This question already has an answer here:
I know it might be a naive question but am not really an electrical or a mechanical engineer, but am in a situation here and I need some help. I work in motorized rolling doors and I need to know how to chose the right motor for the door I have. Basically I want to calculate how much a motor can lift, maybe a general rule of thumb on how does it work.
So the information I have is Torque (Nm), hollow Shaft diameter (mm), voltage (V) output speed (RPM), and motor output (kW).
And as an example of this is that i have an industral motor with
- Torque = 450 Nm,
- Hollow Shaft = 40 mm,
- Voltage = 230/400 V,
- Output Speed = 14 RMP
- Motor output = 1,5 kW
