|Name||Stepper Motor Controller (AN 488) BeMicro|
|Description||The advantage of precision control, open-loop control of the motor, self contained braking, and the absence of brushes, makes the stepper motor a convenient choice for a variety of specialized applications. Printers and plotters, disk drives, robots, CNC machines, and other precision machines are common examples where the stepper motor is used extensively. |
A stepper motor's operation can be explained by considering a series of electromagnets arranged in a circle to encapsulate a rotor made up of a magnetic material. When these solenoids, or electromagnets, are energized in sequence, the magneto motive force (MMF) developed in them interacts with the rotor and causes it to re-align to the magnetic field, thereby causing it to rotate in a clockwise or counterclockwise direction. The motor's angular displacement can be controlled by simply switching these electromagnets on or off in a fixed pattern for the desired motion of the motor.
The motor controller implemented in this design uses a MAX 10 device to govern (as you have predetermined) the performance and operation of a unipolar permanent magnet stepper motor. The design uses a few switches and buttons on the demo board to serve as the user interface. This motor controller design offers the following advantages: - Two types of control for starting and stopping the motor and selecting forward or reverse rotation: manual control (through the user interface) or automatic control (through a microcontroller). - Two modes of operation: continuous mode and step mode. - Eliminates the need for an external clock signal as all MAX 10 devices have a unique internal oscillator which is incorporated in this design.

Note: After downloading the design example, you must prepare the design template. The file you downloaded is of the form of a <project>.par file which contains a compressed version of your design files (similar to a .qar file) and metadata describing the project. The combination of this information is what constitutes a <project>.par file. In releases 16.0 or newer, you can simply double click on the <project>.par file and Quartus will launch that project.
Browse to the <project>.par file you downloaded, click next, followed by Finish, and your design template will be installed and displayed in the Project Navigator pane in Quartus.
Note: When a design is stored in the Design Store as a design template, it has been previously regression tested against the stated version of Quartus software. The regression ensures the design template passes analysis/synthesis/fitting/assembly steps in the Quartus design flow.
At the command-line, type the following command:
Once the process completes, then type:
