Will this work for a singer 111w154 ?

Would this work with singer 11w154 to replace the old motor?

it will but depends on your expectations regarding sewing speed. You may need a smaller pulley or speed reducer in addition.

Dam lol looking to slow it down

Best way is to fit a speed reducer pulley as well.

It will

 But you may want to find a version where the control box is separate from the motor. This way the controls can be mounted at the edge of the table where you can play with them. The style you show would require you to climb under the table to tweak any of the settings.

Yes and No. My two cents:

i) Looks like the cooling fan is incorporated in the motor pulley. So getting a smaller motor pulley with the cooling fans maybe limited.

ii) Appears to be a 550 watt 6 coil brushless servo motor which would probably work. A 12 coil 550 watt would be better but would cost more (2X).

iii) The start up speed could be as high as 500rpm which will give you startup jerk. A speed reducer would help eliminate that or go with a brushed servo motor rather then the brushless servo motor.

iv) Make sure the operating manual comes with the setup.

v) Like @AlZilla has mentioned the control box is going to be in a awful location under the table so you are going to be down on your hands and knees to change the settings.

Plug this one into the wall, and see how fast the pulley moves at its slowest setting. You can put a piece of tape on the pulley so you can count revolutions as you time it with a stopwatch. That will inform the slowness this one is capable of.

By the way, how fast is your old motor?

It takes some research but you can find cheap servos with a start speed of 100 rpms. In my case, with the small pulley and a speed reducer, I can get down to 11 stitches/minute. There's a whole rabbit trail of slow speed versus cooling. But I think at the hobby level we're not running these things for prolonged periods of time, so it's probably not a giant issue. 

11 spm is ridiculously slow.
