Study Notes
Stepper Motors vs DC Motors
- Stepper motors are commonly used in devices that require precise control of position, such as 3D printers, CNC machines, and robotics.
- A stepper motor should be chosen over a DC motor when precise control of position and rotational speed is required.
- DC motors are preferred for applications where speed and precision are prioritized over precise control of position.
- The primary function of a stepper motor is to convert electrical pulses into precise mechanical movements.
- The main difference between a stepper motor and a DC motor is that stepper motors rotate in small, precise steps, whereas DC motors rotate continuously.
