Brief Introduction

HV electric motor, YKK series, has the advantages of high efficiency, energy conservation, high reliability, small vibration, light weight and convenient installation and maintenance.The common structure and installation types of motor are IM B3 and IM V1.

If YKK series of high voltage motor has oil leakage problem or has too much oil consumption, the pressure in bearing chamber may be too high or there is low pressure area outside bearing chamber. Possible reasons are: 1) blocking of air sealing pipe; 2) obstructed oil return; 3) excessive clearance of bearing; 4) sealing problem; 5) loose air sealing pipe; 6) loose air sealing ring; 6) too much clearance between floating sealing ring and shaft; 7) too much clearance between air sealing and shaft.

Thus, the HV electric motor relevant solutions are as follows: 1) clean air sealing pipe; 2) check oil return line and eliminate the cause for obstructed oil return; 3) replace bearing and check concentricity; 4) check sealing pieces; 4) repair air sealing ring; 5) tighten air sealing ring; 6) repair or replace floating sealing ring; 7) replace air sealing ring.
