Three phase induction motor with conical rotor (YEZ112L-4)
YEZ series three-phase conical rotor brake asynchronous motor, specially designed and manufactured with the construction machinery. YEZ series three-phase conical rotor brake asynchronous motor, fusion motor and brake in one, with a large starting torque, compact structure, can be frequent start and so on.
The working characteristics of YEZ series three-phase asynchronous motor is a conical rotor brake: stator and rotor is conical, in addition to the motor shaft rotate, can axially move when the motor is energized, the stator generates the axial magnetic force of the rotor axial movement and the compression spring, the brake wheel and the brake seat from the rotor to rotate; when when the electrical power, the axial magnetic force disappears, pressure in the spring under the brake wheel and the brake seat friction reduction, fast braking motor.
YEZ series three-phase conical rotor brake asynchronous motor, generally using 50 Hz sesame, 380 volts, B grade insulation, IP4 protection grade.
Note: R is the distance from the mating face to the shaft of the shaft (working hours).
Use and maintenance
1, the motor can be used in the case of no less than 90% of the rated voltage.
2, the first use of a period of time before the no-load operation and a certain number of repeated starting and braking, no exception can be loaded after the use of.
3, the motor can not be explosive, corrosive or other harmful gases in the environment to use.
4, the motor is in use, such as found in the brake ring wear the brake torque is too small, should adjust the relative position of fan wheel brake, the adjustment steps are as follows: first lock screws between the nut and remove the fan wheel brake, tighten the lock nut screw position, finally, if the transfer method is still not. Replace the brake ring. Press the brake, with wooden hammer evenly in the cone ring around the groove, the brake surface angle 20 degrees in lathe cutting after scraping, the back end cover brake contact rate of not less than 80%.
5, bearing grease is generally replaced once every six months, wash after injection of calcium a sodium base grease, if the bearing wear serious, then according to the bearing specifications for replacement.
6, in the handling of motor should be handled with care, storage or use of the motor should be properly packed, good antirust measures, warehouse ventilation drying, re enable the motor before the application of 500V megger insulation resistance, the resistance value of not less than 20M, otherwise it should
