Description
Technical field: the utility model relates to a kind of low voltage high-power threephase asynchronous motor of electric product.
Background technology: at present, domestic low-voltage three phase asynchronous motor when height of center when 400mm is above, generally adopt the steel plate support, unreasonable owing to design, make reason such as difficulty, the motor ubiquity vibration greatly, the shortcoming that noise is high.The motor internal cooling structure is only considered the part, can't cause power of motor on the low side to greatest extent the motor internal heat is guided to the motor outside.In addition, each component structural of motor and flute profile are chosen not science, cause electric efficiency, power factor specification low.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of low voltage high-power threephase asynchronous motor is provided, and it has solved problems such as existing low-voltage three phase asynchronous motor vibration is big, noise is high, power is low.The purpose of this utility model is achieved in that low voltage high-power threephase asynchronous motor is made of: rotor, enclosing cover, bearing 1, bearing 2, bearing holder (housing, cover), end cap, low pressure winding, stator core, support, internal fan, bearing holder (housing, cover), bearing 3, fan guard, external fan, fin, Connection Block, terminal box.Bearing 1, bearing 2, bearing 3 is installed in the bearing holder (housing, cover), bearing 1, bearing 2, bearing 3 is installed in the end cap with bearing holder (housing, cover) jointly, and by the enclosing cover axial restraint, they link together with rotor respectively, end cap links together by bolt and support, the low pressure winding is embedded in the stator core, and be fixed in the support, adopt interference fit, internal fan is connected with rotor by key with external fan, is equipped with fan guard on external fan, and fan guard is fixed by bolts on the support, terminal box is fixed on the support by Connection Block, and base outer is provided with the parallel fin of omnidirectional distribution.This product structure is simple, compact, and is aesthetic in appearance, and noise is low, vibrates for a short time, and power is big, and the high motor power output of identical central exceeds more than two grades than the power output of conventional motors.
