Electric Forklift Engines – <\/strong>Electric forklifts are an ideal solution for indoor application, particularly in more hygienic or sensitive applications such as the pharmaceutical, food and beverage industries. Compact, unobtrusive and highly maneuverable, these forklifts are purpose built for operations in and around large facilities such as warehouses, factories and manufacturing plants.<\/p>

History of Electric Forklift Engines<\/h2>

Motors find the most practical use in our every day life in form of modern gadgets, devices and appliances. There is no exact date that can be traced back to being the exact day of modern day motor invention. It has been a gradual process with many prominent names and contributions from the scientific world. Starting way back, today we have progressed to develop nanoelectromechanical systems that promise to be the future miniature form of motors.<\/p>

The core function of electric motors is to convert electrical current into mechanical force. The history of motors <\/a>can be related to times when fundamentals of electromagnetic induction were introduced. In early 1800, three popular scientists Oersted, Faraday and Gauss came up with the basic principals of electromagnetic induction.<\/p>

In 1820, Andre Ampere and Hans Oersted made the most fascinating invention. They discovered that electric current produces magnetic field leading to the invention of the basic DC motor some ten years later. No body in particular is acclaimed with the sole invention of the DC motor, as it was a gradual process with involvement of many people<\/p>

Michael Faraday from England set to prove the theory proposed by Ampere and Oersted. In 1921, he successfully demonstrated in his experiment by converting electrical energy into motion. His motor was made of a free-hanging wire that was plunged into a puddle of mercury. A permanent magnet was placed in the centre of the mercury pool. On passing through the wire, it rotated around the magnet. It proved that the current resulted in a circular magnetic field around the wire. This is the simplest form of electric motor.<\/p>

Ten years later, it was Joseph Henry who built an improved motor based upon Faraday\u2019s experimental motor. He constructed a device whose rotating part was an electromagnet with a horizontal axis. The motion resulted in two vertical permanent magnets, alternately attracted and repelled at end of the electromagnet. This made the magnet sway back and forth at 75 cycles per minute.<\/p>

Till this stage, use of electromagnetic field in motors was restricted to lab experiments. A major development took place with William Sturgeon\u2019s invention of commutator. He is credited with the discovery of first rotary electric motor. Sturgeon made use of horseshoe electromagnets to build rotating and stationary magnetic fields. His shunt wound DC motor was the first to produce a continuous rotary motion using all essentials of modern-day DC motors.<\/p>

Another early electric motor design used a reciprocating plunger inside a switched solenoid; an electromagnetic version of a two-stroke internal combustion engine. A remarkable fact points that the modern day version of motor was actually an accident. In the year 1873, Z\u00e9nobe Gramme accidentally linked a spinning dynamo to a similar unit, driving it as a motor.<\/p>

The accident proved to be successful. And the journey of development started from then on. There are many amusing facts and chapters in the development of the present day motor. Motor is the core of many hi-tech electronic, electro-mechanical and electrical gadgets all over the world.<\/p>

How Motors Work<\/h2>

After reflecting upon the brief history of Electric Forklift Engines motors, we can shift our focus to its operations. How do motors work? It helps to understand that the basic principle of electric motor is based upon electromagnetic induction. To put it simply, motors use electromagnetic fields to generate motion. Electric motors function on the principle of magnetism\u2014 like poles repel, and opposite poles attract. The direction of current flow can be changed in one of two ways.<\/p>

Magnets and magnetism is the base for any motor to work. At large motors are of two types- DC and AC. In a basic DC motor, there is a fixed magnet on the outside called the field magnet and inside lies an armature that carries current. As soon as the current passes through the wired armature, it turns into an electromagnet with opposite polarity as of the field magnet. This repulsion causes the armature to rotate.<\/p>

So, we need to create a perpetual opposing magnetic field between the axel and the field magnet. Generally the armature is nothing but a piece of a good conductor with copper wire coiled over it. When current passes through the armature, it turns into an electromagnet and the repulsion causes it to rotate. Here, we reach a situation where after half rotation the electromagnet gets stuck as the opposite poles attract each other. To overcome this, one would need to flip the current in order to obtain perpetual opposite magnetic poles. This is achieved with use of commutator and brushes.<\/p>

Commutator is attached to the axle of the electromagnet, so that they spin along with the magnet. The brushes are just two pieces of springy metal or carbon that make contact with the contacts of the commutator. The key is that as soon as the armature passes over the maximum flux of the field magnet, the poles of the electromagnet must flip.\u00a0<\/p>

Because of the flip, the North Pole of the electromagnet is always in line with North Pole of field magnet that keeps the armature under constant repulsion. Up till now, we have been talking about bipolar motors. These motors can get stuck if after halting, the commutators are not in contact with the brushes. This demanded more than two poles in an armature and the motors henceforth should have many poles to suit various power and RPM requirements.<\/p>

The AC motors on the other hand have the advantage of auto-change of polarity due to alternating current. The electric motors run smoothly at the frequency of the sine wave and are also called synchronous motor. Most common AC motors are induction type. This means that no current passes through the armature coils and electric current is induced in the rotating coils rather than being supplied to them directly. An induction motor must achieve a rotating magnetic field to continue to exert a torque on the armature coils, while extra coils on the pole pieces achieve the rotating field.<\/p>

This explains the way motors work and the cause of rotation. Based upon these basic principle, the motors have evolved and come a long way. The modern-day motors are much lighter, cost-efficient and productive. Right from microwave ovens, furnace blowers, fans, screwdrivers to radio antennas\u2014motors are used almost everywhere.<\/p>

Types of Motors<\/h2>

Electric Forklift Engines motors are practically used everywhere round us. Starting with your kitchen fan, microwave oven, refrigerator, vacuum cleaners, hair dryers to car heaters and radiators, everything uses a motor. Following are the main types of motors,<\/p>

AC Motor<\/strong><\/p>

There are two main types of Electric Forklift Engines AC motors. The most popular and simple motor is the three-phase AC induction motor. It is also known as the squirrel cage motor. The synchronous motor rotates at exactly the supply frequency or submultiples of the supply frequency. A typical AC motor consists of two parts:<\/p>
