Each AC motor needs the support of an efficient motor controller by an AC motor manufacturer for proper functioning. Installing the control system as mentioned above can prove to be advantageous as you can be served in a number of ways. There can be a single device or multiple devices that manage the whole functioning of the motors in a preset pattern.

Induction Motor

An efficient motor controller has multiple functionalities for multiple types of motor. AC induction motors primarily induce current into the rotor windings without being physically connected to the stator windings. The induction motor has unique electrical isolation and self-protection feature against faults. They normally comprise an equipment programmer, motor control development board, in-circuit debugger, a high-voltage motor and a three phase or 1-phase high-voltage power module. Usually, most of the industrial applications call for three-phase windings. The reason is these AC motors allow speed control (variable) and considerable power in any type of setting.

Vector Drive Motor Control

Among the extensive collection of AC motor controls, the vector drive motors can control both the voltage and the frequency in an independent way. This eventually results in low-torque turnouts. The pole-changing motor controls, suited to the synchronous AC motors whether produced by an electric furnace supplier, takes care of the pole number. This is a way to alter the number of poles in the primary winding.

Synchronous Motor Control

The synchronous motors operate at a consistent level of speed up to the full load. They cannot slip for torque production. These motors use inverter controllers to function and have a large list of functions like electro-mechanical braking, motor torque regulation, electronic power-assisted steering, and many more. You can pick them for many automotive and industrial applications to ensure high productivity for your machines.

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 coil, switched reluctance designs and moving magnets. You need to study your requirements well in order to purchase the most suitable controls for your motors. Some of the designs use encoders and resolvers to get adequate feedback regarding speed and position.

Last Word

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