Brushless DC motor (BLDC) systems are the most preferred systems for the simple reason that they are cost-effective. The cost, which includes maintenance, downtime and costs related to energy requirements, is lower for these systems as compared to their brush type counterparts. The performance of any motor depends on the performance of its two components namely, motor and controller. This is particularly true for BLDC motors, in which BLDC motor controllers play a crucial part in determining its performance. Sinotech’s Brushless DC Motor Controller Design Sinotech’s aim is to provide clients with solutions that are tailor made for their requirements…
BLDC Motor Controllers: Features & Types
When you look through a DC motor catalog, you’ll notice that no two BLDC motor controllers are alike. Because they’re often used for applications that require variable or adjustable speeds, BLDC controllers must be flexible enough to suit the application. Some controllers simply provide the electronic commutation to make the motor operate as well as the ability to reverse direction. More complex controllers may integrate a programmable microcontroller so that the user can program lots of motor functions. Some BLDC controllers are small enough to put inside the motor case. These “embedded” controllers make it easy to substitute a high…
Differences in BLDC Motor Controller Applications
You see examples of BLDC motor controllers almost everywhere, but you may not know it. BLDC motor controllers use IGBTs (integrated-gate bipolar transistors) or FETs (field-effect transistors) to provide power to the motor’s coils. Many also use electronic commutation to drive coils, which switch the current between different phases. When compared to their brush-type counterparts, BLDC motors are often considered superior. Here’s a look at the different components within their controllers: Switch. This component breaks an electrical circuit, thus diverting or interrupting the current. The most common type of switch is an electromechanical device that you manually operate. Other kinds…
