Simple circuit controls stepper-motors - 8-Jan-04 Issue of EDN
Stepper motors are useful in many consumer, industrial, and military
applications. Some, such as personal-transportation systems, require precise
speed control. Stepper-motor controllers can be simple (Figure 1], but they
require a variable-frequency square wave for the clock input. The AD9833
low-power DDS (direct-digital-synthesis] IC with an on-chip, 10-bit DAC is
ideal for this task, becaus.... [Design Idea by Noel McNamara, Analog
Devices, Limerick, Ireland] |

Simple stepper Motor Controller - This design allows for very
precise control of the motor: by proper pulsing, it can be turned in very
accurate steps of set degree increments (for example, two-degree increments,
half-degree increments, etc.). They are used in printers, disk drives, and
other devices where precise positioning of the motor is necessary. There are
two basic types of stepper motors, unipolar steppers and bipolar
steppers.... |

Step Motor Controller - This Application Note describes how to implement a
compact size and high-speed interrupt driven step motor controller. Step motors are
typically used in applications like camera zoom/film feeder, fax machines, printers,
copying machines, paper feeders/ sorters and disk drives. The high performance of the
AVR controller enables the designer(app note added 3/05) |

Stepper Motor Connections - Stepper motors are available in many different
models. One of the main differences is the number of connections. That can vary from 4
to 8 wires or terminals. The oldest models, for the unipolar drives have 5 or 6
leads….(electronic circuit added 08/08/08) |

Stepper Motor Controller - Stepper motor driver that will allow you to
precisely control a unipolar stepper motor through your computer's parallel port. With
a stepper motor you can build a lot of interesting gadgets such as robots, elevator,
PCB drilling mill, camera panning system, automatic fish feeder, etc. If you have
never worked with stepper motors before you will surely have a lot of fun with this
project. ….(electronic schematic added 11/08) |

Stepper Motor Controller - The direction of rotation is determined by the
FORWARD and REVERSE switches and the motor does not take any current when a switch is
not pressed. |

Stepper Motor Driver (74194) - Probably the simplest, reversible drive
circuit is the H-Bridge. Some BEAMbots use H-bridge motor drivers; many more use an
H-bridge variant of some sort. Here's a simple conceptual schematic: Image Based on
the SN74LS194, Bidirectional Universal Shift Register the circuit is designed to drive
UNIPOLAR type stepper motors and provides only basic control functions, Forward,
Reverse, Stop and Speed adjustment. The only step angle for this driver is the design
step angle for the motor. The circuit is not complex and is cheaper than many
dedicated driver/controller devices and the parts are easy to find. ….(design added
