Will this work for a singer 111w154 ?

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

[Constabulary]

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

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.
