If you can measure the voltage and amps flowing into the motor leads: (single phase) Amps x volts = VA, assume the Power factor is 0.8 so the KW is (VA/1000) x 0.8 on three phase, assuming balanced line currents, multiply by sq rt 3 (1.732). That

Shaft Pump Power. The shaft power the power required transferred from the motor to the shaft of the pump depends on the efficiency of the pump and can be calculated as. P s(kW) = P h(kW) / η (3) where . P s(kW) = shaft power (kW) η = pump efficiency. Online Pump Calculator SI-units

Amps to kW calculator * Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12. DC kilowatts to amps calculation. The current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by the voltage V in volts (V):

If you can measure the voltage and amps flowing into the motor leads: (single phase) Amps x volts = VA, assume the Power factor is 0.8 so the KW is (VA/1000) x 0.8 on three phase, assuming balanced line currents, multiply by sq rt 3 (1.732). That

Shaft Pump Power. The shaft power the power required transferred from the motor to the shaft of the pump depends on the efficiency of the pump and can be calculated as. P s(kW) = P h(kW) / η (3) where . P s(kW) = shaft power (kW) η = pump efficiency. Online Pump Calculator SI-units

Power is consumed by a pump, fan or compressor in order to move and increase the pressure of a fluid. The power requirement of the pump depends on a number of factors including the pump and motor efficiency, the differential pressure and the fluid density, viscosity and flow rate. This article provides relationships to determine the required

Motor Sizing. Proper sizing and selection of a motor for your equipment is key to ensuring performance, reliability and cost of the equipment. In addition to the information below for properly sizing a motor, Oriental Motor offers online motor sizing tools as well as assistance from our Technical Support staff.

An electrical motor with power 150 kW has power factor before improvement cosΦ = 0.75. For a required power factor after improvement cosΦ = 0.96 the capacitor correction factor is 0.58. The required KVAR capacity can be calculated as. Scientific Online Calculator . 12 20 .

The power factor correction capacitor should be connected in parallel to each phase load. The power factor calculation does not distinguish between leading and lagging power factors.

Power-Torque Torque (lb) = 63,025 x Power (HP) / Speed (RPM) Power (HP) = Torque (lb) x Speed (RPM) / 63,025. Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)

Charging Electrical Vehicles Voltage, Amps and Power EV Electrical Vehicle Charging Stations Power vs. Amps and Voltage AC vs. DS Single Phase vs. Three Phase; Electric Motors Power and Torque vs. Speed Speed of electrical motors output power and torque

Motor Efficiency is the efficiency of the motor. Brushed motor have around 75-80% efficiency and brushless motors have around 85-90% efficiency. Speed is the top speed of the calculation. This calculator provides an estimate of what size electric motor is necessary to propel a vehicle on flat ground or up an incline at a certain speed.

kW-kVA to Power factor calculation, formula, table, convert free. With this tool you can convert online from kW-kVA to Power factor automatically, easily, quickly and free. For more ease we show how to convert from kW-kVA to Power factor and show the formula that is used for the conversion and a table with the main conversions from kW-kVA to Power factor.

Angle between Supply Voltage and Load Current. The power factor always lies in a closed interval of -1 to +1. The power factor calculation can be done using a power triangle, the cosine of the angle between active power and apparent power is considered as power factor and it is same as the angle between supply voltage and load current.

In a motor, power is delivered to the load by converting electrical energy per the following laws of science. In electrical systems, voltage is the force required to move A true power calculation will work on any type of waveform regardless of the power factor Selecting Instruments for Electric Motor Power Measurement and Analysis.
