What are stepper motors good for?
Stepper motors are good for three things—positioning, speed control, and generating low-speed torque. … With their precise incremental movement, stepper motors allow excellent control of their rotational speed suitable for robotics and process automation.
Does a stepper motor need a driver?
A Stepper Motor Driver is the driver circuit that enables the stepper motor to function the way it does. For example, stepper motors require sufficient and controlled energy for phases in a precise sequence. Due to this, stepper motors are considered more advanced than the typical DC motor.
Are stepper motors AC or DC?
Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called “phases”. By energizing each phase in sequence, the motor will rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.
How do I choose a stepper motor for an application?
When selecting a stepper motor for your application, there are several factors that need to be taken into consideration:
- How will the motor be coupled to the load?
- How fast does the load need to move or accelerate?
- How much torque is required to move the load?
How do I choose a stepper?
A simple way to choose a stepper drive is to look for four things — voltage, current, microstepping, and maximum step pulse rate. Ensure that the drive can handle a wide range of current so that you can test the system at different voltage levels to fit your application.
