In general, it is concluded that the most commonly used electric motors are alternating current and DC. DC machines are usually more expensive and need a DC source, or a device that converts ordinary AC power to DC. This type of machine can operate at a speed that must be adjusted between high limits and conditioned to precise controls, with great flexibility. Its use is indicated in specific cases in which the needs compensate the highest value of its maintenance and installation. Thus, alternating current motors are the most sought after due to the important fact that the distribution of electric energy is carried out in alternating current.
Synchronous motors baldor VM3546T-50 have a fixed speed, which prevents slipping from interfering in any way. In this way, this machine is used for high power, for its high cost in smaller sizes. The induction operates with a constant speed, varying slightly with the mechanical load applied to its axis. Because of its ease, low cost and robustness, it is the most used engine on the market, making it ideal for all types of driven machines.
