Single Phase Motor
Single Phase Motor: Asynchronous is a type of motor that is most often used for applications where high reliability is desired. Single phase power supplies are also commonly found in lighting and ventilation systems. Single phase distribution is frequently used in heating and air conditioning applications, with the exception of light bulbs. Single phase motors are usually more cost effective than synchronous motors. Single phase induction motors are very reliable in terms of longevity and cost, which make them the preferred choice for many applications.
AC motors work through induction. A DC input power supply is provided to the motor, which is induced by a DC magnetic field into the coils that are arranged in a linear pattern. The induction motion of the coil generates a DC voltage. This DC voltage drives a magnet, which is then connected to a load. The load is then regulated by a potentiometer, resulting in output power control.
Single phase supply works on the same principle as a DC input power supply. The main difference is that the AC motor needs only a one-step process to start working, as opposed to a synchronous motor that requires two or more steps. This means that a single phase induction motor can achieve better power control than its synchronous cousins. It is also quieter, with less strain on the motor and generator itself.
There are many different types of single phase motors available, depending on how demanding the application is. For example, the single phase motor uses a small pump, called a shaded pole motor, in order to drive the rotor. These are generally used in applications such as solar energy applications where long term power outages are common. Single phase motors also can be driven using a variable ratio displacement drive (VDR), in which case the rotor and shaft are separated but remain connected.
The shaded pole AC motor operates in a slightly different way to the pimp type. In this case, the shaded pole moves up and down on a rail attached to the pole, in order to provide an up and down motion. A motor like this is commonly used in applications where either high current capacity or large storage capacity is required. The single phase AC motor works in much the same way, providing a similar range of operation when operating in either forward or reverse motion.
Single phase AC induction motors also use a form of electromagnetic induction. These motors work by inducing a very strong electric field into a magnetic field, which in turn induces a low resistance electric field into a second metal plate. The induction process induces a motion in the metal, which causes the metal to rotate. This type of electric motors are frequently found in applications requiring torque, such as rotating heavy machines.
