My dad has a 18 acre lake that had a drain pipe that he didn't know about until it began to leak. He found the drain end of the pipe and it is now open and draining and after lots of scuba diving with terrible visibility he finally found where it is in the lake buried under a mound of rocks...
I am having a difficult time coming up the savings figure for the following situation. I am almost certain the solution is a rate calculation involving calculus. However, it has been so long I don’t know where to start.
We have logs that degrade when not sprinkled with water. Our inventory...
I am trying to give an operator a control for moving a 25’ slide. In a past application I used an analog joystick with a frequency drive. It works ok, and once the operator gets used to the deceleration and response they can usually get close. For another application with a 36” stroke I built...
I am wondering if such a device exists. We have 5 irrigation sprinkler pumps that we need to cycle off and on every x hours. I am trying to avoid running wires to each sprinkler head and using an electric valve to turn them off and on. The sprinkler uses about 50 GPM, and the water is not...
When is a AC line filter needed or not needed? The motor is a 5 Amp 480 V servo motor on an 11Amp servo drive. There will be about 50 feet of cable between the drive an motor. The servo will be making about 1 or 2 trapezoidal moves per min. We have lots of servos, and non of them have line...
I am trying to calculate the time needed to make (accelerate, constant velocity, decelerate)a move based on weight of load, force, and time. It has been a long time since I have done this and wanted to know if anyone had a spreadsheet or application that I can check my math with.
I am trying to find a fixed displacement pump to pump lubricating oil. What I have pumps about 2 GPM, and I need something around 0.2 GPM or 12 GPH (gallons / hour) at 100 PSI or above. I am using a http://www.dmic.com gear pump. Does anyone have any recommendations of a pump to use?
Positioning with a vector drive/motor
The application is a log lift to level a log before being cut by a chainsaw. The Powerflex 70 vector drives are being controlled over Ethernet IP to a L43 compact logix. Each lift has 3 HP motor driving a gearbox and a cam. The cam is cut for constant...
I am installing a new piece of equipment in a manufacturing plant. Our usual disconnecting means on our electrical devices is to put a locking disconnect on our electrical panel. The disconnect is a 250Amp non fusible disconnect. When there is work to be done they activate the disconnect...
I am selecting a vector motor for an application, and one motor has a 1000:1 constant torque and the other is 2000:1. What does that ratio represent, and which one is better?
I have a number like 25632 that I want to move into 2 integers so 25 is in one, and 632 is in the other. This seems like a simple task, and I am probably overcomplicating it. Any suggestions?
I am using a standard motor and helical bevel gearbox in a lifting application. In order to prevent the load from back driving the gearbox when it stops I am using a break motor. It all works great. I am concerned about the life of the break motor. We are using a frequency drive to bring the...
