In the field of electric vehicles, although both permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC) are based on permanent magnet technology, there are essential differences in design concepts and control methods. The following analyzes the applicability of the two from the perspective of technical characteristics and vehicle…
Late at night, when you turn on the table fan to enjoy the cool breeze, you can hardly hear the sound of the motor running; or when you use an electric toothbrush, you can only feel slight vibrations without annoying noise – behind this, it is the BLDC motor (brushless…
In the fields of smart home, industrial automation, etc., from the wind speed regulation of smart fans to the speed control of precision machine tools, the precise speed regulation of BLDC motors (brushless DC motors) is indispensable. However, many engineers and equipment users are often confused: Why is the motor…
When you are disturbed by the harsh sound of an old vacuum cleaner, or find that the power of a power tool is consuming too fast, have you ever thought about the difference in motor technology behind it? In the era of pursuing high efficiency and energy saving, brushless DC…
In the efficient operation of brushless DC motor (BLDC), accurately capturing rotor position is the core of achieving stable drive. Imagine that if the motor cannot sense the rotor state, it is like a car losing navigation, which will cause low efficiency at best and malfunction at worst. Whether it…
When you marvel at the flexible steering of drones and the silent operation of home appliances, the “power heart” behind them – BLDC (brushless DC motor) is using electronic commutation technology to achieve efficient and stable operation. However, how does electronic commutation replace traditional mechanical commutation? How does this process…
When smart home devices are running, are you curious about how the fan can smoothly switch from breeze to strong wind? On industrial automation production lines, how do motors accurately control speed to complete precision processing? Behind these scenes, pulse width modulation (PWM) technology is the key to achieving speed…
Late at night, the roar of the motors in the factory workshops is mixed with warning signals of abnormal heating of the equipment; the fan motors in the corners of the home emit pungent odors due to high-temperature operation… Motor heating not only affects the normal operation of the equipment,…
In factories, motors run continuously but consume huge amounts of energy; in home appliances, motors start and stop frequently but lack power. Many people are looking for ways to improve motor efficiency, and field-oriented control (FOC) technology is the key to solving these problems. This article will deeply analyze the…
Are you curious about why a BLDC motor without carbon brushes can rotate continuously and stably? In the fields of smart home and new energy vehicles, BLDC motors are favored for their high efficiency and energy saving, and brushless commutation is the “heart” of BLDC motors. This article will unveil…
