1) Symptom: High motor can not start, lzf vibration anti-blocking devices, but there is no sound. Reasons: ① blown fuse. ② starter out of the gate. ③ Power No power. (2) Symptom: The motor can not start, there is buzzing sound. Reasons: ① a phase power line break, warehouse wall vibrators anti-blocking devices, there is a phase fuse or fuses, or motor with a phase winding disconnected. ② air gap between the stator and the rotor is not normal, the stator and rotor collide. ③ bearing damage. ④ been driven mechanical stuck. (3) Symptom: When Honda brand vibration motor, vibrating screen motor, vibration motor, plate vibrators, vibrating screen manufacturer motor starter fuse is blown. Reasons: ① stator coil an opposite connection. ② stator coil shorted or grounded. ③ bearing damage. ④ belt tight. ⑤ been driven mechanically stuck. Operator error ⑥ start. (4) Symptom: After starting the motor speed is low. Reasons: ① power supply voltage is too low. ② the delta connection motors connected into a star. ③ stator coil shorted. ④ rotor shorting ring, Cage breaks or open welding. ⑤ motor overload. (5) Symptom: Motor temperature is too high, but the current does not exceed the rating. Reasons: ① ambient temperature is too high. ② Motor duct blockage. ③ Motor sludge, dust much of an impact cooling. (6) Symptom: Motor has explosions in operation. Reasons: ① coil temporarily grounded. ② coil temporarily shorted brushless DC motor principle: common DC motor armature to the rotor and the stator to produce stationary magnetic field. In order to make the direct current motor is rotated through the commutator and brushes in changing the direction of current in the armature winding, anti-blocking means, so that the direction of two mutually perpendicular magnetic fields remain, resulting in a constant torque drive motor continues to rotate, Hongda brand vibration motor, vibrating screen motor, vibration motor, flat vibrators, vibrating screen manufacturer, this failure reasons: (1) The supply voltage is too low, if the power line voltage drop is too large, the replacement of coarse power line. If the power supply voltage is too low, be resolved by the electricity sector; (2) the supply voltage is too high, the larger the supply voltage if exceeded, by the electricity sector to solve; and (3) and rotor core motorcycle rub, if the bearing clearance gauge, silo vibration anti-blocking system, replace with new bearings. If the shaft bending, straightening process. If the core is loose, deformation processing core; (4) the winding surface Muddy dirt, foreign material, cleaning or washing motor anti-blocking devices, HTC factory warehouse wall vibrators, explosion-proof anti-blocking devices Xinxiang City Hongda vibration equipment limited liability company provided. Anti-blocking devices, HTC factory warehouse wall vibrators, explosion-proof anti-blocking devices Xinxiang City Hongda vibration equipment limited liability company (www.0373swzd.com) (www.0373hdzj.com) this year introduced a new upgrade, the above picture is for reference, please call Tel picture on this page or to obtain the latest information, contact: Mei Yong.
