10 hp electric motor dc

    • What is the horsepower rating of an electric motor?

      The horsepower used for electrical machines is defined as exactly 746 W. In the US, nameplates on electrical motors show their power output in hp, not their power input. Outside the United States watts or kilowatts are generally used for electric motor ratings and in such usage it is the output power that is stated.

    • What is the RPM of an electric motor?

      A two “pole” synchronous motors will run at 3600 RPM; where as a two pole squirrel cage will rotate at about 3450 RPM. Different electric motor manufactures allow slightly different amounts of slip. As the number of poles within a motor increase, the speed of the motor will decrease.

    • What is 10 hp?

      Hp(10) and Hp(0.07) are personal dose equivalents, which represent the probability of stochastic health effects from radiation. Hp(10) is the deep dose equivalent. It is the equivalent dose at 10 mm below a specified point of the body.

    • What is the history of electric motors?

      1834 - Thomas Davenport of Vermont developed the first real electric motor ('real' meaning powerful enough to do a task) although Joseph Henry and Michael Faraday created early motion devices using electromagnetic fields. The early "motors" created spinning disks or levers that rocked back and forth.

      https://info.5y1.org/10-hp-electric-motor-dc_1_8949b7.html

      Reasons to Determine Motor Loading Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load.
