Thermal Design
An outline of the method for calculated heat dissipation is shown below.
(1)Obtain the value of P
H
that corresponds to the motor coil current I
O
from Fig. 6 "Heat dissipation per phase P
H
vs. Output current I
O
."
(2)The power dissipation P
diss
is obtained using the following formula.
2-phase excitation: P
