An electronically commutated motor (ECM) is a type of electric motor that combines the benefits of both AC and DC motors, offering high efficiency, reliability, and variable speed control. ECMs are brushless DC motors that are controlled electronically, rather than mechanically. Their design and electronic commutation capabilities make them suitable for a wide range of applications where energy efficiency and variable speed control are important. ECMs are increasingly becoming popular in industries, such as heating, ventilation, and air conditioning (HVAC), refrigeration, industrial automation, home appliances, and automotive

Drilling rigs are machines that are used to drill a wellbore at oil and gas reserves for the extraction of hydrocarbons. In onshore drilling, drilling rigs include virtually all components required for the drilling process. While in offshore drilling, drilling rigs include the same components as onshore drilling rigs, but not those of the drilling platforms or vessels themselves. The major components of the drilling rig include a mast or derrick, mud pumps, mud tanks, rotary tables, drillstring, draw works, power generation equipment, and other auxiliary equipment. Oil and gas upstream companies hire drilling rig contractors to drill oil and gas wells.

Energy-based aesthetic devices are medical technologies that use various forms of energy, such as light, heat, sound waves, or electromagnetic fields, to improve the appearance of the skin. These devices are commonly used in aesthetic clinics and medical spas for treatments like skin rejuvenation, wrinkle reduction, fat reduction, and hair removal.
