The input is connected to a dc motor which will drive the gears. We have the output and on the other side we have the input. We first find a number of gears and these are supported by some bearings on one side. We can connect various attachments to this to make use of the rotation inside the unit. On the top, we find a small splined gear. The brown wire is the ground, and the orange wire is the pulse width. In this case, the red wire is the positive voltage wire. When we look at a servo motor, we see the main housing with the electrical connections entering the side. We measure this rotation in seconds taken per 60 degrees of rotation, the physical size of the servo motor increases with the torque rating thats, because it needs larger gears and a larger electrical motor to achieve this lets look inside one to see the main parts and understand How it works by the way we have also covered stepper motors and dc motors previously do check them out links down below. The higher the voltage applied, the faster the motor will rotate. The motor consumes more power when moving it uses very little to hold its position. When the motor stalls we can see the current dramatically increases, the operating current depends on the load applied as well as the voltage. The higher the voltage applied, the higher the torque will be so the stronger the motor will perform, but as we can see, the motor has limits and it will stall if it exceeds these limits. In this example, we see it can be connected to a supplier of between 4.8 and 7.2 volts. We can find more information on the data sheet. What does this mean? Well, for example, this servo motor is rated for 25 kilograms, so at one centimeter from the shaft it can support 25 kilograms, but at two centimeters it can only support 12.5 kilograms and at three centimeters it can only support 6.25 kilograms. We normally find this measured in kilogram centimeters or ounce inches. This is how much force the servo motor can apply to a lever. This larger one has a rating of 25 kilograms. This small motor has a rating of 9 grams. This is not the weight of the motor, it represents the torque of the motor or how much force it can apply. So we will focus on this type in this video on the side of the servo motor, we usually find a weight value. Loop type closed loop provides the best control and these are more commonly used. Some servo motors will not have this and are able to rotate the full 360 degrees. Loop type theres, usually a pin inside to physically stop the motor rotating further. Instead, these are sent signals which tell the motor exactly how far to rotate typically the motor will rotate just 180 degrees, but we can get smaller or larger values. Usually, when we connect a dc motor to a power supply, it just rotates constantly, but a servo motor is different. We control the position of a servo motor by using a controller, so we often find it used in robotics and automation and even for the steering of remote control. This type of motor is used for precise control and we can connect different attachments to achieve this. It converts electrical energy into mechanical energy. They offer a 30 day money back guarantee, so do check them out ill leave a link for you in the video description down below a servo motor, looks something like this.
