A stepper Motor is basically a synchronous Motor. In stepper motor there is no brushes. This motor does not rotate continuously‚ instead it rotates in form of pluses or in discrete steps. Thats why it is called stepper motor. There are different types of motors available on the basis of steps per rotation‚ for example- 12 steps per rotation‚ 24 steps per rotation etc. We can control or operate Stepper motor with the feedback or without any feedback. A simple image of stepper motor is shown in above

Principles of operation In any electric motor‚ operation is based on simple electromagnetism. A current-carrying conductor generates a magnetic field; when this is then placed in an external magnetic field‚ it will experience a force proportional to the current in the conductor‚ and to the strength of the external magnetic field. As you are well aware of from playing with magnets as a kid‚ opposite (North and South) polarities attract‚ while like polarities (North and North‚ South and South) repel

define!) the functional unit called a motor unit. Explain the relationship between motor unit size in finely vs. coarsely controlled muscles. Explain how motor units act to establish muscle tone. What are the functions of muscle tone? Motor Unit- One motor neuron and all the muscles it innervates. Each muscle will respond to one motor nerve which contains axons that can have up to 100’s of neurons that branch into terminals that form NMJ with ONE fiber. When a motor neuron sends an action potential

Stepper Motor Introduction A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. It divides a full rotation into a number of equal steps. A stepping motor is driven by a series of electrical pulses‚ which are generated by the MCU in an NC system. Each pulse causes the motor to rotate a fraction of one revolution‚ called the step angle. The possible step angles must be consistent with the following relationship: ∝=360ns Where α = step

The automotive industry is compassed to six different manufacturers‚ General Motors‚ Ford‚ Toyota‚ Honda‚ Volkswagen and DaimlerChrylser. All six of these companies operate in the global competitive market place. Globalization in the automotive industry has moved fast or accelerated during the late 1990’s‚ because of the building of the important overseas companies and all the mergers between the companies. The specialists would to have indicated that the expansion of the foreign commerce in the

Forth to interact with the real world. We will explore how to control motors of various types (such as servomotors and stepper motors)‚ switch power to devices‚ and sense the environment. Each article will present a project that can be used to demonstrate the ideas we are going to discuss. In this first article‚ I want to lay the foundation for the future columns and discuss the use of the PC parallel port to control stepper motors. We will adopt the fantasy that we are working on some microprocessor-based

HEADING: - MOTOR CYCLE RAIN SUITS. The English poems read rain‚ rain go away come again another day‚ but with the presence of rain suits there is a possibility of reversing the poem itself. Having a ride through every possible rain conditions‚ the best part of it is obviously having a motor cycle rain suit and on the other hand to ride after the rain stops which show the cleanliness of Mother Nature just getting out of the shower. Especially in the scenario‚ in which the chances of downpour is high
