Wiring a single phase motor switch

Wiring a single phase motor switch

(OP)
It is my first time wiring a motor, and I'd like to avoid frying it (or myself). I'll outline the equipment and a description of wiring, followed by my questions to make this easier to digest.

EQUIPIMENT.
Motor: Make: SPG Model: 9I60GE( )CE Specs: 60 Watt Class B 115 V (60sPHz) variable speed _ motor. The motor requires 1.1 Amps.
Controller: SPG SRE series controller. Make: SPG Model: SRE02 Specs: 115 AC, includes a 12 uf capacitor of the appropriate voltage (greater than 1.5 times that of the motors requirements).
Power Supply: Black, White, Green. Supplying Voltage from a wall socket in the US (110-120 VAC).

WIRING:
Exactly the same as on page 181 of this manual, Diagram 1-1: http://www.famotor.com/data/spg/motor/standard_ac[1].pdf
This diagram is for a 125 VAC controller, but is identical to that in the manual that came with my controller.

QUESTIONS:
1. Where should I connect ground? There does not appear to be a grounding plate on the motor itself. Does it go to 11 in the diagram?

2. The switch confuses me the most. This wiring is for a variable speed, single direction application. I have a SPDT switch (one more output than needed, I know). With its three prongs, should I solder 'live' from the power supply to the center prong, and solder a black wire out of one of the three prongs into port 1 (see diagram, port 1 connects to the motors black wire)? Or should I connect it to port 2?
I cannot tell for sure, but it seems that the diagram is written for a DC input, and the sin wave represents conversion to AC. If this is true, I am assuming that the white wire bypasses the switch and goes directly to port 1 or 2 (opposite of the black).

RE: Wiring a single phase motor switch

Your link is broken and comes up with what appears to be a "404" message in Korean characters.

You picked a doozey of a motor supplier though, very difficult to get info on their products. Are you really sure you want to use this? A little sleuthing at I was able to find this on their Korean site, its a download link of the instructions for the controller, which includes the motor wiring too.
SR type speed controller
SRC type speed controller

But these will download the pdf files without putting the .pdf on the end for some reason, so you must then navigate to where your browser stored them and rename them by adding ".pdf" to the end of the strings. Then when you double click, it will open it with Adobe.

Looks to me as though they have no provisions for grounding this motor directly. If you have one and the case appears to be something non-metallic, they may consider this to be "double insulated", meaning it doesn't need a ground connection for safety. If it is a metal case, I wouldn't use it. There doesn't appear to be a UL or CSA listing on it either, a sign of trouble in that it generally means it was unable to pass, or they just don't care about selling it in North America, which would make it odd that they make a 115V 60Hz model at all then.

The SR controller is on an 8 pin socket on the manual I found, so there is no "pin 11". The one that does show an 11 pin socket is the SRCE version and it does show pin 11 as the ground for the source, but nothing about the motor. MAYBE it grounds the motor through something else, again, no way to know. I may have the wrong one altogether though, it's so difficult to navigate through their stuff that I'm not sure.

RE: Wiring a single phase motor switch

1. Ground goes to terminal 11 and to the motor frame. There may be a spare screw in the terminal box for a ground wire or you may connect the ground to the motor frame.
2. The proper switch is a double pole, single throw switch. Get the proper switch and wire it as per the diagram.
Hi Jeff. If you click on the link, and when you get the Japanese 404 error, manually add [1].pdf to the end of the url it goes to the correct manual.
Then go to page 181 or 182.
This site is for professionals and this thread may disappear shortly.
