Electric Motor Types
The electric motor has been around for more than a century now, as some crude designs have been created as early as the mid 1800's, however it has enhanced in performance, so that we can now find several types of electric motors on the market. This is the article where we are going to discuss about the several types of electric motors available for purchase today. You can even find used motors at decent prices, however it is better that you know exactly what you are looking for, before considering any bargain.
The first type of electric motors is the split phase motor, which is mostly used for "medium starting" applications. It has a special start and a run winding, and both are energized simultaneously when the motor is started. When the motor reaches about 75 percent of its full load speed, the starting winding is the first one disconnected by the presence of an automatic switch. This way the power remains constant through out the function time. This motor is used where stops and starts are somewhat frequent in traffic. Common applications of split phase motors include house hold or office items such as: fans, blowers, office machines and tools such as small saws or even construction drill presses, where the total load is applied after the motor has obtained its operating speed.
The second type of electric motors is the capacitor start. This type of model represents a better version of the split phase motor as it gives out a lot more energy at the stating point, and it requires less energy to start. Ideal to use for heavy loads that start harder, the capacitor start lives up to its name, handling increased capacity situations. They are generally used for strong machinery such as: compressors, pumps, machine tools, air conditioners, conveyors, blowers, fans and other hard to start applications.
In the case that you are interested to buy motors to use for vehicles, then you are interested in horsepower and RPM. These are the common electric motors encountered in the motor industry. Horsepower engines are designed to produce a certain amount of horsepower and are generally limited to a certain figure as RPM motors function on the principle of rotation per minute. The latter one starts at only a certain number of rotations per minute, the general figure being 1200 RPM.
These are three main types of electric motors, available on the market today, and I do believe they have come a long way since the mid 1800's.
