When an electric current is applied to a conductor, a magnetic field builds around that conductor. If another conductor is in close proximity so that the building magnetic field “cuts” through that conductor, a current of equal potential is produced with flow in the opposite direction of the original current. This conductor is called the [...]
It is of the utmost importance that you understand that the AC drive does not produce any torque; it does in fact not even produce one ounce of load moving torque. All the mechanical force that moves your equipment and all of the mechanical force that is produced by the motor and drive system is [...]
If you are easily confused by the term “medium voltage AC drives“, do not feel bad, seeing as you are probably not the only one. It is usually confusing terminology because it sounds like a technical term; however, it is really only marketing driven. From zero to 600 V is called “low voltage (LV).” “Medium [...]

The real action in an AC drive system takes place in the motor. This is really where it all happens. In order to fully understand an AC drive application, it is of the utmost importance to grasp how motors use electric power.Â
All loads moved by electric motors are really moved by magnetism. The purpose of [...]
The technological side of variable speed drives has improved rapidly over the past few years due to the enhancement of the AC drive and the increased capabilities of monitoring and diagnostic systems. This resulted in AC drives becoming the choice for paper machine drive installations and rebuilds in place of the reliable DC drives.
The AC [...]
Due to the fact that brushless motors deliver an optimized torque per package size, they are used widely in various applications. Because of this, they are both  smaller in size and lighter in weight, subsequently providing a higher peak overload capacity with wider speed range capability, as well as providing a long, reliable and maintenance-free [...]
