A variable frequency drive is an electronic device that allows you to start, stop, and control the speed of a three phase motor. It is also a motor starter as it is equipped with overload protection. Read more »
What is the difference between a 'new surplus' motor and a 'factory new' motor?
Our New Surplus electric motors and drives are new and unused overstock or discontinued items offered at lower prices and come with our 90-day warranty.
Factory New products are competitively priced and come with a manufacturers warranty.
Variable frequency drives (VFDs or inverters) now play an important part in major industry.
Within the last 10 years they have been perfected to control and vary the speed of 3 phase electric motors. They serve many purposes, besides speed control. Homeowners and hobbyist alike, who have lathes or milling machines with a 3 phase motor, usually don't have 3 phase power to operate. These VFDs (instead of using a rotary phase converter) can now be used to convert single phase power to 3 phase power. Read more »
Combining convenience and innovation, the SSW900 is the right choice for a complete motor protection and start/stop control. Developed for industrial use, the new line of soft-starters allows easy and simple access to the configuration settings and application data. Using a well-structured menu interface, the SSW900 line provides an unprecedented experience of interactivity with the user, allowing adjustments and configurations with online parameter help right on the Keypad. In addition, event logs with date and time & set up assistant are available. All models of SSW900 soft starter have built in AC1 bypass, which contributes to extending the life of the soft starter, optimizing space, and reducing heat dissipation inside electric panels.
