Hi All,
I have just acquired several Slo-Syn SS92 240V 1 Phase Synchronous motors and am a little perplexed to wiring them up. First off, they have a built in terminal block with 7 pins labeled A-H, left to right from the back.
I am using these in an automated wood mortiser/tenoner which I'm building. This is not CNC, it's automated with microswitches, etc... I'm looking to set the switches in the machine is such a way that they can be adjusted for various widths, heights and depths. One will fire the next, will fire the next in a continuous pattern until the operator overrides the cutting action.
These switches need to fire the CW and CCW directions of the motors as required. A 120V 1 Phase would be a simple wire job but I'm not too sure what to do with the 7 pins on the terminal block. I feel one pin is Chassis ground? and I feel the other 6 are actually 2 separate circuits for CW and CCW directionals? Of these circuits, one would be common, one L1 and one L2?
Danaher's (Superior Electric distributor) web site has a wiring diagram for a newer version of this motor, the KS092. It shows 2 lines coming in. One common (the motor's white wire anyway) attached to leg 2 of the motor. The other AC line attaches to a switch to control CW and CCW motion by either directing the voltage to leg 1 or leg 3 via red and black wires respectively. There is then a capacitor and a resistor (customer supplied) in parallel with these two wires. This looks like a 120V, 1 phase wire up to me. Maybe I just don't understand something here.
Am I going down the right road or am I all washed up? How do I wire these motors?
Thanks in advance for any help.
