Horsepower is a basic unit of energy output, most commonly assigned to engines, trains and other machines that exert force. The name originates in the mid-1800's, when a man named James Scott used the term in his marketing of steam engines, to help people understand the engine's power when compared to draft horses, a commonly understood measure of energy during that time. This terminology has lasted to modern times, when most modern cars have between 125 and 200 horsepower, while high performance cars have a force potential of 400 horsepower or more. One horsepower electric motors are usually used to power slow moving vehicles like tractors and other agricultural equipment, and high power tools and appliances, like table saws and pool pumps.
In addition to horsepower, electrical, mechanical and performance characteristics help decide the application options of 1 HP electric motors. Variable electrical characteristics of 1 HP electric motors include: base speed, standard voltage, phase/base frequency (Hz), service factor, design code from NEMA, insulation class, insulation system, duty cycle and thermal protection. Likewise, variable mechanical characteristics include: mounting frame size, enclosure, frame material, end bracket material, junction box material, fan guard material, lead determination, standard mounting, drive end shaft slinger, paint, bearings, grease and standard junction box assembly position. Frame material is generally a type or grade of steel, such as rolled steel or 304 stainless steel. End bracket material has a few more options, including aluminum, cast iron and 304 stainless steel. Junction boxes and fan guards may both be made of steel or 304 stainless steel. Finally, fan material may be plastic, polypropylene plastic or heat-resistant polyethylene. Examples of standard mounting options include: c-face with a removable base, rigid, c-face with a removable rigid base, c-face with a rigid base and c-face with round body. Bearings of 1 HP electric motors are usually ball bearings and grease options may include Mobil Polyrex EM and Korschun lithium-based. Variable performance characteristics include: constant torque speed range, variable torque speed range, constant horsepower speed range, temperature rise and encoder provisions.
One HP electric motors have many applications in gas and oil and mining, agriculture and agribusiness, water and wastewater, aggregate and cement, food and beverage, pharmaceutical and pulp and paper industries. One HP electric motors are able to reach all of these markets through the strength of their low-voltage capabilities.
