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 »
The Pro-3200 is a next generation vibration measurement instrument for rotating equipment with anti-friction bearings. The IoT gateway serves as a secure private cloud for Real Time Monitoring, Interactive Data Collection, Diagnostic Analysis and Reporting. No subscriptions are required for cloud access. This portable device has built-in Wi-Fi and is accessible simultaneously by up to 20 mobile devices via a free mobile app for iOS and Android.
The vibration sensors can be easily located in the correct ISO-10816 positions for data collection on rotating machines to perform an analysis of live data in real time. And this device can be used on any rotating equipment (motors, pumps, air compressors or gear reducers). The Pro-3200B interactively integrates measurement, analysis, and diagnosis all in one device. Click here for a video demonstration.
Time-Frequency Selectable - The gateway provides both time-domain and frequency-domain vibration signals that are selectable via smart phones.
Replaces Typical Frequency Analyzers - Working together, the smart vibration sensors, IoT Gateway and smart phones represent a replacement of expensive and complicated Frequency Analyzers virtually anywhere, any time.
All-in-One - The Pro-3200B integrates three operations: vibration measurement, analysis and diagnosis all into one operation; moreover, the diagnosis is operated interactively, in real time.
Plug-and-Play - All operations are powered by a mobile power pack and the diagnosis is delivered via wireless Wi-Fi connections. No power cords or network wires are needed, just plug and play: amazingly easy to use.
The portable case contains an IoT (Internet of Things) gateway, smart vibration sensors and a rechargeable mobile power pack with a 12 hour battery pack. A temperature sensor is included with the Pro-3200B. The Pro-3200B is a completely portable solution for motor health diagnostics.
ONSITE INSTRUMENT USE
Measures 3-axis RMS values and compares against the motor vibration specifications
Presents the FFT data so that the vibration energy distributions on frequency domains can be reviewed and diagnosed for the four possible defects: bearing defects, misalignment, unbalance and soft foot, which are 90% of a motor’s mechanical failures.
IoT Gateway and Smart Phones work together to provide an interactive real time assessment.
Record all measured data and diagnosis results for future motor health reference
