Is there something wrong with the old motor, or can't get a pulley for it? I'm all for new parts when doing mods, but you just need to change the pulley size to change your up speed.

Whats your runbys? At 100 fpm or less you only need 3 inches, at 138 you need roughly 4.25" of runby.

Also, with 30' of rise and it being 4 stops that’s 7.5' per floor are you sure that correct? Did someone with engineering knowledge look at this? I only ask because you said “no short floors”.
With that said if you are providing accurate information with the travel then the speed of 100fpm will be more than enough because the elevator floor to floor run is really short. You want the elevator to get up to speed when making a 1 floor trip or you could have some issues. The power needed would be my concern in NYC the for elevator electrical signoff you need motor FLA X 150%= disconnect fuse size. If you run a Canton Dry unit with a 25hp motor that’s 73FLA (73X1.5= 109.5) that right within your 115amp service but it would have to be a dry unit because a 25hp submersible motor is 82FLA and that would put you over the 115amp service.

Hope this helps but I would confirm the travel and floor stops because that’s very odd to me.

Cheers

I agree 100fpm would be fine and then the disconnect does not need 125 amp service.

Total travel is 32.5 “. It’s approximately 10’ between g and 1 then 11.5” between 1-2 and 10.9” from 2-3

The issue may be changing to a submersible motor

nyc will allow for "under rated" protection but its up to the inspector. We also have to use time delay fuses not breakers. Submersible units use more amps then a dry system. If you can up the voltage to 240V or if the building feed can handle put a 120amp breaker in.
