What is a Variable Frequency Drive?
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 »

Features and Benefits

  • Pump Talk Software - The MA7200 Plus has the features that provide a complete package for pump controls. These features include both a PID control package for the motor, as well as an external PID function for a related plant process.
  • Sensorless Vector – The MA7200 Plus has precise speed and torque control for the most demanding system performance and simple setup through an auto-tuning function. It can be operated in sensorless vector or V/Hz mode to match the user’s specific application.
  • Graphical LCD Operator - The MA7200 Plus offers easily read parameters and status in plain English text on a 2 line by 20 character lighted LCD, eliminating the need to memorize parameters. Straight forward monitoring of drive status through the LCD user-friendly operator is also available, which simplifies set-up and troubleshooting.
  • Parameter Copy - No extra hardware is required on this drive. The copy feature is included as standard in the keypad. Simple cloning of the drive program is available, making it perfect for the OEM.
  • Flexible Input/ Output Options - The MA7200 Plus offers sink or source selectable digital inputs* - 4 Preset, 4 User Programmable, 16 Preset Speeds, 2 Analog Inputs, 2 Analog Outputs, 3 Multi-Function Output Contacts - 1 Form C Relay, 1 Form A Relay, and 1 Open Collector Output.
  • Two Built-in PID Control Loops - Revised Powerful Programming Options - The MA7200 Plus allows the user to set up basic parameters for simple tasks or take advantage of advanced features for demanding applications.
  • Communications - The MA7200 Plus has Modbus RTU protocol as standard. The user can control, program, and monitor the drive(s) over an industrial network. 
  • Performance - User Selectable V/F Curves + S Curves are available.
  • Motor/ Drive Systems - Pair the MA7200 Plus with a TECO-Westinghouse motor for single source reliability.
