What are the advantages of using silicon steel sheet rotor for micro geared motor?

Micro geared motor can drive heavy loads, through the combination of micro DC motor and gear reducer, in the structure of micro geared motor core rotor is mostly silicon steel sheet stacked, so what are the advantages of micro geared motor rotor using silicon steel sheet? Today to introduce you to

Silicon steel sheet can be divided into hot-rolled silicon steel sheet and cold-rolled silicon steel sheet; hot-rolled silicon steel sheet means non-magnetic, belonging to the silicon iron alloy, while cold-rolled silicon steel sheet is a small amount of silicon added to the iron, the resistivity is better, magnetic aging significantly improved. The general limit of silicon is about 4.5%. Low silicon and low carbon alloys with high magnetic inductivity and other properties are the materials that make up the cold rolled sheet.

In contrast to low carbon steel sheets, silicon steel laminated rotors not only have high magnetic induction strength but also minimize a certain degree of iron loss. The silicon steel laminated rotor improves the weakness of low losses and reduces the size and weight of the micro motor. In general, silicon steel with excellent permeability is used as the core rotor for low power miniature DC motors because it has low excitation current requirements and significantly reduces iron and copper losses.

Higher power miniature geared motors have a smaller proportion of no-load current to full-load current so iron loss accounts for a larger proportion of the total loss, and using high permeability silicon steel is not significant for efficiency improvement, then it is necessary to reduce the unit loss of the core material to help reduce iron loss.
