Industrial ServoPack Yaskawa 200-230V 0.6KW servo drive Input 5.0AMPS SGDB-07ADM

Applying a VFD to a specific application is no mystery when you understand the requirements of the load. Simply put, the VFD must have ample current capability for the motor so that the motor can produce the required torque for the load. You must remember that machine torque is independent of motor speed and that load horsepower increases linearly with rpm.
VFD applications can be divided into the following individual load types.

Constant torque loads. These loads represent 90% of all general industrial machines (other than pumps and fans). Examples of these load types include general machinery, hoists, conveyors, printing presses, positive displacement pumps, some mixers and extruders, reciprocating compressors, as well as rotary compressors.

Constant horsepower loads. These loads are most often found in the machine-tool industry and center driven winder applications. Examples of constant horsepower loads include winders, coredriven reels,wheel grinders, large driller machines, lathes, planers, boring machines, and core extruders.

Traditionally, these loads were considered DC drive applications only. With high-performance flux vector VFD's now available, many DC drive applications of this type can be now handled by VFDs.

Variable torque loads. Variable torque loads are most often found in variable flow applications, such as fans and pumps. Examples of applications include fans, centrifugal blowers, centrifugal pumps, propeller pumps, turbine pumps, agitators, and axial compressors. VFDs offer the greatest opportunity for energy savings when driving these loads because horsepower varies as the cube of speed and torque varies as square of speed for these loads. For example, if the motor speed is reduced 20%, motor horsepower is reduced by a cubic relationship (.8 X .8 X .8), or 51%. As such, utilities often offer subsidies to customers investing in VFD technology for their applications. Many VFD manufactures have free software programs available for customers to calculate and document potential energy savings by using VFDs.

 

 

 

 

How do you size a VFD drive for an application and feel confident it's going to work? First, you must understand the requirements of the load. It helps also if you understand the difference between horsepower and torque. As electrical people, we tend to think of loads in horsepower ratings instead of torque ratings. When was the last time you sized something based on torque?
Thus, both torque and horsepower must be carefully examined.

Torque. Torque is an applied force that tends to produce rotation and is measured in lb-ft or lb-in. All loads have a torque requirement that must be met by the motor. The purpose of the motor is to develop enough torque to meet the requirements of the load.
Actually, torque can be thought of as "OOUMPH". The motor has to develop enough "OOUMPH" to get the load moving and keep it moving under all the conditions that may apply.

Horsepower. Horsepower (hp) is the time rate at which work is being done. One hp is the force required to lift 33,000 lbs 1 ft in 1 min. If you want to get the work done in less time, get yourself more horses!
Here are some basic equations that will help you understand the relationship between hp, torque,
and speed.

hp = (Torque x Speed)/5250 (eq. 1)
Torque = (hp x 5250)/Speed (eq. 2)
As an example, a 1-hp motor operating at 1800 rpm will develop 2.92 lb-ft of torque.

Know your load torque requirements Every load has distinct torque requirements that vary with the load's operation; these torques must be supplied by the motor via the VFD. You should have a clear understanding of these torques.

* Break-away torque: torque required to start a load in motion (typically greater than the torque required to maintain motion).
* Accelerating torque: torque required to bring the load to operating speed within a given time.
* Running torque: torque required to keep the load moving at all speeds.

* Peak torque: occasional peak torque required by the load, such as a load being dropped on a conveyor.
* Holding torque: torque required by the motor when operating as a brake, such as down hill loads and high inertia machines.
