Please refer to the attached PSpice pics...
The load is 10.45 ohms motor, and the voltage and current supply (for stall) sould be around 6V and 0.4A.
That is around 2.5W... right?
so the current around 0.6A flows through the NPN transistors...
The problem is that the heat sinks of both NPN Transistors get too hot (so I cannot touch it). Are they supposed to be that hot?
I don't see why it gets that hot.
Here's the spec for the NPN transistors I have... TIP 29C and TIP 41C
TIP 29C
Ic (DC) 1A
Pc, Collector Dissipation (at Tc = 25 C) 30W
Pc, Collector Dissipation (at Ta = 25 C) 2W
Junction Temp 150 C
Storege Temp -65 ~ 150 C
TIP 41C
Ic (DC) 6A
Pc, Collector Dissipation (at Tc = 25 C) 65W
Pc, Collector Dissipation (at Ta = 25 C) 2W
Junction Temp 150 C
Storege Temp -65 ~ 150 C
