1, the winding connection Δ or Y connection, and the rated voltage corresponds to.
2, the rated frequency (HZ) of China's industrial frequency is 50HZ.
3, the length of the base S, M, L (S) short, (M) in, (L) long.
4, the number of motor poles indicates 2 pairs of poles motor that is 4 poles motor (such as Y160M -- 4).
5, the shaft center height indicates that the shaft center height of 160mm.
6, the protection level indicates that the motor can protect more than 1mm solids into (such as IP44).
Extended informationStator core
Role: part of the magnetic circuit of the motor, and on which the stator windings are placed.
Construction: stator core is generally 0.35 ~ 0.5 mm thick surface with insulation layer of silicon steel sheet punching, stacking and become, in the inner circle of the core punching a uniform distribution of grooves for embedded stator windings.
Stator core groove type has the following kinds:
Semi-closed mouth type slot: motor efficiency and power factor is higher, but the winding embedded wire and insulation are more difficult. Generally used in small low-voltage motors.
Semi-open type slot: can be embedded in the molded winding, generally used in large, medium-sized low-voltage motors. The so-called molded windings, that is, the windings can be insulated beforehand and then put into the slot.
Open slot: used for embedded molded windings, insulation method is convenient, mainly used in high-voltage motors.
