L'ESC est spécialement développé pour la propulsion sous-marine avec les caractéristiques suivantes.

1) Le micrologiciel propriétaire des propulseurs ApisQueen est spécialement conçu pour améliorer les performances supérieures des propulseurs. Le PWM du moteur généré par le matériel améliore la réponse de l'accélérateur et réduit le bruit.

2) Le micrologiciel propriétaire d'ApisQueen génère un freinage régénératif pour le rendre plus efficace. Lorsque la manette des gaz passe de grande à petite, les propulseurs décélèrent et répondent plus rapidement, ce qui améliore grandement la stabilité et la flexibilité des propulseurs.

3) L'ESC détecte automatiquement le signal d'accélérateur à la mise sous tension et prend en charge une entrée de largeur d'impulsion de 1 à 2 ms, une seule prise et plusieurs prises en mode d'accélérateur PWM normal.

4. supporte Dshot150, Dshot300 et Dshot600. Dshot est un signal numérique avec une forte capacité anti-interférence, l'ESC n'a pas besoin de calibrer la course de l'accélérateur.

5) Le câble de signal adopte une paire torsadée de fils de silicone, ce qui augmente sa durée de vie et réduit efficacement les interférences causées par la transmission du signal dans les fils de cuivre, ce qui rend le propulseur plus stable.

Pour la modulation de largeur d'impulsion

Le nom complet de PWM est (Pulse-width modulation). La période complète de la MLI est de 2 ms, l'arrêt de 1,5 ms, la marche avant de 1,5 à 2 ms et la marche arrière de 1,5 à 1 ms.

La figure montre clairement que lorsque le PWM est de 75 % (1,5 ms), le moteur s'arrête de tourner, lorsque le PWM est de 50 % (1 ms), le moteur tourne en sens inverse, et lorsque le PWM est de 100 % (2 ms), le moteur tourne en sens inverse. Bien entendu, l'ESC ne permet pas seulement au moteur de tourner en avant et en arrière, mais il régule également la vitesse de rotation du moteur par la taille du rapport cyclique du PWM. Lorsque le PWM passe progressivement de 75 % à 50 %, le moteur continue à commuter et à accélérer à partir de l'arrêt jusqu'à ce que la rotation inverse atteigne la valeur maximale. Lorsque le MLI passe progressivement de 75 % à 100 %, le moteur continue d'accélérer de l'arrêt à la rotation avant jusqu'à ce que la rotation avant atteigne la valeur maximale. En d'autres termes, le MLI est un signal qui peut être modifié en continu avec une plage effective de 50 % à 100 %.

La fréquence du signal PWM est de 50 Hz, 100 Hz, 200 Hz ou 500 Hz. Plus la fréquence de contrôle est élevée, plus la période est courte, plus l'intervalle de contrôle est court, plus la vitesse de réponse de l'ESC et du moteur est rapide, plus la vitesse de réponse de l'ESC et du moteur est rapide. Inversement, plus la fréquence de commande est basse, plus la période est longue, plus l'intervalle de commande est long, plus la réponse de l'ESC et du moteur est lente.

ABOUT CUSTOMIZATION

Customization services include: customization of all aspects of thrusters, motors, and ESC;
If you have any customization needs, please contact APISQUEEN (nina@underwaterthruster.com).

ABOUT TARIFFS

The product price and shipping cost do not include tariffs. Tariffs are charged differently in each country, and buyers need to pay tariffs when receiving the goods (for example, the tariff policy in the United States: tariffs are exempted within 800 US dollars).

International imports from certain countries/regions may require specific materials for customs clearance (if necessary, we will provide customers with pro forma invoices).
If the goods are returned due to the customer's failure to cooperate with customs clearance, the freight shall be borne by the recipient.
We can provide consumption lists and certificates. Please contact us when customs requires.
If the buyer causes the return, the buyer shall bear the freight, and the cost shall be based on the selected courier. If the goods are damaged or wrong due to our fault, APISQUEEN shall bear all costs.
The value of the products we declare to the customs is 10% of the actual order amount paid by the buyer, so the buyer generally pays very little tariffs.

ABOUT SHIPPING

We can send goods to almost any country in the world! But you need to pay attention to the import restrictions of some countries.

In the case of stock: the goods will be shipped within 1-3 working days after the buyer pays.
In the case of no stock: the goods will be shipped within 3-20 working days after the buyer pays.

Or there are other problems that delay the shipment, such as the address information needs to be further verified, but please rest assured that we will follow up in time to deal with it so that the goods can be shipped faster.
Goods are generally transported by air. According to the buyer's location, we use different transportation methods. Generally, we use DHL, FedEx, UPS, dedicated lines, etc.
The time for standard express delivery to the destination is generally 3-12 days (without other special circumstances), and the transportation time for remote countries/regions is generally 10-20 days. If you have other needs (such as designated express, customs value declaration, etc.), please contact us after placing an order to ensure that we can meet your requirements.
APISQUEEN sets transportation rates according to different countries/regions. In order to reduce the buyer's purchase cost, APISQUEEN takes the initiative to bear 50% of the shipping costs for the buyer.
Shipping costs are charged according to the weight of the goods and are settled when placing an order. The shipping cost shown in the settlement is the result after APISQUEEN bears 50%.
You can estimate the shipping cost as follows: select the item you want to purchase → add to the shopping cart → enter the zip code of the delivery address → select the delivery method → then you will receive the estimated shipping cost.
If you need the product urgently, please contact us before placing an order to ensure that we can meet your time requirements.

ABOUT AFTER-SALES

The order can be cancelled before the product is shipped to obtain a full refund (including shipping costs). After the goods are shipped, if the buyer requests a refund for his own reasons (for example: he does not want it anymore, bought the wrong one, etc.), the buyer needs to bear the cost of the express delivery and return the goods to us. After we receive the returned goods, we will refund the buyer.
If you find that your package is damaged during transportation, please contact us within 5 days of receiving the goods (nina@underwaterthruster.com), and provide photos or videos of the goods. We will handle it for you according to the actual situation within 1-3 working days to satisfy you.
If you need to replace your purchased goods after receiving the goods, you need to mail the goods to APISQUEEN;Within 6 months after purchasing the product and confirming receipt, if there is any quality problem with the product, we will provide free after-sales service and mail new accessories or new products to the buyer free of charge (the buyer only needs to bear the express transportation fee, APISQUEEN will no longer help the buyer to bear 50% of the freight, and the buyer needs to bear 100% of the freight)
APISQUEEN REFUSES AFTER-SALES SERVICE IN THE FOLLOWING SITUATIONS:
Failures and damages caused by non-product quality problems.
Damage caused by circuit changes or improper matching.
Damage caused by unauthorized modification or disassembly.
Damage caused by improper installation or use.
Failure to clean with fresh water in time after use in seawater, resulting in shortened life.
ALL PRODUCTS ARE "NON-QUALITY PROBLEMS WILL NOT BE RETURNED OR EXCHANGED". PURCHASING OUR PRODUCTS MEANS THAT YOU AGREE TO THIS POLICY.
