i have an oven fan motor and its rated at 15watts, is this output or consuption if its the output whats the efficiency, how many watts is needed to make it run at full capacity thanks i n advance
For pretty well every kind of machine, the input power is much easier to measure, for a start. Even steam engines have measurable cylinder dimensions and boiler pressure but it's anyones guess how well it will pull trucks up a hill or plough a field. 'Horse Power' used to be based more on a salesman's promise than anything else.DaveE said:Yes, it's input power in normal operation.
Motor efficiency is a measure of how well a motor converts electrical energy into mechanical energy. It is important because a more efficient motor will use less energy and save money on electricity costs.
Motor efficiency is calculated by dividing the output power (mechanical power) by the input power (electrical power) and multiplying by 100 to get a percentage. The higher the percentage, the more efficient the motor is.
The electrical "power" rating of a motor is the amount of electrical power that the motor can handle without overheating or damaging its components. It is typically measured in watts or horsepower.
The electrical "power" rating of a motor does not directly affect its efficiency. However, a motor with a higher electrical "power" rating will be able to handle heavier loads and may have a higher efficiency at those loads.
Yes, motor efficiency can be improved through regular maintenance, proper lubrication, and using high-quality parts. Additionally, choosing a motor with a higher efficiency rating can also improve overall efficiency.
