synchronous motor is an AC motor whose shaft rotation is in sync with the supply current’s frequency as the motor runs at a steady state. Consequently, the integral number of AC cycles is the same as the rotation period. Continue readingA
When you need a motor for an application, you may not know if a brushless DC motor or stepper motor is best. In principle, both types are permanent-magnet synchronous motors. The difference is in their specific characteristics and mode of operation. Continue reading
Thanks to brushless DC motors, tackling home improvements projects is simpler than ever. On average, over half of the adults in the U.S. tackle a DIY project each year. Because of BLDC motors, power tools have longer run times on a single battery charge, are more compact, lighter in weight, more powerful, smarter and last longer. This infographic explores trends in home improvement projects across America, the power tools used and the evolution of brushless DC motors.
Refrigeration applications largely depend on the capabilities of the compressor, which compresses the refrigerant, and the cooling fan that blows air through and evaporator. As energy policies and market needs change, designers look to BLDC motors for efficient, low-maintenance and quieter solutions. Continue reading
A stepper motor is a type of brushless DC motor that has an equal number of steps dividing a full rotation. Micro stepper motors take a standard step, say 7 degrees, and divide it up to provide smaller steps of, for example, 3.5 degrees. As the micro-steps get smaller, the motor’s operations get smoother, which reduces the resonance within the motor and parts connected to it.
Sinotech is happy to announce that embedded logic inside brushless DC motors is a reality. By embedding custom logic circuits inside the motor, the complexity of the system decreases along with its related costs. Continue reading
