What The Differences Between Stepper Motors And Servo Motors

In this video, it shows the stepper motor and servo motor's works.

What is the difference between the servo motor and stepper motor?

1)Different control precision

The precision of the servo motor is higher than the stepper motor .

2)Low frequency characteristics is different

Stepper motor is easy to appear appear low frequency vibration phenomenon at low speed.

Ac servo motor runs smoothly,no vibration phenomenon even in the low speed

3) Torque Frequency are different .

The output torque of the stepper motor will decrease with the speed , and at a higher speed will drop sharply

The servo motor will not appear this phenomenon .

4) The different overload capacity

Stepper motor will not have overload ability . Servo motor has a strong ability of overload

5)Running performance is different

The control performance of the Servo is more reliable than the stepper motor .

6) Different speed response performance

The Speed of the servo system performance is better than the stepper .

Ok, i think i got it. Servo is more like "WEEHAAO", whereas a stepper is closer to

A few notes on this:
First of all the stepper must be set with far below it's power limit as it is very hard to turn most NEMA23 steppers by hand when they are engaged.

Second the problem of lost steps and very poor speed occurs on cheap open loop stepper (meaning without a control circuit that knows whether it moved correctly). Closed loop steppers are still a little cheaper than servos, move faster and more precisely than simple steppers. Servos are basically "normal motors" with a closed loop circuit which is why they can spin a lot faster than steppers but offer less holding torque (they can only correct an unwanted movement but not told a position without some slack).

What does that mean what's the benefit of each system? If you need fast movement (above 600-1000rpm) use a servo. If you don't need fast movement but need to hold a position with high torque and no wiggle at all then maybe a closed loop stepper is an affordable option.
That said modern servos are great and in most applications they do a superb job while being cheap enough to skip cheap steppers.

Hi can u share the details of the servo motor and stepper motor part number and model

[makian_real]

There are closed loop steppers which can keep track of position (the drivers do that)

I always like crisp and clear content in one liners rather than explaining the bullshit in paragraph.😊
