Description

Model 2210B underwater motor adopts electronic switching device to replace the traditional contact commutator and brush 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.
This is a short shaft underwater motor, and we also have a long shaft one.
This motor comes with a propeller with 3 cables (U, V, W cables) and a base. On the base, it has holes for mounting screws. It is mainly used in underwater ROV robots/UAVs as propellers.
The motor has a maximum thrust of 1 kg and can handle seawater up to 200 meters deep.

Design drawing

About underwater motors

This is an underwater motor with propeller and 3 cables (U,V,W cable).
Brushless underwater motor that is designed for underwater UAV/ROV UAV.
Threaded hole at the top of the motor for fixing the propeller.
The motor is completely waterproof and can handle water depths up to 200 meters.
This motor is short shaft. We also have a long shaft version.
This motor can rotate properly using a conventional brushless motor ESC (Electrical Speed Controller).
This motor has a submerged thrust of up to 1.0 KG (10N).
Customers can use ordinary UAV ESC (Electrical speed control) to drive this motor.
We only produce motors, not ESCs.

SW2210B motor Performance curve (11.1V, 550KV)

Underwater motor advantages

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.

Applications

Widely used in precision electronic instruments, automation equipment, ROV Robots Drones, model drones and intelligent robots and other fields.

Output axis

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.
