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.

Integrated PMSM (Permanent Magnet Synchronous Motor) is a hardware design class that combines a permanent magnet synchronous motor with its drive electronics, encoder, and optionally a gearbox into a single compact unit. This approach simplifies system integration in robotic applications by reducing external components and wiring complexity. Common use cases include robot joints, exoskeletons, and mobile platforms where high power density and precise position control are essential.
