Motor drivers can be used in many different applications. Design engineers face some common challenges when using motor drives in their designs. First, most of today's designs require motor drive applications and associated motor drive ics and components to provide low energy consumption and high energy efficiency. For example, if the fan driver circuit board is located inside the sealed housing, heat is generated, requiring additional energy consumption to cool it. Therefore, it is necessary to use a built-in fan to circulate cold air inside to reduce heat and manage heat dissipation. As a result, engineers may require low power losses, as well as powerful, energy-efficient cooling motors.
    Secondly, from the point of view of the end user, there is a great need to reduce the noise generated by the motor to avoid causing discomfort. The designer must also be able to compensate for any external noise or vibration in the system. Third, whether due to limited living space or user preferences, high consumer demand for compact solutions is a common consumer trend. This trend has led to a preference for smaller and less noisy motors, but this is not always possible when trying to compensate for other design requirements.
    It is important to note that the durability and safety of motors and motor drivers are critical due to the high voltage power supply required to drive white appliances and industrial applications. Not to mention the need for engineers to choose reliable motors that can precisely control speed.
