torque engine

[SIMONE ALGISI]

good day to all,I need to calculate the power of a brushless motor having the following data:
weight to move vertically 750 kg
pair reducer chosen 450 nm
gear module 3 diam.prim.69
Can anyone recommend me?

If you make a scheme and beds accelerate and give us more information we can help you. However of sti exercises there is full forum as well as looking in google.

post wrong section....what does it have to do with prototyping?

Did you show up?

the essential parameters you did not provide them. lacks speed and acceleration of mass.

As you don't say, I'll make your application.

the law of motion is as follows:from which I reload the acceleration of 125 mm/s2.
imposed formulas for pinion and rack and individual the worst case where I have to climb and I have the weight force added to the force of inertia.If you mount a gearbox with i=144 you can use a 2000rpm-based engine and which drives 0,44kw at the point and zero acceleration, we will have to 0,43kw.therefore you can take a motor with a nominal power 0,43kw and a maximum torque equal to the power of 0,44kw.
with the not very high acceleration you have a difference not very high, otherwise you would see higher maximum powers.

mechanical excusemg, if they are not indiscreet but which program you use, often use these beautiful interfaces

They are excel sheets that I do on various occasions, especially if I study something new and then I repeat with the need.
