BLDC Motor Controllers: Features & Types

Sinotech    April 9, 2013

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…

Benefits of the Three-phase Brushless DC Motor Technique

Sinotech    March 19, 2013

Gaining popularity through various industries, the brushless DC motor is a type of synchronous motor. The permanent-magnet rotors within the BLDC motor use electronic sensors that detect the rotor’s position and a DC supply that powers an AC signal inverter. Instead of using a traditional commutator with brushes, the BLDC motor has stator windings that get electronically commutated. The lack of a traditional commutator gives the brushless DC motor several benefits over other types of motor drive architectures. These benefits include: Higher efficiency Less maintenance Ability to operate at higher speeds Smaller sizes No voltage drops across brushes (because there…

Understanding Two-phase Stepper Motor Winding Arrangements: Biopolar and Unipolar

Sinotech    February 26, 2013

The stepper motor is a type of brushless DC motor. It gets its name from the number of equal steps it uses to complete a full rotation. When the motor is the right size for its application, you can command it to move and hold during one of its steps without a feedback sensor. Instead of having continuous rotation, the stepper motor uses toothed electromagnets powered by an external control circuit. Because the teeth are slightly offset, the gears rotate, or step, slightly when the electromagnets are turned off and on. With two-phase stepper motors, there are two basic winding…

Brushless DC Motors in Medical Applications

Sinotech    January 22, 2013

As the medical industry advances, so does the brushless DC motor. While connected to a DC power source, BLDC motors don’t have windings attached to the rotating shaft or armature, because this is where the magnets are. While the features brushless DC motor manufacturers integrate may seem insignificant to the lay person, the consequential benefits have helped revolutionize the medical industry. Medical Applications that Use a Brushless DC Motor Breathing devices: Positive Airway Pressure (PAP) respirators that aid in the treatment of sleep apnea have BLDC motor-powered blower fans that help regulate airway pressure. Blood clot prevention: Air pumps that…

Differences in BLDC Motor Controller Applications

Sinotech    January 7, 2013

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…
