This new type of motor technology is more. And with the introduction of those types of motor technologies, you also have to incorporate some type of drive for those motors, known as an inverter. Many auto- motive functions such as fuel or water pumps, HVAC (Heating Ventilation and Air Conditioning), curve light, head-lamp levelling, and many others, are converting from brush-type DC motor or step- per motor technology to BLDC motor technology. Within the last couple of years, we’ve started to see more washing machines become Energy Starrated through the transition to a permanent magnet or BLDC motor, which are roughly 80 efficient. The level of adoption of BLDC motor technology is increasing. Companies capable to manufacture BLDC motors with integrated intelligent electronics inside, together with a low cost approach are still not easy to find. Even though there are many BLDC motor manufacturers in place, especially for the tiny BLDC motors, there are not so many integrated control electronic solutions on the market. But many of them are establishing the BLDC motor as a basis for new product developments. Most companies are still focused on motor technology like brush- type DC motors, stepper motors, etc. There are plenty of BLDC manufacturers in the US. The need for drive concepts that work with a wide range of motors, and the extreme demands made on efficiency, system design and network ing options have major impact upon the actuator electronics. It is also important to reduce exhaust emissions and lower the fuel consumption. Typically automotive components must support low system cost, small, light and reliable, and show a high degree of efficiency. Because of their technical advantages and increased efficiency, these types of motors are replacing brush-type motors in many existing applications.
These include brushless DC motors (BLDC), permanent magnet synchronous motors (PMSM) and stepper motors. The various options of semiconductor integration are opening up an ever-growing array of applications for distributed intelligent small drive solutions based on synchronous motors.
