Discuss steps in determining upper and lower temperature des

Discuss steps in determining upper and lower temperature destruct limit and operating limit for 6-inch personal fan with oscillatory motion tor household use involving plastic blades, motor speed control, electric cord, and casing. HASS: Design HASS for the fan mentioned above.

Solution

Ther limit deals with the thermal energy produced by current in

a) the wires

b) the motor due to iductive effects

Need to know the plastic properties, so that the temperature range can be estimated for operation. Upper range needed, since lower range will not be reache dunder normal temp conds.

Circuit details impt and whether any cut off components like fuses, thermal resistors and cutouts are included.

lenght of wires and the amperage needed to estimate heat dissipated in the wires.

Do you have details on these,if so can proceed further.
