To reduce electrical consumption, use controls to adjust motor speeds or turn off motors when appropriate. For example, equipment often can run at less than full speed or be turned off completely during part of a process cycle.
How much power does electric motor consume?
Calculate the power the motor consumes while in operation. The equation is W = AV(sqrt 3) where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.
How can we increase the power of DC motor?
Clearly, the power of a DC motor depends on the torque of the coil. Since torque depends on the current and the area of the coil. Also, the magnetic field can be increased by adding a soft iron core. Hence the correct option is D.
How do you make an electric motor faster?
One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.
How many kW is a 5hp motor?
Since one electric horsepower is equal to 0.746 kilowatts, the formula to find kilowatts is to multiply electric horsepower by 0.746. For example, here’s how to convert 5 electric horsepower to kilowatts using the formula.
How much power does a 30 hp motor use?
RE: power consumption by 30 hp motor
a 30 Hp pump, if loaded to 65%, will draw 14.54kW, 8 pumps will draw 116.37kW, and in one hour that is 116 kWH.
Which motor consumes more electricity AC or DC?
The result of the power consumption of the DC motor was more efficiency than by using AC motor. The operation of the battery using DC motor is about two times longer than AC motor.
Can we increase the RPM of motor?
Yes, but with a small amount above the maximum speed under normal rated conditions. Increasing the speed can be achieved by increasing the supply frequency as the speed and frequency are directly proportional; however, there are two constraints.
How can the speed of a DC motor be controlled?
Thus, the speed of a DC motor can control in three ways: By varying the flux, and by varying the current through field winding. By varying the armature voltage, and the armature resistance. Through the supply voltage.
What are the means to increase the power of an electric motor?
The current drawn by the motor is more or less proportional to the slip. As the motor load increases, the speed will drop, the slip increases, the current and so torque increases, until it reaches the rated speed of 1440 rpm at the rated power, either 1 or 2 hp depending on the motor.
