Does microwave need to rotate?

The turntable is there to make the heating a bit more even but it has absolutely no impact on food safety. … If the turntable didn’t spin, the food won’t be cooked evenly, and will have hot spots and cold spots.

Why does a microwave spin both ways?

Rather, the reversal has to do with the relatively inexpensive turntable motors designed for use in most microwaves, said Robert J. … By design, they reverse their direction of rotation if a load greater than their output torque, or twisting force, is present, he said.

Is a microwave turntable necessary?

Not necessary, but useful. The nature of a microwave oven is that it will have “hot spots”, not because of the oven itself, but because of the shape and size of the food that’s in it (so it varies). The turntable keeps you from having to fidle with the food to some extent.

What way do microwaves spin?

The turntable can turn in either direction when the microwave starts cooking. For example, the tray might rotate clockwise one time and counter-clockwise the next, or turn clockwise twice in a row. Electrical circuitry causes this direction change, and is normal.

What is the wavelength of a microwave?

Microwaves have frequencies ranging from about 1 billion cycles per second, or 1 gigahertz (GHz), up to about 300 gigahertz and wavelengths of about 30 centimeters (12 inches) to 1 millimeter (0.04 inches), according to the Encyclopedia Britannica.

How do microwaves without turntables work?

MIcrowaves with turntable and microwaves without turntable both have the rotating motor inside the appliance. The rotating motor of a microwave with turntable drives the glass plate, while the rotating motor of a microwave without turntable drives the stirring blades hidden under the flatbed.

How do you test a microwave turntable motor?
