2 結(jié)構(gòu)簡介
2.1 定子
定子鐵心采用經(jīng)氧化處理的優(yōu)質(zhì)電工硅鋼片，電磁線及絕緣采用聚酯亞胺漆
包線及優(yōu)質(zhì)復合絕緣等。有繞組的定子鐵芯經(jīng)真空高壓浸漬，使之成為一個完整
的整體，并按照 JBZ294 和 GB2423.4 進行試驗，具有優(yōu)良的電氣，機械，防潮
及熱穩(wěn)定性。
電動機的絕緣等級為F 級，溫升裕度大，壽命長。
2.2 轉(zhuǎn)子
轉(zhuǎn)子鐵芯也采用經(jīng)氧化處理的優(yōu)質(zhì)電工硅鋼片制成，經(jīng)鑄鋁后用熱套法固定
有轉(zhuǎn)軸上，并經(jīng)動平衡校驗，電動機運行平穩(wěn)，振動小。軸采用45＃鋼制成，電動機只有一個軸伸，如用戶需要時，可提供雙軸伸電
動機。
2.3 接線盒
接線盒位于機座正上方，（H80—180及H355）或位于機座右方（H200—315）
（從軸伸端視之），用戶有特殊要求時，可在訂貨時說明。接線盒內(nèi)設(shè)有接線板
或安裝板，接線板上有六個接線端子，適用于電動機直接起動或 Y-△起動，接
線盒內(nèi)設(shè)有接地螺栓，確保安全，接線盒內(nèi)側(cè)設(shè)有接線圖，供接線時參考。
2.4 軸承及軸承室
產(chǎn)品設(shè)計時選用低噪聲電機專用軸承，機座號 H80—132 采用雙面密封球軸
承，軸伸端軸承室內(nèi)裝有波形彈簧片，以適度的彈力壓靠軸承，H160—355電動
機軸承結(jié)構(gòu)為內(nèi)、外蓋式，且非軸伸端用擋圈定位，有效地防止了電動機轉(zhuǎn)子的
軸向串動，機座號315—355具有不停機注、排沒裝置，以確保軸承良好的潤滑。
2.5 風扇，端罩
全系列風扇與軸采用鍵配合，運轉(zhuǎn)可靠。
端罩為薄鋼板結(jié)構(gòu)，在防止一定大小的外物侵入的前提下得到最大的通風面
積，從而使風路順暢，外形美觀。鋼性好，防護等級為IP20。
2 Construction
2.1 Stators
The stator cores are laminated from the oxygenated high-quality magnetic sheet
steel. The magnetic wire adopts polyamide enamel wire and the insulation the
premium discontinuous insulation. The completely wound stator cores are
vacuum-pressure impreg-nated to a solid integral. Then they are tested according to
JB/Z294 and GB2423.4. This process enables the windings to possess excellent
electrical and mechanical properties, high moisture-resistant ability and thermal
stability.
The insulation is Class F, but the temperature rise limit is specified as that of
Class B. Thus makes the motors be of a large margin of safety in temperature-rise and
long service life.
2.2 Rotors
From the oxygenated high-quality magnetic sheet steel are laminated the rotor
cores which are cast aluminum and fixed on the shaft by means of hot fit. They are
well calibrated wity dynamic balance to make motors operate smoothly with little
vibration.
The shafts are made of 45# steel. The motors are manufactured with only one
shaft extension end. If customers require the motors with double shaft extension ends,
please specify them when ordering.
2.3 Terminal Boxes
The terminal boxes are on the just right top of the motors (frame size H80~180
andH355) or on the right side of motors (frame size H200~315)seeing from the
driving end. Special requirements should be stated when ordering. Aterminal board or
fixing board is equipped in the terminal boxes. There are six terminals in the terminal
boxes, suitable for motors direct-on-line starting or Y-△ starting. Anearthing
bolt is equipped in each terminal box to ensure safety. There is a
connection diagram inside the terminal boxes for reference.2.4 Bearings and Bearing Chambers
The motors are fitted with low noise bearings special for motors. For
frame size H80~312 motors, bilaterally shielded ball bearings are adopted and a
corrugated spring washer within the bearing chambers at the driving end which is
pressed on the bearings with suitable elasticity. But for frame size H160~355 motors,
the bearings with inner and outer covers are used and a retaining ring is fitted at the
non-driving end to prevent efficiently rotors moving axially. For frame size
H315~355 motors, on each bearing bracket there is a greasing attachment having the
use to drain and replenish the lubricating grease without stopping the motors to ensure
the bearings in good lubricating condition.
2.5 Fans and Cowls
The fans of whole series motors are keyed on to the shafts to ensure reliable
operation.
The cowls are made of fabricated steel. On a prerequisite that it should prevent
from the ingress of solid substances of certain size, they enable the motors to get
maximum area of ventilation in order to form adequate air current. The cowls are of
fine looking and good steel strength. The degree of protection is IP20.
