Micro-motors are tiny devices that convert electrical energy into mechanical motion. They are often used in applications where space is limited, such as in medical devices, robotics, and consumer electronics. These motors can be as small as a few millimeters in size, making them ideal for precise movements in compact environments. These motors come in various types, including DC motors, stepper motors, and brushless motors. Each type has its own advantages, such as efficiency and control, allowing them to be tailored for specific tasks. Micro-motors play a crucial role in advancing technology by enabling intricate designs and functionalities.
