The operation of a Brush Less DC motor (BLDC motor) is based on the interaction between the stator’s stationary magnetic field and the rotor’s rotating magnetic field. The stator contains coils of wire, which are energized in a specific sequence to create a rotating magnetic field. The rotor has permanent magnets that interact with the stator’s magnetic field, causing the rotor to rotate. With their higher efficiency and power density, brushless DC motors have become an integral part of numerous machinery and equipment.
Globally rising industrialization is expected to highlight the importance of energy-efficient motors along with the automation of machinery. Such factors will subsequently fuel the growth of the global brushless DC motor market. Brushless DC motors are more efficient compared to traditional motors, which results in reduced energy consumption and lower operating costs. Thus, the growing demand for energy-efficient motors in various industries is driving the growth of the BLDC motor market.
Numerous governments across the globe have started focusing on bringing energy efficiency in the industrial sector to limit carbon emissions by considering environmental concerns.
For instance, the UK government has set several policies and regulations aimed at promoting energy-efficient machinery in various sectors of the economy. Energy Savings Opportunity Scheme (ESOS), Minimum Energy Efficiency Standards (MEES) Energy Technology List (ETL), Industrial Energy Transformation Fund (IETF) and Carbon Reduction Commitment (CRC) are a few regulations and policies that encourage energy efficiency in various infrastructures, such efforts by governments are intended to boost the demand for brushless DC motors.
The development of advanced motor control technologies, such as sensorless control and field-oriented control, has improved the performance of brushless DC motors, making them more efficient and reliable. These advancements are driving the growth of the brushless DC motor market. Moreover, rising automation in industries such as food processing, automotive and logistics is predicted to fuel the demand for brushless DC motors. Furthermore, the rotation and thermal control capabilities of brushless DC motors have created a significant opportunity for such motors to be utilized in the aerospace industry.
The electric vehicles utilize brushless DC motors to offer smoother rides with controlled heat insulation. The rising development and demand for electric vehicles around the globe are supplementing the growth of the global brushless DC motor market.
For instance, in February 2023, Okaya EV launched ‘Okaya Faast F2F’, a new electric scooter offering two-year/20,000 kilometers warranty motors. The new Okaya Faast F2F electric scooter carries 800 watts brushless DC motor that claims to provide 50-55 kmph top speed.
At the same time, in February 2023, Hop Electric announced the launch of the Hop Oxo electric motorbike that uses a brushless DC motor that is claimed to produce a peak power of 5.2 kW and a maximum torque of 185 Nm/ 200 Nm.
Moreover, the unmatched benefits offered by brushless DC motors over brushed DC motors, such as minimal electric noise, improved dependability, clean operations, reduced errors, and prolonged lifespan, are expected to boost the growth of the global brushless DC motor market globally.
Major growth actuators
Brushless DC motors are commonly used in electric vehicles due to their high efficiency, reliability, and low maintenance requirements. The increasing adoption of electric vehicles, particularly in the automotive industry, drives the demand for BLDC motors. Moreover, brushless DC motors can provide high power output in a small and lightweight package, making them an ideal choice for electric vehicles where space and weight are critical factors. BLDC motors operate smoothly and quietly, providing a comfortable driving experience for passengers.
The International Energy Agency (IEA) predicts that the global EV stock will continue to grow rapidly, with an estimated 145 million EVs on the road by 2030, and the unmatched benefits of brushless DC motors in electric vehicles highlight the future of the market with rising demand for electric vehicles across the globe.
For instance, in March 2023, Tata-backed Stryder launched a new addition to its e-bike range, equipped with a brushless DC motor that claims to offer smooth and silent rides. The newly launched e-bike by Tata-backed comes with inner-framed lithium-ion battery that can provide a range of up to 40 km by charging for 2:30-3 hours.
The high initial installation cost required for brushless DC motors is observed to hinder the growth of the global brushless DC motor market. The initial cost of a brushless DC motor is higher than a conventional motor, which may deter some customers from choosing BLDC motors. Brushless DC motors are made up of a variety of materials, including copper, steel, aluminium, and rare-earth magnets.
The cost of these raw materials can fluctuate based on supply and demand, which can impact the overall cost of the motor. Additionally, the manufacturing complexity affects the final price of the motor. This is particularly true for small applications, where the cost of the motor may be a significant portion of the overall system cost.
Brushless DC (BLDC) motors are capable of being used in robotics due to their high efficiency, high torque-to-weight ratio, and precise control capabilities. BLDC motors can be used to drive various gripper designs, such as parallel-jaw grippers, three-fingered grippers, and suction-cup grippers. According to the report published by Zippia in March 2023, about three million robots are used in industries across the globe.
At the same time, approximately 400,000 robots are set to enter the global market, with 88% of companies planning to invest in robotics for better performance. The rising deployment of robotics is observed to offer lucrative opportunities for the market players in the global brushless DC motor market.
For instance, the healthcare sector in the United States is focused on automation by deploying robotics for surgical procedures. Robotic surgery is a minimally invasive surgical procedure that uses robotic systems to perform surgical procedures. Robotic surgery provides increased precision and accuracy, reducing the risk of complications and improving patient outcomes.
