Thisvariable frequency drivewas rated with a service life of 50,000 hours. The conveyor runs a total of 7,280 hours per year. Dividing the service life of theVFDby the total hours per year gives us 6.9 years life. The payback is 9 years. Thevariable frequency driveis expected to last just under 7 years.

MotorName plate states that whenMotoris connected in Delta its specs will be 380V and 41.3A and whenMotoris connected in Star its specs will be 660V 23.8A. So if you are using drive as star connected and 440V than your Drive rating will be as follow. Input/Output Voltage ofVFD– 380V

VFD sizing should always be based on motor current and voltage, not hp. Let’s begin with the basics by learning how to read a motor nameplate. The nameplate in Figure 1 shows that motor current is based on the input voltage: volts (V) 230/460, full load amps (FLA) 13.4/6.7.

Jul 17, 2008· Typically VFDs or Vector drives have an internal DC supply with a moderate size capacitor for filtering and absorbing some regenerative energy. What is usually done is to add a resistor connected thru a relay in parallel with the capacitor and shunt the capacitor when the …

TheMotors& Drives division offers a full range of low and medium voltagemotorsand adjustable speed drives. These products, hallmarked for quality, performance, and durability, can be customized to meet the most demanding applications.

VSD or Soft starter for Stone Crushing Machine Motors. Stone Crushing Machine Motors required high starting torque at the time of starting the motor. It is not required all the time this motors are the short time duty cycle, so Soft starter only limit the starting current to motor. The torque Compensation or the Torque Boosting function is absent in the Soft Starter.

On a normal start from empty, the VSD ramps the crusher up on a slow ramp time, restricting the absorbed current due to the high inertia of the application. This not only keeps the power supply requirements low, for a more efficient system, but also reduces the stress on the mechanical system.

For motorscontrolled by avariable frequency drive(VFD), the control method used in large part determines amotor’s efficiency and performance in an application. ... a rockcrusher’s load ...

Jul 02, 2009· In general, yourmotorwill run at 100% speed and the final speed of your stonecrusheris the ratio of yourmotorpulley and the stonecrusherpulley. By installation theVFDto your stonecrusherwith the pulleys intact, it will not serve any purpose. Some application where theVFDis usually used in is as follows: Water Pump; Fans; overhead ...

Variable Frequency Drives AVariable Frequency Driveis amotorcontrol device that protects and controls the speed of AC inductionmotors. From theVFDbasics theory, we know aVFDcan control the speed of themotorduring the start and stop cycle, as well as throughout the running cycle by outputting adjustable frequency.It also refers to as Variable Speed Drives (VSD), Adjustable Speed ...

A DCmotor VSDcan consist of a very simple circuit, which makes them generally less expensive than VSDs. VSDs control the frequency and voltage of the AC signal. Adjusting the frequency of an ACmotorcontrols its speed, while changing the voltage will change the torque provided by themotor.

Oct 03, 2018· ACmotorsare often used in equipment that runs at constant speed regardless of load, such as fans, pumps, and conveyors. But when speed control is required, an ACmotoris paired with avariable frequency drive(VFD), which regulates themotor’s speed by using one of two control methods — scalar control or vector control — to vary the frequency of the supplied voltage.

We have a 30-40 yr old portable recycling plant It has a 40'semi trailer with all switchgear in it with s/o cords running out to allmotorsWhat i ran across is this plant has a vibrating feeder feeding a Jawcrusher, so the operator stop/start feeder as needed with is often because jaw is full I think a varible feeder is the right way to do this. this operator stands on a platform by jaw and ...
