Determining Chopping Frequency
The STK6713BMK4 uses constant current for self-excitation.
The IOH tOFF time is set to about 14 µs, and the tON time can be expressed as:
L
VCC – ( IOH e
VCC + 0.88
(1 – e
)) (R + 0.88)
tON
R + 0.88
In (
R
) ............................ (5)
VCC – (R + 0.88) IOH
L:
Motor winding inductance
R:
Motor resistance
VCC: Motor supply voltage
IOH: Output current
As a result, the chopping frequency is
F
=
(Hz) ................................................................................................ (6)
However, note that when the following conditions exist the value for F will change.
14
× 10–6
In (
) = tOFF2 ............................................................................. (7)
tOFF ≈ tOFF1 + tOFF2 = 14 × 10-6 + tOFF
∴F =
(Hz)........................................................................................................ (8)
Because the STK6712BMK4 is self-exciting there will be minor variation in motor inductance during motor revolution.
Final design verification is required in an actual model.
Thermal Radiation Design
The HIC radiator plate size is dependent on the motor output current IOH (A), motor electrical characteristics, excitation
mode, and excitation input signal clock frequency fclock (Hz).
The thermal resistance for the radiator can be determined from the following expression.
θc – a =
(°C/W).................................................................................................................. (9)
Tc max = HIC substrate temperature
(°C)
Ta = set internal temperature
(°C)
Pd = HIC internal mean power dissipation (W)
