Hi I am trying to work out how big to make the small pulley that goes on my servo. The smaller I make it the higher the force is on the servo for any given torque.
The Gates manual has recommendations for minimum sprocket sizes on page 8 of their GT3 manual here -
http://www.gatesaustralia.com.au/~/m...nuary-2014.pdf
My servos are:
Nominal power: 750w / 1HP
Normal torque - 2.39Nm
Peak torque - 7.1Nm
Peak power - 2250W / 3HP
The NEMA table in the Gates GT3 pulley design guide lists a 750w motor as having no minimum sprocket size, but if I use the peak power values the minimum recommended size is 2.2"
I cant find anything in my servo manual, they are Chinese KRS servos.
Can anyone help?
