Waterproof DC Brushless Motor

Waterproof DC Brushless Motor usually consists of a permanent magnet rotor and a coil wound around the stator. It eliminates the need for brushes in the rotor components by designing the permanent magnets in the rotor. Therefore, compared to a brushed DC motor, this product does not contain any brushes, so it does not generate a small amount of heat for brush wear.

1. Waterproof DC Brushless Motor usually consists of a permanent magnet rotor and a coil wound around the stator. It eliminates the need for brushes in the rotor components by designing the permanent magnets in the rotor. Therefore, compared to a brushed DC motor, this product does not contain any brushes, so it does not generate a small amount of heat for brush wear.

2. The position of Waterproof DC Brushless Motor's axis is fed back to the control circuit, so it is used for closed loop applications. Its potentiometer is connected to the shaft. It allows the control circuit to monitor the position of the motor. The position is compared to a reference input signal by a control circuit. The output of the control circuit is fed back to the motor. If there is any mismatch between the current position and the reference position, an error signal is generated at the output of the error detection amplifier. Based on this signal, the axis rotates and goes to the desired position and stops.

3. Waterproof DC Brushless Motor's wires power the stator coils to drive the permanent magnets mounted in the rotor. The lack of brushes eliminates sources of wear and electrical noise, but it requires more complex external commutation circuits, which requires some way to measure rotor position to produce the correct motor current. Above several thousand revolutions, the rotor position can be measured by observing the zero-crossing voltage induced by the rotor motion in the winding. At lower RPM, it is more reliable to add a Hall effect sensor to directly measure the rotor field.
