AC Motor Use
An AC Motor is an electrical motor powered by an alternating current (DC). The AC motor usually consists of a number of main components, namely: an outer stator, usually made of copper or some other metal; an internal rotor which turns the second part of the AC motor, called the output shaft, alternately; and a number of findings connecting the stator and the output shaft. AC motors are used in many different kinds of machines such as cars, steam turbines, electronic motors, generators and even medical equipment. AC motors have an advantage over their electric-powered counterparts in that they are silent and use less energy.
An AC Motor works in a rather simple way: It begins with the generator or engine turning the AC motor winding to create a high voltage current. A short circuit is created in the motor's main switchgear and this causes the high voltage current to split into a positive and negative current. This current is then sent through the main solenoid to regulate the speed of the motor. In order to change the speed of the AC Motor, the motor's drive gear changes the speed of the winding. The drive gear can be set for a maximum and minimum speed, or to constantly accelerate or decelerate depending on how the machine's workload requires. AC Motors usually has an input signal to control the speed of the AC Motor, as well as output signals to control the speed of the motor itself.
The output of an AC Motor can be changed in various ways: Either by externally controlling the speed of rotation of the AC Motor or via a variable resistor. External controls can range from a simple potentiometer to a device such as a tuning fork that continuously measures and adjusts the speed of the AC Motor. Variable resistors can also be used, but these require an external power source and need to be of suitable size to fit into the motor's output holes. A common type of variable resistor is the 0.1 ohm one stage unit. One thing to note: All these resistors have a specified minimum voltage; you must ensure that this voltage is met by your chosen resistance.
