Double-cooling surfing pedal electric injection pump power assembly

Abstract

The invention discloses a double-cooling surfing pedal electric injection pump power assembly. The double-cooling surfing pedal electric injection pump power assembly comprises a control mechanism, amotor system mechanism and an injection pump mechanism, the control mechanism and the injection pump mechanism are arranged at the two ends of the motor system mechanism, and the motor system mechanism comprises a motor shell, a motor support, a motor end cover, an encoder end cover, a first rotor bearing, a second rotor bearing, a motor shaft, a stator shaft sleeve, a stator coil, a rotor magnetic rail and an induction magnetic ring. The invention belongs to the technical field of surfboards. The invention relates to a motor rotor, in particular to the double-cooling surfing pedal electric injection pump power assembly which is connected through a double-side bearing, rotates stably, effectively improves the slot fullness rate of a motor, is cooled through internal full-sealed oil circulation cooling and external water cooling, quickly controls the motor temperature, is safe, reliable, free of foreign matter entering the motor, long in service life, low in failure rate and free of pollution.

Description

technical field [0001] The invention belongs to the technical field of surfboards, and specifically refers to a dual-cooled surfboard electric jet pump power assembly. Background technique [0002] Surfing is popular for its thrills and effective physical exercise. Ordinary surfboards can only be used by means of the thrust of wind and waves. When there is no wind and waves or the wind and waves are small, the surfboard will lose its due effect. In order to be able to enjoy surfing even when there is no wind or waves, power surfboards have emerged as the times require. Power surfboards are made of new composite materials. The streamlined hull is beautiful and stylish. The hull is also equipped with control handles and electronic ignition switches. As well as the throttle controller, two-stroke engines and four-stroke engines are installed inside the hull as power sources.

AI Technical Summary

Problems solved by technology

[0003] The power surfboard of the prior art adopts the engine as the power, and can surf on the sea surface and also drive on the calm water surface. Exhaust gas, waste oil and loud noise; the engine failure rate of the existing surfboard is high and the maintenance is cumbersome, the maintenance cost is too high, the corrosion resistance is poor, easy to oxidize, and rust; The load is heavy, causing troubles to users; the electric jet pump in the existing power unit is always a direct cooling structure of propeller pump water spray, the rotor is directly connected on one side, and the noise is large; the existing propeller pump has multiple enameled wires wound together, and the motor The slot full rate is low; the direct cooling structure makes it easy for sand and foreign matter to enter the power unit and the motor, and the service life is short; the motor maintenance rate is high, the failure rate of the electric control system is high, and the maintenance of the motor and the electric control system is difficult
