A Simple Design: This device is made from 3 windings in the outside area with a simple turning section, called the blades. The AC line voltage induces the blades to rotate around the center. Its speed depends on only 3 points: the fixed number of poles, or electro-magnetic winding collections, constructed into the electric motor; changeable rate drives, frequently known as inverters or amplifiers, that change the regularity of the Air Conditioning line voltage; as well as the amount of force or load on the device. Modifications in speed are expected when the tons changes.
Speed Control: With this kind of device, handling the speed is simple. The greater the armature voltage, the faster the turning, meanings a faster rate. The voltage will raise combined with the horse power. Most DC commercial electric motors will perform more than a rate stove of 20:1, to approximately 5 % to 7 % of the base rate. They are made with changeable rate operation in mind, so they have heat command includes that permit much lower operating speeds.
