torque

First of all, 3.5 Kw power motor for a tbma 320 seems underestimated considering that they could mount a 15 KW motor with 100Nm torque.
you must always keep in consideration 3 motor feature Motor Power Kw – speed Rpm – Torque Nm
P kw = M (Nm) x n(rpm)
9550
M (Nm) = 9550 X P(kw)
n(rpm)
while for manufacturing
Material - type of utensil
(there are various types of tap which can be used with various properties)
necessary torque and speed for the manufacturing,
normally the utensil suppliers are able to give this information
In order to be able To taping M16 you need approximately 40 Nm torque. Obviously this depends on the material, on the RPM used and on the type of type tap used.to be sure they must ask their supplier.
when you have all the information you can increase the torque and decrease speed using some reductions
Reduction between I and H 1.45
available rotating tool in reduction
mra 60 3.052 : 1
mrr 60 2.493 : 1
In order to be able To taping M16 you need approximately 40 Nm torque. Example
MOTOR FANUC ALPHA 3 3.7Kw 23Nm
Using
MRR 60 High reduction
MOTOR TORQUE OUTPUT
23 Nm X 1.45 = 33.35 Nm take power reduction
23 Nm X 3.493 = 57 Nm it could be enough
RPM
1500 : 1.45 = 1034
1034: 2.493 = 425 RPM
MOTOR FANUC ALPHA 3 3.7Kw 23Nm
Using
MRA 60 High reduction
MOTOR TORQUE OUTPUT
23 Nm X 1.45 = 33.35 Nm take power reduction
23 Nm X 3.052 = 70 Nm it could be enough
RPM
1500 : 1.45 = 1034
1034: 3.052 = 338 RPM
obviously considers that to tap, you need 120 RPM final output.
you must verify if the motor in subject has a constant torque under the 1500 rpm , like fanuc alpha 3
if they do the calculations practically could be enough using a High reduction rotating tool
this information is for you, and we do not take the responsibility.
you can advise to do the calculations but the final decision is from the customer.
if they decide to change the engine we can obviously provide flange and pignon.
I hope that this information is useful, I’m at disposal for futher information you may need.。
