    Thanks, responders for confirming my *suspicions* ...

    50A, Single Phase

    We need to hook up a 110v, single phase, 50A fryer to a 100A, 110v/220v, single phase panel. A few flourescents will be on during the fryer's operation, but not much else. Will this cause any sort of unbalanced load? (110v, single phase, 50A - it's all we could get at the moment)

    After installing Inverter Drive, two motors now running at different speeds?

    Andy, problem solved! One of the motors had been hooked up as 440v, when it should've been set to 230v, hence the much slower movement. What is happening here?

    Thanks, Marvo. The longer section is 3 times the length of the shorter piece, 25ft to 8ft. Will check for heat difference.

    westward10, good thought. The motors are brand new. Have only been run a few times.

    Both motors are fed by the same cable. The distance from the panel via a disconnect and the Lenze controller to the first motor, located on the 25ft section is around 60ft. The distance from this 1st motor to the 8ft section motor is about 25ft. The motors came from Turkey and are identical...

    Andy, I too thought we'd be better off with two drives, but Lenze says not. They think it's a *slippage problem*. (One hell of a slippage problem, if you ask me, and obviously, I don't know a hell of a lot about this, and neither did two contractors we've had look at it. So far)

    Andy, the Mfr. says one Drive is OK for this application.

    Andy, the drive is constant torque. Mfr. says belt lengths not a problem.

    Snowhead, both motors identical, chain drive with same size sprockets, or gears. The belts moved at the same speed, loaded or not, before installing the Inverter Drive. Manufacturer says belt lengths in this case, not a factor.

    After installing Inverter Drive, two motors now running at different speeds?

    We've just put in a bread cooling conveyor system. It has two sections, 8ft, and 25ft. Each belt has its own motor, both being 3PH, 230v. Each motor draws approximately 2 Amps. We put in a 5 HP Lenze Inverter Drive to control both motors because, before installing the Drive, both belts were...
