motor torque
(OP)
frequency 10 Hz
Amplitude 0.0005 meters
max acceleration 1.97392088 m/s/s =Amplitude X power(2 X PI() X f, 2)
Mass 1 Kg
Force acceleration 1.97392088 nt f=ma
Torque @ 0.5mm 9.86960E-04 nt m Torque = Force X Distance
in Kgf cm 0.010071025 Kgf cm
Is this calculation correct, actually I wan to decide a stepper motor for my application

T=Nt.m
N=Rpm/min(rotation speed) according to frequency.

1 meter = 100 centimeters
RE: motor torque
The conversions are correct.
9.8698x10^(-4) N-m = 9.8698x10^(-4)/9.8 Kgf-m
= 1.007102x10^(-4)Kgf-m
= 0.01007102 Kgf-cm
Since it was too low so I thought must have made some calculation error.
Thanks

Torque @ 0.5mm 9.86960E-04 nt m Torque = Force X Distance
///Torque @ 0.5mm = Force x Distance = 1.97392088 nt x 0.0005 m = 0.00098696 nt-m.
Your calculation is about correct.

RE: motor torque
Torque = inertia x rotational acceleration
Using force x radius will give you a static torque if the load is vertical (being raised or lowered) or has an acting force applied to it. Instead of me going into all the details, there are many sizing software packages out there that can help you and many Engineering references that can help you. Most Motion Control Mfgs. will have formaulas in their catalogs. Even mine does, check out: http://www.aerotech.com/psd_cat/psdtoc.html
I can give names/links of others if interested.
