need speed

[Rainman229]

is there anyway to speed up the spindle speed on the bridgemill? and is it adviceable?

[Rainman229]

i guess my best bet would be to change out the stock motor to a 2hp with 3450 rmp verse the stock motor being 1hp with 1750 rpm. that should give me more speed then i need.

this a 3phase motor? if you get a vfd you can push it some more.

[Rainman229]

i'm running single phase. my setup is in a house and getting 3 phase is almost in possible.

maybe you could put a dc motor on it.

that would be nice. but it would probably be cheaper to go 110/220v the motor i was looking at was arround $90 for an unsealed motor with Ballbearings and 168 for a sealed motor w/ bb

[motomitch1]

adjustable speed controller would make it nice

[motomitch1]

heres a guy with a nice setup for $60.

Good DC motor and drive

Do you have 220 1phase? if so most vfd input 1phase power and put out 3phase. then you can get any 3 phase motor on surpluscenter or surplus store around you. some vfd will even input 120 for lower hp but they cost alot unless you find a sale :P

goodluck on the setup.

Sendkeys has the right idea. Its also good to know that most VFD's are derated when running off single phase. That means, you'd need a 3hp rated VFD to run a 2hp 3phase motor.

[Rainman229]

i thought of that but the cost of it is the issues on that.

to an who have interest
I converted my mill to VFD

from www.dealerselectric.com I got
fm100-100-202-n1
2hp 1800rmp G585 motor (240/460 in(SF 1.15)

other things needed
new Pulley mine 5.3" / new 20amp circuit / service dissconnect 30a with 15a fuses

at least #12 form the service disconnect, at least #14 from controller to motor (these are only as a reference--- see an electrictican

sheiled wire form the controller to your old pushbuttons

the biggest killers of VFD's are oil and dust build up

the FM100 does not derate the motor

Henry at dealers can help with base settings and help you pick out the right motor and controller combo

Steve and Bill from teco are VERY helpfull

after a bunch of settings I can now put in the RPM I want and the spindle spins to the correct RPM about 200-3250

It will go higher but shoptask says 4k max

software for this unit comes with the rs-232 kit (dos)

there is a 7200 model that had windows real time sotware rS485 only

I opted to the remote panel kit (3 meter) this lets you relocate the op panel from the controller

be ready to drill a couple of new holes for the motor
I put the motor in about the same place
I ran 1 belt from motor to Idler to drive pulley

the shoptaks Is Very quite with the 3 Phase motor,
running 3250 is still more quite the the stock motor setup at any speed

next will be a external emergency stop

hope this will be of interest to some

prices motor and controller $425.00 remote kit $80.00, steel pulley $50.00
