Gear motors are devices that combine a motor with a gear system to reduce speed and increase torque. They are commonly used in various applications, such as conveyor belts, robotics, and automated machinery, where precise movement and control are essential. By using gears, these motors can efficiently convert electrical energy into mechanical energy, making them ideal for tasks that require heavy lifting or slow, steady motion. These motors come in different types, including AC gear motors and DC gear motors, each suited for specific applications. The gear ratio determines how much the speed is reduced and how much torque is increased, allowing for customization based on the needs of the project.
