1, breakdown phenomenon: Electromotor cannot start, and without any sound. Reason: ① fuse fusing. ② starter drops brake. ③ power source does not have report. 2, breakdown phenomenon: Electromotor cannot start, have buzzing sound. Reason: ① power supply cord breaks a string, or fuse has one photograph fusing, or electromotor has one photograph winding to break a string. The air space between ② stator and rotor is abnormal, make stator and rotor photograph are touched. ③ bearing damages. ④ is driven mechanical check lives. 3, breakdown phenomenon: Fusing of the fuse when electromotor starts. Reason: ① stator coil is received instead. Short circuit of ② stator coil or ground connection. ③ bearing damages. ④ drive leather belt is too close. ⑤ is driven mechanical check lives. When ⑥ starts, operate by accident. 4, breakdown phenomenon: The rotate speed after electromotor starts is inferior. Reason: Voltage of ① power source is too low. ② receives the electromotor of triangular wiring astral form. Short circuit of ③ stator coil. The short circuit annulus of ④ rotor, basket rupture or open solder. ⑤ electromotor passes negative charge. 5, breakdown phenomenon: Electromotor temperature is exorbitant, but electric current did not exceed rating. Reason: ① environment temperature is exorbitant. ② electromotor connects air channel to jam. ③ electromotor greasy filth, dirt is too much the influence comes loose hot. 6, breakdown phenomenon: Electromotor has detonation in move. Reason: ① coil is temporary ground connection. ② coil is temporary short circuit. CNC Milling CNC Machining
