Number of commutator valve. Commutator valve number is based on the rated voltage, the number of magnetic poles, and a commutator in the inter-chip average voltage does not produce a ring of fire and excessive spark to decide. The separation distance between copper. The size of the separation distance between copper, mainly based on copper insulation requirements to decide between. To MOULD COMM. When it is, the general requirements sheet to withstand 600 VAC voltage between pieces, which high-voltage leakage current not exceeding 500 A. Low-voltage motors, the voltage requirements can be reduced to 250 VAC. a) Impact Strength: The fibrous filler 70 percent of the highest value, if more filler increases but so reduce the strength . b) bending strength: fibrous filler when 50-70% of the maximum, and then again big or small will reduce the bending strength . c) commutator compressive strength: maximum strength The amount of filler 40-60% compression d) water absorption capacity: With a slight increase in the amount of filler increases. |
