The 2210A underwater motor adopts electronic switching device to replace the traditional contact commutator and brushes for electronic commutation. Therefore, it has the advantages of high efficiency, high reliability, no commutation sparks and no interference, low mechanical noise and high lifetime. The motor has a maximum thrust of 1 kg and can handle seawater up to 100 meters deep. It has a propeller, three wires and a base. On the base, it has holes for mounting screws. Main application underwater ROV robot/UAV as propeller.Widely used in precision electronic instruments, automation equipment, ROV Robots Drones, model drones and intelligent robots and other fields.1.Wiring method First of all, the motor, power supply and ESC should be selected accurately according to the load and use conditions, the power supply voltage is too high is likely to cause damage to the motor and ESC, the power supply discharge power is insufficient to allow the motor to reach the rated power and affect the use of the effect. ESC selection should also be matched with the rated voltage of the motor. Motor installation screws should not be too long, so as not to damage the motor coil. Before wiring, for safety, please remove the motor load, first connect the ESC and motor three leads (three leads can be switched two to change the direction of the motor), and then connect the ESC signal line, pay attention to the signal line wiring order, do not connect the reverse. Finally connect the DC power supply, positive and negative polarity can not be reversed, most of the market ESCs have reverse protection, no reverse protection ESCs in the power supply positive and negative polarity will have the risk of burning. 2.Throttle travel calibration. When using ESC for the first time, or change the PWM signal source, or use the throttle signal out of calibration for a long time, you need to calibrate the throttle travel.1. Waterproof and moisture-proof to avoid short circuit of electrical components inside the chamber. 2. Effective blocking of dust and particles to avoid bearing wear. 3. Keep the cavity dry to avoid the motor and motor being corroded and oxidized, resulting in poor contact or leakage.Lead time for samples: Standard motors in stock: within 3 days Standard motors not in stock: within 15 days Customized products: About 25~30 days (based on complexity of customization) Lead time for building a new mold: generally about 45 days Lead time for mass production: based on order quantity Packaging: Samples are packed in foam sponge with a paper box, shipped by express Mass production, motors are packed in corrugated cartons with transparent film outside. (shipping by air) If shipped by sea, product will be packed on palletsOn samples and air shipping , we use Fedex/TNT/UPS/DHL. (5~12 days for express service) For sea shipping, we use our shipping agent, and ship from Shanghai port. (45~70 days for sea shipping)

 Because brushless motor uses electronic commutation, so let brushless motor operation need to adapt to the motor voltage DC power supply, driver (ESC) and speed control signal. Take a common model ESC as an example, first disconnect the power supply, connect the motor leads and speed signal line, the throttle travel to the highest (full duty cycle), connected to the power supply, you will hear the "drop" two sounds, the throttle travel quickly to the lowest position, and then you can hear the normal start of the motor "drop ---- drop" sound, the throttle travel calibration is complete, you can start the motor normally. (The operation mode of ESC may be different for different manufacturers, please refer to the manual of the corresponding ESC model or consult the ESC manufacturer for details) Customers can use regular drone ESC (Electrical speed control) to drive this motor. We only produce motors, and we do not provide ESC.1.Are you a manufacturer? Yes, we are a manufacture, and we produces mainly stepper motors. 2.Where is your factory location?
