Differences in AC Motor Controls

Every AC motor needs to be accompanied with an efficient motor controller to ensure proper functioning. Installing such a control system can prove to be advantageous as it can serve you in a number of ways. It may include a single device or a group of devices that manage the complete working of the motors in a preset manner.

These efficient motor controllers have different functionalities for different motor types. AC induction motors chiefly generate current into the rotor windings without being physically connected to the stator windings. The induction motor drives uniquely characterize electrical isolation and self-protection against faults. They usually comprise a device programmer, in-circuit debugger, motor control development board, a high voltage motor and a 3-phase or 1-phase high voltage strength module. Usually, most of the industrial applications call for three-phase windings. This is because these motors allow variable speed control and important strength in any kind of setting.

complex AC motor controllers are commonly referred to as motor drives. They balance the signal kind with the control signals. The signal kind is either analog or digital like strength and voltage signals. The controllers can also work for strength conversion, increasing the signal groups and sequencing the waveforms. You can fit in these motor drives in different types of AC motors.

The synchronous motors are those, which function at a continued level of speed up to the complete load. They do not slip in order to produce torque. These motors are pushed by inverter controllers and characterize a huge list of roles such as electro-mechanical braking, electronic strength assisted steering, motor torque regulation, and many more. You can choose them for several industrial and automotive applications, so as to ensure the highest productivity for your machines.

Among the extensive collection of AC motor controls, the vector excursion motors can control both the voltage and the frequency in an independent way. This ultimately results in low-torque turnouts. The pole changing motor controls, appropriate to the synchronous AC motors, takes care of the pole number. This is a way to alter the number of poles in the dominant winding.

Another variety of synchronous motor control includes the AC servo motor controls that make use of brushless commutation with necessary feedback. The most prevailing technologies utilize the concepts of moving wire, switched reluctance designs and moving magnets. You need to study your requirements well in order to buy the most appropriate controls for your motors. Some of the designs use encoders and resolvers to get adequate feedback regarding speed and position.

Inverter drives constitute a very shared kind of motor control system. They transform inputs in AC strength to outputs with DC strength. Again, if you require motor controls with very high frequency, then you can choose from a wide range of high frequency drives. These drives are used to supply strength to the AC motors at significantly high frequency, as compared to the shared strength applications. You can also opt for the variable speed drives that serve you by adjusting and controlling the speeds of your motors.
