When new energy vehicles travel on urban roads, range anxiety and slow power response are always problems in the minds of users. Whether it is a sudden drop in range in cold winter or insufficient power when overtaking at high speed, it is testing the performance of the whole vehicle.…

When you use a silent fan or control a drone, sensorless BLDC motor technology may be at work behind the scenes. This technology that can accurately control speed without physical sensors is very popular, but how to overcome the difficulties of starting and running? This article will analyze the technical…

In the fields of smart wearable devices, precision medical devices, etc., the demand for miniaturization of BLDC motors is becoming increasingly urgent. However, how to ensure or even improve performance while reducing the size has become a difficult problem for engineers. This article will reveal how innovations in materials and…

Looking at the rising electricity bills in the factory, the equipment maintenance staff are anxious: Why can’t the energy consumption be reduced even though BLDC drivers are used? Not only is the cost pressure huge, but it is also difficult to meet the increasingly stringent energy-saving and emission reduction requirements.…

In the factory workshop late at night, a precision equipment was forced to stop working due to a sudden failure of the BLDC driver. The maintenance personnel repeatedly checked under the flashing alarm light but had no clue; in the laboratory, the motor debugged by the scientific researcher caused the…

In the fields of industrial automation, new energy vehicles, smart homes, etc., BLDC drivers have become core components with their advantages of high efficiency, energy saving, and precise control. However, many engineers and equipment operation and maintenance personnel have encountered such a problem in actual use: after the equipment has…

In the wave of popularization of electric vehicles, the cruising range has always been a “pain point” in the minds of consumers. When car owners frequently look for charging piles due to power anxiety during long-distance travel, or find that the cruising range has been greatly reduced in the cold…

In the workshop late at night, the equipment suddenly stopped. When the maintenance master took it apart, he found that the BLDC drive was “on strike” again. Frequent downtime, high energy bills, and difficulty in meeting the accuracy requirements… These problems that trouble countless engineers and business owners are often…

In the wave of intelligent manufacturing and precision control, the servo motor serves as the power core, and its encoder is like a “neural sensor”, continuously transmitting position and speed feedback in real-time to ensure the stable operation of the system. However, encoder faults under complex working conditions are like…

The core of a BLDC drive system lies in electronic commutation. Different from traditional brushed motors that use mechanical commutators and brushes to switch the current direction of the stator windings, BLDC drives rely on electronic circuits and control algorithms to achieve this process. Specifically, the drive system obtains the…
