If torque ripple or audible noise is a concern, then the shape of the back-EMF waveform of the BLDC motor becomes very important. Most BLDC motors in fact have a sinusoidal back-EMF waveform. If you ...

To enable smooth BLDC motor control, the MCUs employ a 16-bit timer/counter with four compare channels for pulse width modulation and waveform extension. A 24-bit timer/counter provides frequency ...

As the cost of BLDC controllers continues to fall, you will see more of the new breed of BLDC motors in applications that may have used conventional PM dc motors or brush-type servomotors in the past.

Engineers who have a firm handle on losses in BLDC motors can better design efficient motors for their specific applications. Brushless DC (BLDC) motors transform electrical power into mechanical ...

Besides accepting digital data from DAQ cards or analog data from function generators to create complex waveforms, the Chroma's 63600 also provides an enhanced feature, User Defined Waveform (UDW ...

BLDC fans has an edge over regular ceiling fans owing to their advanced technology, energy efficiency, quieter operation, and additional features like variable speed control and smart ...
