步进电机知识详解,再不怕看不懂步进电机了!
Tf = G * r
TJ = J * dw/dt
J = M * (R12+R22) / 2 (Kg * cm)
n = q * Hz / (360 * D)
(1) 通常情况下 TJ = 70%Tm
(2) tr = 1.8 * 10 -5 * J * q * (F1-F0)/(TJ -TL)
(3) F (t) = (F1-F0) * t/tr + F0, 0<t<tr< span=""></t<tr<>
TJ0 = 70%Tm0
TJ1 = 70%Tm1
TL = 60%Tm1
tr = F4 * In [(TJ 0-TL)/(TJ 1-TL)]
F (t) = F2 * [1 – e^(-t/F4)] + F0, 0<t<tr< span=""></t<tr<>
F2 = (TL-TJ 0) * (F1-F0)/TJ 1-TJ 0)
F4 = 1.8 * 10-5 * J * q * F2/(TJ 0-TL)
