Great tutorial. Thank-you! I work in the PCB drilling industry where extreme tolerances must be maintained. The six ton drilling machines are required to position a table (weighing several hundred pounds) to within +/- 5 microns (1 micron = 0.000039") and hold that position for 10 milliseconds before the drill bit enters the PCB. The drill bit can be as small as 0.0020" in diameter. Typical drill bits will be between 0.0079" to 0.0200" diameter. Most drilling machines use precision preloaded ball-screws driven by a DC servo. Unlike the motors in this video, the servo motor does not provide position feedback - only a velocity feedback via a tachometer. As heat builds in a ball-screw, it expands lengthwise. That expansion would cause the position feedback from the motor to be less accurate. To solve this, the position feedback is provided by an independent linear digital encoder scale with a resolution of 1 micron and a positional error of 2 microns over a length of 30 inches. The encoder scale is optical and is typically made of glass. Some machines today have evolved to linear motors - no more ball-screws!

[@gabrieldigiuseppe3106]

I fought that DC servo motors could only move up to 180 degrees, but in 8:41 we see that the animation and voice tells us that you can regulate velocity with the level of voltage input and the error signal sent by the sensing device. Which one is true then?

[@realpars]

Gabriel, servo motors are not limited to 180-degrees rotation. They are most often used to change the position if a part, rail, or robot arm, or to move a belt, chain, or piston a particular distance and/or at a particular speed. As you saw in the video, feedback mechanisms can be used in control applications to regulate speed or position. It may take many revolutions of the servo motor to position the part or move a piece from one point to another. You may be confusing "servo" with "stepper". Stepper motors are often used to rotate a mechanical piece in "steps", with a normal maximum single step of +/-180 degrees.

[@gabornyiri4868]

Nice video, but I think at 13:15 there is a missunderstanding: the rotor flux must rotate together with stator flux. They are stuck together. Lets suppose, that the speed of RMF is 3000RPM (f=50Hz, number of poles:2) and the rotor rotates with 2880RPM. The RMF of stator induces alternating current in rotor with 2Hz frequncy, that creates a second rotating field. The speed of this rotor created RMF is 120RPM compared to the rotor and 3000RPM to the stator, so they rotate together.

[@LamantinoElettronico]

If you buy a servo motor do you need a driver circuit/micro controller to operate it or is a potentiometer sufficient?

[@realpars]

If you need to control velocity, distance, or precise position, you will need to have a controller. If you just want to turn the motor on and off and vary the speed, a power supply, switch, and potentiometer is all you need.

[@eugenepohjola258]

Howdy. Nice presentation. Just one comment. Induction motors are designed to run continuously. Momentarily they can deliver about 2,6 times the nominal torque. Running continuously on over torque will smoke the stator windings quite fast actually. If suspected having run on over torque quickly disconnect the load and let the motor run idle until no more heat is blown out by the fan. One may have saved the windings but a way shorter life span should be anticipated. Servo motors are designed to run only intermittently. They are designed to deliver way more torque than induction motors. Regards.

[@realpars]

Great comments! You are absolutely correct about the type of motor versus torque. As with most equipment, the system needs to be designed to stay within the mechanical and electrical boundaries and capabilities of the equipment. A thorough understanding of the application is very important.

I work an offset printer and the servo drive operates the speed of the water roller which can be sped up or down. There are four of these on my machine, one for each coloured unit. The servo is running to slow and I can't get it to run faster. It's the same on all units. I can't print as the water roller is spinning to slowly to put enough water on the plate. Any thoughts on how I can get the servo to run faster and be controlled and adjusted manually?

[@realpars]

Servo drives are controlled by a hardware "box" or "card" which usually is configured by attaching a PC to the drive interface. In that configuration are settings that limit speed, control direction, etc. Also, every servo motor has a rated speed, which is the maximum speed at which it can run. You will need to investigate these parameters and figure out if the speed at which you would like to run is supported by the hardware and controller. I imagine there is some way to adjust the speed on a panel or HMI somewhere. If not, the servo was designed to run at a specific speed, in which case you will need to investigate changing the configuration of the device.
