The brushless DC motor is made up of a permanent magnet like rotor and a polyphase windings stator. Brushless DC (BLDC) electric motors are synchronous motors that do not contain brushes, which are switched electrically via an electric drive to supply the stator winding. The controller supplies the current pulses to the motor windings that control the speed and torque of the motor.
What are different benefits of brushless DC motor that is promoting the growth of the market?
The global brushless DC motors market size is US$ 9 billion in 2018, and it is expected to reach US$ 19 billion by the end of 2025.
The global market for brushless DC motors is increasing due to the rising demand for brushless DC motors in pulp and paper, chemical, marine, semiconductor, food, aerospace, electronics industries etc.
The growth of brushless DC motors as a traction motor in electric vehicles is increasing due to decreased demand from heating, ventilation, and air conditioning (HVAC) application. Additionally, the high cost for brushed DC motor and the move towards energy-efficient machinery have a positive effect on market growth.
The hydraulic system is replaced with the electric system by the brushless DC motor in the automotive industry, especially for the application in steering boxes.
For instance, the brushless DC motors market has seen a tectonic wave as its advantages over other motors have been various.
In comparison to brushed DC motors, brushless DC motors require lower maintenance, triggering demand globally. Brushless DC motors operate effectively at all speeds, offer a greater range of speed, reduced dimensions with better thermal features and less electric noise generation compared to other motors. They provide high efficiency, as these motors can be operated with maximum rotary power. The brushless DC motors are capable of delivering an enormous amount of torque at a fast rate. These advantages of brushless DC motors will lead to market growth.
The adoption of the brushless DC type sensor-less controls would improve product efficiency and longevity, reducing the number of electric contacts and mechanical misalignments. Major players around the world have begun developing advanced motors offering high energy efficiency. This is further projected in the near future to generate growth opportunities for the industry. Furthermore, the rising developments in industrial robotics would give additional growth opportunities to the brushless DC electric motor market.
However, the use of sensors in the BLDC motor increases the price of brushless DC motors. This is a major limiting factor for the expansion of the worldwide market. Furthermore, the low-quality availability of expensive brushless DC motors in the grey market can negatively impact the growth of the global brushless DC motor market.
