Do microwaves need to rotate?

It is possible to cook or heat food in a microwave that doesn’t spin or doesn’t have a turntable. But a rotating turntable helps spread the heat more evenly so that the food is heated sufficiently, which can ensure to kill all microorganisms while preserving all the valuable nutrients. And this is what matters most!

Why the microwave oven disk rotates at slow speed?

Microwaves have ‘hot’ spots, and ‘cold’ spots. That is the reason for the rotation, to account for the uneven distribution of the waves that excite the water molecules to heat the food. If the food sat in one position, there would be areas that would be hot, and other areas that would be totally cold.

Can I use microwave without turntable?

The microwave can be used without the revolving glass tray if the door glass is undamaged. The food won’t cook as evenly without the revolving tray and will need to be manually rotates during heating.

Why does a disc drive have to rotate the right way?

Motors that must rotate the right way (eg disc drive motor) may use sensorless systems that derive back EMF voltages from the motor windings BUT circuitry is included to check rotation and adjust the powering if direction starts wrongly.
