When we talk about electric Motors efficient in water pumps, we talk about the ratio of how effectively the motor converts electrical energy into mechanical energy. In this ratio, there is generally a certain amount of loss of input power, creating a difference between the two. This margin of lost power is called watt loss, and generally comes in the form of heat.
There are different types of efficiencies however, that determine how effectively a motor can convert energy from electric to mechanical. Let’s take a closer look here.
Volumetric Efficiency
Volumetric efficiency concerns itself with the ratio of the volume of fluid displaced by a piston in the motor during its operation. It is a term used to describe the operations of internal combustion density (particularly where fuel is concerned), but is not strictly exclusive to these types of motors.
Hydraulic or Mechanical Efficiency Electric Motors
The hydraulic efficiency of a motor defines the torque required to drive it. This efficiency can be measured in terms of a percentage, with higher percentages requiring less force to drive the motor. Bear in mind, however, that an efficiency of 100% is actually impossible, since this basically means that no pressure would be required for operation.
Combined Efficiency
The combined efficiency of a motor measures the combination of hydraulic efficiency and volumetric efficiency. Working out this efficiency is wise for determining how much heat energy loss is being incurred in the motor during its operation.
Typically this will be tested when a new motor of components are installed, so that one can ensure that it meets its requirements. Wherever a motor is performing fewer cycles (moving more slowly than it should), this test is also useful to see how much energy is being lost.
