Does the RPM of a motor vary if a load is added to the motor?
The speed of an electric motor is directly proportional to the frequency of supply. The rpm written on the name plate is the maximum operating speed for the motor design. Typically, for a squirrel cage induction motors, the speed is constant by design and this type of motor cannot operate for a long time at speeds below the rated value. It is true that loading affects motor speed to some extend but the electric motor will accelerate to the rated speed. If the loading is within the design parameters of the motor, the electric motor speed will not drop. What typically happens is that if the loading increases, the speed goes down, and the current increases. Because voltage is constant, this result in a high I2R loss in the windings and the motor circuit protection trips on thermal and electrical overload. The formula for electric motor speed is SRPM=(120f)/P. The above is for AC motors. If you are referring to a DC motor, what you have stated is correct. The motor will slow down as load is added. That is why you are not supposed to run many DC motors under no load conditions - they will overspeed.
What is a machine that turns mechanical energy into electrical energy?
Electric motor.
What is output of an electric motor?
An electric motor converts electrical energy to kinetic energy.
What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
Electric motor parts?
Electric motor parts are pieces of electric motors. Some examples of electric motor parts are: bearings, carbon brushes, gasket materials, pumps, soft starters, and terminal boxes.
Aspects playing a vital role in an electric motor design?
With the upcoming and advanced technology, everyone looks out for perfection. This is the time when even engineers look out for customized electric motor design, gear design, gearbox design etc for creating something worth great performance. While having a customized electric motor design, gear design, gearbox design etc, one needs to make sure what aspects play vital role in an electric motor design. Over here we will discuss more about the various facets of electric motor design and how the design plays an important part in our electronic products.Electric motors whether it is ac motors or dc motors, both come in different shapes and sizes. For routine utilization standardized electric motors are available so that these can be used for general purposes. Apart from this there are electric motor designs devised especially for specific tasks. In all the cases where electric motor design is required, it always satisfies the dynamic need of the machines on which they are applied without exceeding rated electric motor temperature. It is therefore rightly said that the electric motor design plays a very important part as the first and foremost step in electric motor selection is determining load characteristics i.e. torque and speed against time. Along with these aspects, electric motor design selection must also be a result of mission that you want to accomplish, power availability and cost.In order to initiate the design your electric motor, you can start from a small fractional horse power ac electric motor to a 200 hp ac electric motor. The best part of getting your tailor-made electric motor design is that you have the options to change any of the values from output design data to meet the requirement of your specifications. Also, with the change in any of the values, the remaining values get modified automatically, without causing any change in the output design and performance of the motor.The advantage that user reap from getting contract manufacturing of electric motor design , gear design and gearbox design is that these can be designed as per the requirement of the machine where the machine needs to be installed. Moreover, contract manufacturing of mechanical, electromechanical and electronic products offers you the ease of minimized cost. There are electric motor design contract manufacturing companies assist the clients by offering them a strategic, integrated, manufacturing and life cycle solution for the product.The electric motor designs, gear design and gearbox design etc are developed for the engineers with the motto to get high productivity. The easy to understand designs are designed with complete documentations and include extensive information on machine theory and design. All this and more, getting your mechanical, electromechanical and electronic products designed under your thumb with the design as per your need and budget requirements. Don’t lag behind with the standardized designs that do not suit your needs, go forth and seek for the one that meets your needs and requirements.[video=]
