Nidec Motors
Motors from Nidec Motor Corporation are known worldwide for their performance and innovation. They might also be the most diversified with respect to the number of different types including pump motors, commercial motors and industrial motors. Their AC electric motors come in single phase and three phase and can handle everything from sever duty to hazardous location applications.
Another area that the Nidec corporation emphasizes is integrating even more advanced technology into their motor designs. Motors that Nidec produces often have built-in sensors and control systems. These motors can thus operate in a kind of "closed loop" mode, where they not only receive electronic commands to "go to a certain position" or "operate at a certain speed," but can also send back electronic confirmation that they have done what they were told to do. What's more, they can also send back a stream of information about their current condition in case there is a further need to alter the commands they are receiving.
Nidec motors' durability and reliability are their most notable strong points. They are designed to hold up under not only a wide range of temperatures but also in high-dust and high-moisture environments. And, of course, in order for them to do that, they must also be properly maintained. The long life promised by the robust overall design of these motors is even longer when proper maintenance is done.

FAQs
What Nidec motor would provide the most efficiency in a water treatment company?
A Nidec brushless DC motor would provide the most efficiency in a water treatment company due to its high energy efficiency, low maintenance requirements, and precise control capabilities.
Motor Starters, Soft Starters & VFDs
Motor Starters
Motor starters safely start and stop a motor in industrial applications. They are designed with a contactor, overload and circuit protection. They are used when basic motor control is required, where torque on the motor is not a concern and speed control is not needed. The advantages of motor starters include: lower cost, allows for remote operation, allows for monitoring of motor state (with the use of auxiliary contacts) and they are safe and efficient. The disadvantages include: high inrush current that can cause fuses to blow and breakers to trip if the inrush is too high, and the starter will allow a full torque to start the motor which can cause the motor to ramp up to full speed very quickly potentially causing the motor to wear and degrade prematurely.
Soft Starters
Soft starters protect motors from inrush current by gently ramping up the motor to full speed. They provide all of the same functions as a traditional motor starter. The advantages of soft starters include: they are less expensive than a VFD when only startup control is needed, they are a smaller system than a VFD where space is a concern and they prevent unwanted torque upon startup, prolonging the life of the motor. The disadvantages include: they are more expensive than a traditional motor starter and they do not allow for full speed control.
Variable Frequency Drives (VFDs)
Variable Frequency Drives (VFDs) allow for the slow ramp up of a motor during startup and the slowing down of the motor during shutdown. They also allow for full speed control during the entire run cycle of the motor. VFDs provide the same functions as both the traditional motor starters and soft starters. The advantages of VFDs include: full speed control (start, stop and in-between), more custom control and monitoring, energy savings due to efficient motor usage and less wear and tear on the motors. The disadvantages include: they are more expensive and larger than other motor control options and they generate heat that may require fans or AC units.
