Which group EC-i 40 belongs to and how it is built
The BLDC (Brushless DC) motor is widely used in robotics due to its high efficiency, long service life, low mechanical wear, and the ability to precisely control speed and torque. BLDC motors are found in robot joints, grippers, dexterous hands, cooling fans, and mobile platforms. Combined with an appropriate controller and encoder, they form the foundation of modern electric drive systems.
