Hey guys whats up,im sorry for putting this here if this is the wrong forum for such a question...please tell me and i will correct asap
i was wondering if one of you gurus out there an help me out..lots of dudes here with invaluable amounts of knowledge.
i have selected a tread mill motor for a very simple lathe project and possibly the foundation of a simple mill.
i heard these types of motors are very well suited for this type of work as the torque is constant in all speeds
in case your curious or if it will help the motor is
P.M.D.C Motor
model c3364b4035 M
P/N M-314571
2.80HP TREADMILL DUTY @ 130VDC
2.60HP CONT. DUTY @ 110V/1940WATTS
OPEN CONST EXTERNAL FAN.)
i think its a great motor and iv seen lots of lathe build projects by others basically doing the same thing
.but..im having a heck of a time finding a ac to dc speed control in the following config for a perm mag motor
ac input 110v to 220v (regular wall plug juice)
output 110v-130v @ 1940watts...( though i only want a variable speed controller with a 1000-1500 watt max..a online voltage,wattage calc said @ 110v dc at 1000w ill be pulling 9 amps.give or take,@ 1500w =13.6 amps give or take.
i dont think anything more than 1000w-1500w would be needed,for the following reasons
1. at full load of 110v dc @ 1940 watts ill be pulling 17.5 amps
(again according to online voltage,wattage,,calculator found here Volts/Amps/Watts Converter)...
2..i dont need the full 5700rpm that the motor is rated at ..whats a good lathe speed 850 to 1000 rpm max?...
3.i dont need all the heat all this power would produce. (that would just end up killing all the components and be money down the drain..dont you agree?)
so my questions are these
does anyone know of a place that offers plans on building your own ac to dc motor speed control,or a reputable seller of such that doesnt want both my kidneys in exchange for one?
(i hate going ebay cause they have nothing but Chinese sellers selling this kinda stuff..though they are cheap, they take for ever and day for your item to get to you..plus no clue about quality of item..dont want it blowing up in the 3 hours cause of crap workmanship know what i mean Vern?)
is it bad to "under power" or under current a perm mag motor such as this by giving it only 5 to 13 amps when its saying it needs 18?
could under currenting damage the engine?
will i not have enough torque to do a proper latheing work?
must i use PWM on this motor? (heard that PWM is used on brushless motors only)
well thats about all i can think of...please feel free to give thoughts,suggestions and such..any and all information is greatly appreciated.
thanks very much
