See the small pumps are oxygenating pumps, submersible pumps, self-priming pumps, drainage pumps, etc., look similar appearance, but there are still differences, mainly the construction of the motor, some use brush DC pumps, some use brushless DC pumps, so what are the differences and differences between micro brush and brushless DC pumps?Vacuz give you an introduction!

First look at the types of miniature water pumps:

1, DC brushed water pump;

2, DC brushless magnetic drive isolated water pump;

3, brushless motor type DC water pump.

Micro brush and brushless DC water pump advantages and disadvantages:

1、Miniature brush DC water pump

Disadvantages: Because it is brush, need carbon brush mechanical commutation, as long as the motor rotates, the carbon brush will produce wear, when the pump runs to a certain extent, the wear gap of the carbon brush will become larger and larger, and the noise will increase. If it runs continuously for hundreds of hours, the carbon brushes can’t change direction and need to be replaced again, which is more troublesome.

Advantage: simple structure, low price and cost.

2、Micro brushless DC water pump

Disadvantage: The control structure of micro brushless DC water pump is a bit more complicated.

Advantages: Brushless DC motor has been standardized, there are professional manufacturers mass production, low cost, high efficiency and good waterproof performance.

How to wind the stator of brushless water pump:

Most of the brushless water pump stator slot inward, there are four slots, six slots, often using high-speed multi-station internal winding machine also solve the problem of winding, note that different manufacturers, winding machine structure and performance quality are different, in the choice, be sure to keep a sharp eye to avoid the pit, if there is a winding machine do not understand, you can consult Vacuz!
