How do you add a thermistor, a heater and a motor into the circuit?

Depends what type of motor you mean but for some info about modelling DC motors see:

thermistors:

search CL for thermistor

A heater is just a resistor but if you want to model heating a thermistor from the heat from a motor or just from a heater then you need to do some quite complex modelling of how the heat from the heater raises the temperature of the thermistor.

You need to use behavioural sources and and describe the heat to temperature conversions and the temperature to thermistor transfer in one or more expressions.
