless dc motor controller and step motor controller ( Except the traction motor controller) , application areas include: transmission/chassis system, airflow, braking, adaptive head lamp, electric rearview mirror, dial, electric lock, wiper system and some of the other electric vehicles.
