Exhibits

1. New energy automobile pump rotor

This is a utility model structure of the water pump impeller, the external material of the rotor assembly and the impeller under the cover of the secondary plastic coating material are plastic, to avoid different materials caused by thermal expansion coefficient is inconsistent resulting in hot and cold after the gap, greatly reducing the risk of liquid penetration corrosion; In addition, the rotor component in this structure is pre-processed into a component structure, and connected with the lower cover of the impeller and bearing, directly using integral plastic packaging, connection processing, convenient processing, stable connection structure, to ensure the qualified rate of finished products.

2. Motor Hall sensor magnetic plate

This is a kind of magnetic induction sensor, magnetic ring and Hall components composed of induction combination, magnetic ring rotation with the rotor, Hall induction rotation with the rotor of the magnetic ring, magnetic ring usually adopts multiple pairs (even), such as 2 pairs of poles, 3 pairs of poles, 4 pairs of poles, each pole is divided into N, S poles. There are three kinds of Hall element trigger: full pole, double pole and single pole. The existing water flow sensor of water heater uses more single pole latching mode, that is, N pole and S pole output a pulse signal when passing through Hall induction position in turn. In other words, it is a pair of magnetic pole output a pulse signal, and a pair of magnetic pole output multiple pulse signals. Amorphous, nanocrystalline magnetic ring (ultramicrystalline core), the way of opening and cutting the air gap, the addition of Hall chip in the middle, etc.

3. Brushless DC fan motor magnetic ring

This is a multi-pole outer rotor magnetic ring specially used for ceiling fan brush DC motor, with 132 stator, made of injection molded ferrite, filled with 16 poles (5N5S), the specific size is 152.5mm outer diameter, 133.8mm inner diameter, 24-39mm height, magnetic strength around 1650 Gauss.

The blades of the fan need an electric motor to turn them. Compared with brushless motor, brushless DC motor has the advantages of energy saving, large starting torque, small starting current and wide speed range.

4. Magnetic rotor for energy-efficient motor

This is a new type of motor permanent magnet rotor, often used in low energy motor. The permanent magnet rotor enables the motor to save not only materials and space, but also energy, thus making the whole product more environmentally friendly. It is made of stainless steel shaft (with or without through holes), silicon steel core and sintered ferrite by injection molding. The inner hole of this product is 12mm, the outer diameter is 62.8mm, the height is 37.8mm, the outer charge is 8 poles, the power is 120W+, please contact us for more details.
