# Stepper Motor

## Construction operation & Types of Stepper Motor

A stepper motor’s purpose is to rotate through a precise angle and halt. The speed and torque of the rotation are secondary concerns. As long as the stepper rotates through the exact angle and stops, its mission is accomplished. Each turn is called a step, and common step angles include 30°, 15°, 7.5°, 5°, 2.5°, […]

## Stepper Motor Control

Stepper Motor Control             Because VR steppers are so scarce, this article focuses on controlling PM and HY steppers, which are almost always two-phase motors. Some PM and HY steppers are bipolar and have four wires. Others are unipolar and have five or six wires. The terms bipolar and unipolar identify how the wires are connected

## Transient Performance of Stepping Motors

Transient Performance of Stepping Motors Step Response It was pointed out earlier that the single-step response is similar to that of a damped second-order system. We can easily estimate the natural frequency ωn in rad/s from the equation Knowing ωn, we can judge what the oscillatory part of the response will look like, by assuming

## Drive Circuits and Pull Out Torque Speed Curves

Drive Circuits and Pull Out Torque Speed Curves Users often find difficulty in coming to terms with the fact that the running performance of a stepping motor depends so heavily on the type of drive circuit being used. It is therefore important to emphasise that in order to meet a specification, it will always be

## Characteristics of Stepping Motors

Characteristics of Stepping Motors Static Torque–Displacement Curves From the discussion in previous article, it should be clear that the shape of the torque–displacement curve, and in particular the peak static torque, will depend on the internal electromagnetic design of the rotor. In particular the shapes of the rotor and stator teeth, and the disposition of

## Stepping Motor

Stepping motors are attractive because they can be controlled directly by computers or microcontrollers. Their unique feature is that the output shaft rotates in a series of discrete angular intervals, or steps, one step being taken each time a command pulse is received. When a definite number of pulses has been supplied, the shaft will

## Stepper Motor Working Principle

Hi friends, In this article, I am discussing the stepper motor working principle, its basics and applications. You will find it informative and interesting. So keep reading. As the name implies, a stepper motor, within its operation range, and capability, starts, stops, reverses and moves through a predetermined stepping angle under commands from an electronic logic

## Working of Stepper Motor

Hi friends, In this article, I am discussing the “working of stepper motor“. This article will definitely increase your knowledge about stepper motors, I hope so. The stepper motors convert electrical pulses received by their excitation (control) winding into discrete angular displacements-commonly called as steps. The characteristic property of the stepper motor is the step-by-step turning of the
