Thermal Design
An outline of the method for calculating heat dissipation is shown be-
low.
(1) Obtain the value of P
H
that corresponds to the motor coil current
I
O
from Fig. 7 "Heat dissipation per phase P
H
vs. Output current I
O
."
(2) The power dissipation Pdiss is obtained using the following formula.
2-phase excitation: P

(3) Obtain the temperature rise that corresponds to the calcu-
lated value of Pdiss from Fig. 8 "Temperature rise."
