More Info About Stepper Motor

Stepper motor
Stepper motor is an electric motor that can be precisely controlled by signals from a computer. The stepper motor turns through a precise angle each time it receives a signal pulse from the computer. By varying the rate at which signal pulses are produced, the stepper motor can be run at different speeds or be turned through an exact angle and then stopped. Switching circuits can be constructed to allow the computer to reverse the direction of the stepper motor.

By combining two or more motors, complex movement control becomes possible. For example, if stepper motors are used to power the wheels of a small vehicle, a computer can manoeuvre the vehicle in any direction.

Stepper motors are commonly used in small-scale applications where computer-controlled movement is required. They are often used inside dot-matrix and ink-jet printers, to control both the feeding of the paper and the movement of the print head across the page. In larger applications, where greater power is necessary, pneumatic or hydraulic systems are usually preferred.

It's amazing how many applications the simple stepper motor can have. Floppy disk drives are one major use of the technology, as well as the printers you have already mentioned.

hey ,
can anyone tell me what should be the minimum time difference between two step inputs?
and which driver ic is better to drive bipolar stepper motor with the load of 2kg having specification 600mA?
