Its surface is made of good thermal conductors such as aluminium [Al] or ceramic materials. Some heating plates exclusively use radiation sources such as infrared (infrared light) for heating. Stirring hot plates have a heating element (an electrical resistor), a control system (on and off, temperature control, agitation control and its respective motor). The motors used in these types of instruments are generally of single phase induction named shaded pole1. The speed range depends on the number of poles and the frequency of the feed voltage.en-USStirring Heating PlateBook chapter
