Industrial electronic manufacturers and developers, micronas said if brushless dc confidential will be the foundation for the development of the motor in the future, then eliminate the brushless dc motor control too expensive is too complicated this one have been accepted by the market point of view.
in the first place, the geometry of brushless dc motor structure is smaller, lighter weight, conforms to the market demand for light weight design and enhanced performance. Second, with the use of permanent magnets, the rotor without core loss, so the brushless dc motor is more efficient, at the same time, the use of permanent magnets can also reduce the maintenance, prolong the service life of the machine. Third, through the use of appropriate transformation algorithm, thermal performance is improved, which can realize higher speed range of the motor and the dynamic response time, better electromagnetic isolation, and torque response is better.
although now there are a lot of brushless dc motor manufacturers, but few on the market with integrated electronic control scheme. To find a can be equipped with a highly integrated electronic control the low cost of brushless dc motor manufacturers are still very difficult.
brushless dc motor technology market is expected to grow. First of all, the cost of electronic products falling would make it cheaper. Today's market requires motor lighter weight, smaller volume, higher power density, the dongguan model aircraft brushless motor, these factors promote the development of brushless dc motor. Brushless dc motor speed using the trend is likely to increase the diversity of the motor and functional, and are easier to implement intelligent drive connected to the Internet.
through the use of single chip solutions can reduce the design time, adopt the way of software can be applied to different motor type and properties. Now, brush dc motor solution can be made of appearance looks like but internal can realize intelligent motion control of the brushless dc motor.
it must be admitted that the conversion of the brushless dc motor, especially in the aspect of programming is very complex, but the right controller unit is different. Integrated electronic control can achieve better self diagnosis function and automatic adjusting system parameters. Finally, the single chip design solution can reduce the complexity of the circuit.
adjusted motor parameter to change the switching scheme in software can be suitable for different motor types and properties. Hardware and software of the high level of repeated use and can realize quick response to customer demand change. Compared with the standard of micro controller or state machines are usually only applies to a specific motor type or application.
