brushless motor gearbox

[Iena]

Hello everyone.. .
I have a problem... I have to couple a brushless motor to a reducer, but I can't find anything outside of those epicloidal ones (which I want to avoid).....consigli?

 

[gerod]

take a brushless with pam flange or make you a coupling flange.
I've done it before.

the choice of the reducer depends a lot on the application! !

see that epicloid reducers have several advantages:
high reduction ratios;
high couples to transmit;
high loads to so0pport on the outgoing shaft.

the alternative can be parallel gear reducers.

alpha produces a v.s.f. series that has more or less the same performance as epicloidal, to hear them: the v-drive series.

also washed costs...



cmq thanks to all... excellent tips

you should specify some things, like:
- What do you have to do?
- Why do you use a brushless?
- Why do you hate epicloids so much?

There are many solutions, there are harmonic drives, cyclo drives, torque motors.. .

mha, I have used several times epicicloporcoidali gearboxes with brushless motors (bruseless, in friulano) and I have never had problems.. .
I would like to understand why of distrust.. .

It seems to me that the only distrust is purely economic.
Of course brushless/epicycloidal is his death and hyena knows it well:biggrin:.
depends on the use you have to make.
seems absurd to spend a package for the drive motor/management and want to save on the reducer, but it happens.. to me they have just now made me mount a brush with a "normal" vsf motorvary from a few lires.. sicché:biggrin:
AimWhat size are we talking about?

You're perfectly right, and it's the same objection I made to those who commissioned my job. the problem that becomes more problematic to change the electronics..mi spego, the electronic application is already tested, unfortunately are born of the different needs that led us to the conclusion that changing the electronics needed time of programming and supplying material longer... I hope to have been clear

I understand. .
However the coupling can be dared.
This is the acrocchio that happened to me to assemble:greetings

in fact... very similar to what I just heralized. .. between engine and gearbox I broke a torsionally rigid joint

You should check that the v.s.f. game (which is usually larger than that of an epicloidal) is compatible with your application.

If you have to do positionings, you may find yourself with bad surprises at the control level, with the engine that keeps going back and forth from the waiting position because it can't find the stop point because of the transmission games.

I would like to refer to this old debate for a similar question. I should couple a brushless motor to an angle reducer to move a trapezoidal screw.
I read that a solution use a flange to mate an endless screw reducer with a brushless pam flange.
but the reason for this thread is that the epicloidal reducer has higher prices? How much in percentage?
In any case, I should choose a reducer and couple it to a brushless motor. do you suggest some catalog for angle gearboxes for incoming pairs around 250 nm and reduction ratio between 1:15 and 1:30?

 

[brn]

What do you need to do?
Do you have a dynamic so pushed to require a brushless?
250 nm with reducer 30 makes a nice servo-reducer, then if you have to put a trapeze screw comes a push that are not bruscolini. . .
I'd like to see if you need a servo-reducer or an industrial epicloidal. . .

 

[PiE81]

@brn a clamping clamp, I talked about it qui. I am evaluating the most suitable solution (and economic).
However it is an axial load of 50kn to transmit to a trapezoidal life. the load is not dynamic but during the locking then at speed nothing.

I would say that you don't need a brushless motor.
you just need a no three-phase asynchronous motor to power with inverter and retroaction with encoder in order to give maximum torque at zero speed.
the endless screw reducers of medium/small size cost little, especially bonfiglioli that sells a lot. if you go on an epicloidal you pay it a 30/40% extra. then a vsf is tendentially more irreversible than an epicycloidal which is not evidently (although with i=30 is not irreversible).

for the adaptation of brushless motors on pam are usually made of aluminum flanges with holes and centrings specifically to mount them without buying the frame flanged reducer....that maybe there is.

Yes, 90% will opt for a three-phase asynchronous. I was putting on the table the various possibilities and costs, pro and con.
the brushless solution comes easily between 2000 and 3000€ (between engine, drive, reducer). I think instead, opting for the asynchronous to feed with retroaction with encoder, the prices are lower.

 

[meccanicamg]

we try to do with the configurator of red gear... We choose endless lives and look for something that has 250nm•30=7500nm out at 1400rpm.

observation: 250nm at 1400rpm in the entrance are 37kw.... are you sure of this?
we have no gearbox to choose.. . .

before you go crazy. . .quire perera choice of the reducer have the clear data.....reduction ratio, motor 4poli, torque output reducer etc.
Report 15 or 30 is not good... one... .
