Applying VFDs to existing motors | Processing Magazine

When the motor is operated with a VFD, the motor shaft speed (motor speed) decreases and will cause decreased cooling from the shaft-driven fan. If the load is a standard variable torque load, such as a fan or pump (load on the motor decreases exponentially with speed), additional cooling may not be needed.

VFD Energy Savings Calculator & Payback time estimate

The most common applications of using variable frequency drives are pumps and fans, suppose a 24/7 operate constant pressure water supply system's pump controlled by VFD may save as high as 30% electricity cost bills.

How do you size a VFD? | Flow Control Network

A VFD should never be sized solely on the hp rating of the motor. It is critical that other points be taken into account to ensure proper sizing of the VFD. Let us start with FLAs. FLAs are the amps on which the motor will draw when operating at full load and full speed. The actual measured FLA may be lower than the nameplate based on the ...

TEFC motor - Wikipedia

A Totally Enclosed, Fan-Cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. An external fan blows outside air over the frame of the motor to cool it. This motor is arguably the most commonly used motor in ordinary industrial environments.

Siemens Standard Drives Application Handbook

However, the DC motor is large, expensive and requires periodic brush maintenance. The AC induction motor is simple, low cost, reliable and widely used throughout the world. In order to control the speed of an AC induction motor a more complex controller, usually called an inverter is required.

General Purpose vs. Inverter Duty - AutomationDirect

General purpose motors have been around for many years. They are the workhorse of almost every industry. An inverter-duty motor is a much newer concept that became necessary as motors began to be driven by VFDs (inverters or AC drives). An inverter duty motor can withstand the higher voltage spikes produced by all VFDs (amplified at longer ...
