Drive a stepper motor with acceleration and deceleration using an Allegro driver on ATmega8

The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft rotation.Most common types of stepper motor can be bipolar or unipolar, depending on the winding. To make a stepper motor move, motor windings must be loaded in the correct order. A stepper motor move at steps, it's accuracy is usually expressed as degree per step. Microstepping is a method by witch motor accur ...

Stepper motor driver

With this circuit you can drive a unipolar stepper motor. It operates in full step mode. The AVR attiny2313 micro controller controls the pulses for the stepper motor. The pulses are amplified by the ULN2003 driver. The driver accepts 5V inputs, the output for the driver is up to 30V so you can connect an stepper motor of up to 30V if you use an external power supply. With the two push switches you can driv ...

PC stepper motor driver

With this circuit you can control two unipolair stepper motors in full step mode via the RS232 serial port of your PC. A terminal program such as Hyperterminal can be used to control the stepper motors. The stepper motors can be driven one at a time.  Features: Drives two unipolair stepper motors in full step mode Accepts commands via the serial port of your PC. Can be used with any OS that has a standard t ...

2 Bit u Stepper using microcontroller

This is the second stepper motor driver circuit I build. The first one had 4 linear current sources and got so hot it was barely usable. It had some cool leds though. When I was searching for a better schematic on the internet I couldn't find any to my linking. I did find some commercial micro steppers but they were all prohibitively expensive and had lots of electronics on a circuit board. Time to design m ...

Portescap Turbo Disc™ stepper motors use a unique magnetisation method for unparalleled stepper performance

(PRWEB) October 7, 2004 “The rotor consists of a rare earth magnet with a proprietary magnetisation method that provides much smaller step angles than conventional two-phase permanent magnet stepper motors. The unique rotor design provides a very low moment of inertia for outstanding acceleration and dynamic behaviour. Coupled with high peak speeds, this means that any incremental movement is carried out in ...
