STK672-210-E
No. 7464-7/10
t1: The time until the winding current reaches its rated current (IOH)
t2: The time in the constant-current control (PWM) region
t3: The time from the point a phase signal is cut until the back EMF current is dissipated.
t1 = (–L/(R + 0.77)) In (1 – ((R + 0.77)/VCC1) × IOH)
t3 = (–L/R) In ((VCC1 + 0.77) / (IOH × R + VCC1 + 0.77))
VCC1: Motor supply voltage (V)
L: Motor inductance (H)
R: Motor winding resistance (
Ω)
IOH: Set motor output current wave height (A)
The constant-current control time t2, and the time T (= t1 + t2 + t3) that the phase signal is on in each excitation mode
are as follows.
2 phase excitation mode: t2 = (2/Clock) – (t1 + t3)
1-2 phase excitation mode: t2 = (3/Clock) – t1
Determine the values for Vsat and Vdf by substitution using the graphs for Vsat vs IOH and Vdf vs IOH for the set
current value for IOH. Then judge whether or not a heat sink is required from the determined average power dissipation
for the STK672-210-E by comparison with the
ΔTc vs. Pd graph.
Note that it is necessary to check the temperature rise in the actual application system case, since the STK672-210-E
substrate temperature Tc changes with the air convection conditions around the STK672-210-E when a heat sink
without fins is used.
