Why called brushless DC pump?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The brushless DC pump was initially named because of the use of a\u00a0brushless DC motor<\/span><\/strong>. So let’s start with the DC motor development.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Pros and Cons of brushed DC Motor<\/h3>\t\t\t\t<\/div>\n\t\t\t\t

The early DC motors were commutated by commutators and brushes, so it was called brushed DC motors as it was known to the public. It has the following pros and cons.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Pros:<\/strong><\/p>

Compared to the AC motor, the DC motor has excellent speed control performance, a wide speed regulation range, large torque, good low-speed performance, stable operation performance, and high efficiency.<\/p>

Cons:<\/span><\/strong><\/p>

However, since conventional DC motors are commutated through brushes and commutator contacts, there are several drawbacks:<\/p>

Sparks, Mechanical Wear, Electromagnetic Interference, Loud noise, Short Working Lifespan…<\/p>

Due to the complex structure, the pump’s reliability is poor, easy to be failure, and frequent maintenance is required. In a complex system, it is an important source of the system’s unreliability, so its application is limited.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Pros of Brushless DC Motor<\/h3>\t\t\t\t<\/div>\n\t\t\t\t

The invention of the brushless DC motor benefited from the development of electronic technology, which used transistor commutation circuits instead of brushes and commutators.<\/p>

The structure of the brushless DC motor is similar to that of the AC permanent magnet synchronous motor, with coil windings on the stator and permanent magnets on the rotor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
