A brushless DC motor (BLDC motor or BL motor) is a synchronous motor that runs on a direct current (DC). It employs an electronic controller to provide DC currents to the motor windings, creating magnetic fields that follow the permanent magnet rotor. For speed and torque control, the controller changes the phase and amplitude of DC pulses. This control method replaces the mechanical commutator (brushes) in most electric motors.
The global brushless DC motors market is expected to grow at a CAGR of 5% during the forecast period (2017–2030).
BLDC motors are preferred in medical equipment design and other applications due to their durability, reliability, efficiency, and compactness. Global demand for medical analysis and testing services drives the development of high-throughput, reliable medical analysis, and testing technology. BLDC motors do this by delivering strong torque across a wide speed range and high duty cycle.
BLDC motors are utilized in medical equipment such as Positive Airway Pressure respirators, fluid analysis machines, elevators, patient beds and blowers, compressors, surgical equipment, and oxygen concentration and generation equipment. In 2019, in the US, Germany, Switzerland, Norway, the Netherlands, etc., the healthcare expenditure was high. It boosted the demand for BLDC motors in healthcare. The Centers for Medicare and Medicaid Services report that hospital spending increased 6.2% in 2019 compared to 4.2% in 2018.
Brushless motor producers face high-cost restrictions owing to the motor and electronics. Since BLDC motors are difficult to build, they are often 30% more costly. A switching controller is needed for BLDC motors to charge the stator coil properly. It features coils within the stator instead of an armature. Most tiny in-runner windings must be fitted by hand. This makes it more costly than machine wound brushed motors.
Miniature motors are employed in many sectors due to their enhanced accuracy, smaller size, and higher efficiency. The increased demand for automation drives the demand for small motors. Collaboration robots have also boosted the demand for micro motors. Small motors are required for robotic arms, pick and place grippers, humanoid robots, and prosthetic arms.
Furthermore, combining artificial intelligence with collaborative robots should improve the technology-driven future. Workers are less injured and safer while using COBOTs. COBOT manufacturing has expanded in response to the fourth industrial revolution's desire for automation. To fulfill the increased demand, Doosan Robotics unveiled six new COBOTs on July 29, 2020. As demand for COBOTs grows, so will the need for small BLDC motors.
As a result of the COVID-19, businesses, including aerospace and food and beverage, have ceased output. Government-mandated precautions like social isolation and partial or total lockdown harmed the market. In the global aerospace and defense industry, the COVID-19 pandemic has disrupted OEMs in commercial aviation and faced less demand, fewer labor, and travel delays.
Airlines in America reported a 68% drop in commercial airline passenger numbers from September 2019. It has put airlines, manufacturers, supply chains, airports, and the tourism sector at risk. According to the International Air Transport Association, global airlines lost more than three times during the GFC.
BLDC motors are divided into two categories based on their shape: cylindrical and flat/pancake. In general, cylindrical-shaped motors are more widely utilized in various applications than flat-shaped motors, and they held the largest market share in 2021.
The market is divided into five segments based on application: aerospace and military, outerspace, medical and life science, food and beverage, robotics, and others. The medical and life sciences had the greatest market share in 2021. Consumers drive the healthcare business, and their requirements drive innovation in health-related products, services, and goods. The United States is still the world's largest medical device market, and it will continue to be so.
In 2017, the US market accounted for over 40% of the global medical device market. In 2020, the European medical technology industry was worth over USD 158 billion. Germany, France, the United Kingdom, Italy, and Spain are among them. Germany had the biggest proportion of 25.6%, followed by France, the United Kingdom, Italy, Spain, and other countries.
Asia-Pacific was the largest regional market for BLDC motors in 2020, with a market share of roughly 48%. The Asia-Pacific brushless DC motor market is predicted to grow rapidly due to industrialization in India, China, South Korea, Japan, and Australia. It is also a manufacturing center for electronic components. Taiwan's electronics sector is booming, driving demand for BLDC motors.
America's aerospace and defense industries are likely to develop faster than Europe's. NASA and several firms like SpaceX are working on space exploration initiatives to enhance BLDC motor demand. Some of NASA's space exploration programs, such as DaVinci and Viper, are likely to boost the BLDC industry. Also, the North American service market is expanding rapidly. Nurses, physicians, and other healthcare professionals rely on service robots. According to the Robotic Industries Association (RIA), North American robotic unit sales grew 3.5% in 2020 over 2019.
Major players in the global brushless DC motors market are Maxon Group, Faulhaber, Moog Inc., WITTENSTEIN SE, Allied Motion, AMETEK Advanced Motion Solution, MTI Montevideo, AVEOX, ElectroCraft Ltd., ThinGap, Fulling Motor, MOONS, among others.
