Explosion-proof Motor With Water-Cooling System for excavating coal has special character such as small size

high power and terrible heat

etc.Electric-magnetic parameter is optimized which makes distribution of power losses suited according to the figure of heat conduction.Reciprocation watercourse is adapted to cooling system which improve capability of heat-conduction.Temperature of stator winding is calculated on the basis of model of heat conduction.Main mechanical stress of axis and baseframe are calcu...
