Power motors are electric motors that use electrical power to generate mechanical power. Power in electric motors is measured in watts where the total power depends on the ratio of the wattmeters and number of wires. This makes single-phase two-wire circuits use one measurement of voltage, wattmeter, and current. Two wattmeter power motors are mostly used in industrial applications and use three-phase wire circuits. Three wattmeters use a three-phase four-wire circuit with a fourth neutral wire. Three-phase power motors are used in commercial and industrial applications because they are more economical when used in the operation of large equipment. The power of a loaded three-phase motor is usually measured by connecting a power analyzer. The mechanical power of an electric motor is measured in its torque and speed represented as horsepower and kilowatts, respectively. The various standards that measure the power of an electric motor consider factors such as voltage and current, input power, motor speed, and torque sensors
, which are measured by current transformers
and potential transformers.When it comes to matters maintenance, repairs, and operations, talk to the experts at MRO Supply.
