Excellent brushless motor controller should have the advantage of
under double pressures of energy shortage and stringent environmental requirements, higher efficiency and better dynamic performance and lower operating noise, has become the inevitable trend of motor driver design. In efficiency, noise, weight, life has the advantage of brushless dc motor has become a new hot.
from the traditional AC motor design to more energy efficient brushless motor, is becoming a motor control application designers chasing hot spots at present. However, if the designer cannot effectively gain advanced, complex motor control algorithms, no matter choose which kind of method, is challenging.
excellent brushless motor controller should have what advantage? Of course is not only related to advanced or high-speed processor, more important is that, to mature advanced semiconductor technology and modular combination of brushless motor control repositories. A new type of brushless dc motor need more sophisticated electronic control. But many of the traditional motor industry engineers know only the hardware, the lack of the electronic control algorithm and converts complicated digital computing software coding experience and proprietary technology.
in order to achieve high reliability, low cost and high efficiency of the motor, the industry from the sensor to the sensorless transformation trend is clear. For example, in the traditional field oriented control motor design, adopting rotor sensor can increase both the cost ( Need sensors, power supply, special wiring and connectors, installation and maintenance) , and also may reduce reliability ( Harsh conditions there is an electrical noise, performance degradation, easily affected by the temperature and humidity) , which has adverse effects on the system. In addition, in the enclosed compressor or large traction equipment in many applications such as sensor is also completely impractical.
if the brushless motor the continued rapid development of the industry, can appear the solution: not only can provide modular brushless motor control software library, thus minimizing the software design work, can also provide additional features to implement system of programmable control and communication interface, and hardware protection and steady simulation controller, that for the brushless motor controller industry will be a milestone by leaps and bounds.
