Servo Motor

[Mack51]

I have a Singer 168w 101, a post machine. I am teaching myself to sew and right now I have a clutch motor and want to change to a servo. There seems to be few to choose from and having looked on e bay also. I have a budget of 200, I am retired. Need help in picking out one, any ideas. Currently I am leaning on one on e bay from S.E.W. for 139.00 and it has the S.E.W. label on the motor. Looks the same as a Reliable.

I agree with PcCox. I have bought all of my servo motors from Toledo Industrial Sewing Machines. Right now, the cream of the crop is the Family Sew FS-550 that he sells already equipped with a 50mm (2") pulley.

You'll need to do some math to get the correct new v-belt length. See if your current belt has a length designation (e.g.: M44, 42", 3L40, etc). Then measure the diameter of the current motor pulley (assuming that the motor tension adjuster is somewhere near the middle of the bolt). Divide the existing pulley diameter by 2" and whatever the result, that is how much shorter the new belt needs to be.

Example:

Your machine has a 4" pulley on the clutch motor and a 44 inch v-belt (or leather belt). The motor you are buying has a 2 inch pulley and sits about the same distance under the table, for the motor output shaft. Divide 4" by 2" = 2. The new v-belt (type 3L) would be 44 - 2 = 42 inches.

Variables are the vertical position of the motor shaft and the current position of the bracket that positions the motor and tensions the belt. If the adjuster is already at the bottom, you'll possibly need an even shorter belt and vice-verse.. This also assumes three bolts holding the motor on.
