Servo's & Motors

What is a servo?

A servo motor is a term used for a specific type of linear or rotary drive. A servo is actually more of a mechanism than a motor and is able to keep speed/acceleration and position constant. The motors use a rotary encoder and a controller to create a feedback system.

How does a servo motor work?

Do you want to use a servo motor but don't know how? In our project electronicsforyou.com /arduino-introductie-servo-control/">Arduino Introduction: Servo Control we tell you everything from connecting to programming servo motors!

What is a stepper?

A stepper is a brushless, synchronous electric motor, with which you can easily control the angular rotation. This can be done in steps of 1.8 or 0.9 degrees, for example. The rotating part (rotor) is made up of permanent magnets and the stator consists of electromagnets (coils).

How does a stepper motor work?

Do you want to control a stepper motor to later make a machine, a robot or even a 3D printer? In our short project for beginners electronicsforyou.com /arduino-project-stepper-motor-speed-control/">Arduino Project: Stepper motor speed control we teach you the first steps to control a stepper.

What is the difference between servo motors and stepper motors?

Servo motors are often compared to stepper motors because they can both be programmed to follow certain grades. One of the main differences is the magnification of the position control. A servo motor uses a closed magnification position control and the stepper motor uses (usually) an open magnification position control. Because of this, the accuracy of the position of a servo motor is limited. However, the servo motor is often a more cost-effective solution. Due to the lack of coils and magnets, a servo motor would be a cheaper option, but not suitable for all applications.
