The 9g is the actual weight of that little blue servo. 9g is a general size classification. An example of their general torque is about 2.5kg/cm. They range between 9 and like 13g of actual weight. It's considered a mini servo. The larger servo is a standard servo, again a general classification of it's size and actually has the kg/cm rating printed on it. Standard servos are about 40g of actual weight.

@goobisoft4873 2 роки тому

exactly

@PunakiviAddikti 2 роки тому

Those 9g servos are the most widely used due to their compact size, light weight and relatively high torque for their size and weight. They fit easily in almost any size of RC aircraft and cars.

@irench 2 роки тому

30+ years ago vacuum was the choice driving energy to move blend, mode, recirculate doors and flow valves in automobiles. Actuators are much the choice of engineers since about the early 90s with a mix of vacuum and actuators being found in various models of vehicles within a manufacturer's lineup. Today, I can't think of a single manufacturer that employs vacuum to carry out these functions within an HVAC. Rear climate control has become so common and is much easier to accomplish using actuators ( a servo with a specific design in mind). They've even got smart enough to make the footprint quite universal within a vehicle so that one actuator design fits the door shaft of all the locations. Current monitoring transistors give these actuators the appearance to learn their range of motion when installed. Truthfully it's the control module that learns this range I am more than reasonably certain.

@dannyl2598 Рік тому

Thank you. Great job. In the 1980s 90s servo motors like the larger one you showed were used to rotate an antenna probe in the feedhorn of large satellite dishes in order to change the polarity between horizontal and vertical. This position changed from one satellite to another so you would also adjust the skew to get the best picture.

@evi1dav3 2 роки тому

I've used them in R/C cars. Really old R/C's used 2. One for steering and one to run a mechanical speed controller for the drive motor. It moved a wiper arm that would make contact with the appropriate section to send voltage to the resistor to control speed (in a few steps, commonly 3) until it got to the full speed section which sent full voltage. They usually had a section for reverse as well. They were replaced by electronic speed controllers, typically MOSFET driven, not sure when but the mechanical ones were rarely used I got started in the mid 90's.

@hobrin4242 2 роки тому

That is fucking cool. Would the wireless reciever also get it in the variable pulse length format to directly power the servo in those old mechanical cars? If so I presume the servo angle might flicker a little bit

This was awesome. I've never seen a better in depth, but at the same time quick and concise explanation about enginneering concepts (including the visuals, be it animations or the real things (like showing the signal in the oscillscope)). I'm in 3rd year of electrical engineering, and this has beeen higly motivating, seeing that each thing that I've studied separatelly (working with oscilloscopes, doing circuits, studying the control system with the feedback (the potentiometer going into the comparator)), all coming together in this device, and understanding it well because I've understood the other concepts these past years. It was absolutely awesome, and all because a very well made video.

Servos are used in various devices that need precise movement. They're used in every RC aircraft to control the control surfaces as well as retract and deploy the landing gear. They're used in RC cars for steering and in the case of nitro engines they change the gears and control the throttle as well. Open loop servos are sometimes used in model RC submarines to control the ballast tanks. They're used in some configurations of 3D printer bed leveling sensors to deploy and retract the probe. They're also used in walking robots to control each limb.

@jozsiolah1435 Рік тому

When you remove the gears from servos, and need them for other devices, you can use the injection pin (used by doctors), to fit larger gears onto small motors. Superglue is needed, but the gears will fit perfectly on motors. This technique is needed, when you want to replace a plastic or copper gear to steel one, and the steel gear has larger hole diameter compared to the motor’s axis.

Anything that demands positioning. In HVAC, you can find some closed loop servos hooked on air dampers, however they often take 0-10V or 2-10V signals instead of pwm.

@alexwang007 5 місяців тому

Some minor mistakes, these RC servos use either a DC motor which uses a single H bridge, or PMSM which uses a three phase inverter. The circuit showcased was a inverter meant for what looks like a 2 phase stepper motor. Also the control law implemented inside such a servo is usually proportional control, or proportional-integral control. (Showcased is what seems like a bang bang control)
