Advantages of Electric Induction Motors

An induction motor is a motor in which electric power is induced into the rotor, or the rotating part of the motor, by magnetic fields. This rotor causes the motor to generate power, or what is called energy in physics. An induction motor is usually a one to thre- phase motor, the most popular of which is the three phase motor. The three-phase induction AC motor is classified into wound rotor and a squirrel cage rotor. The induction motor usually consists of copper, aluminum and steel. An induction motor is an asynchronous motor, which means power is supplied to the rotor by the stator or the stationary part first, and then converted into torque because of the magnetic force that the stator produces in the process. The three-phase method, the motor's construction and the way power is supplied all give the electric induction motor several advantages.

Ease of Operation

Because of the three-phase induction method of producing power, induction motors are easy to operate. As a result, these motors are well-suited for large uses, such as in industries. Operation is relatively simple because the induction motor can self start. The motor can self start because there are no electrical connectors to the rotor that supply power, and current is induced by the action the transformer performs on the rotor because of the low resistance of the rotating coils. In huge industrial applications, this can result in reducing the effort needed for maintenance.

Another major advantage of induction motors is that the transformer, one of their integral parts, works only with AC motors. Its energy output can be moderated for both low and high voltage uses, ranging from 12V for household uses to up to 240V for industrial uses. This quality enables it to drastically reduce waste in electric power. The same reduction in waste can also be achieved in a DC motor, but the process is far more complicated.

Another major advantage an induction motor carries is that it is extremely rugged. This makes it the ideal machine for heavy uses. Its low cost of maintenance and durability complement its toughness, and as a result these motor can run for years on end with relatively no cost or maintenance.

Yet another advantage of electric induction motors is their ability to be connected directly to the AC source. This may not mean much in household uses, but in industrial uses, this can be an important cost saver. Since the basic electric design has graduated into an electronic one over the years, an induction motor is easy to program for its various uses. The initial cost of installing it may be a little high, but it will save money in the long term because of the low maintenance cost and durability of the product. Moreover, it is a flexible design which allows innovations and newer technologies to be incorporated easily without incurring extra costs or necessitating changes in basic design.
