3 Phase Brushless Dc Motor Description
3 phase brushless DC motors are ideal for applications that require high efficiency, low maintenance, and long lifespan. They are commonly used in industries such as automotive, aerospace, and robotics.
1、Variable Load Speed Range. Brushed motors require what's called a commutator, which alters the magnetic phase within the motor to keep the armature moving.
2、Outstanding Continuous Torque Range.
In a BLDC motor, rotor magnets generate the rotor's magnetic flux, so BLDC motors achieve higher efficiency. Therefore, BLDC motors may be used in high-end white goods (Elevator industry, Robot industry, Medical equipment, etc.), high-end pumps, fans and in other appliances which require high reliability and efficiency.
The parameters and prices of different types of brushless motors are also different, please consult us for specific information!

Shaft out method
3 phase brushless DC motors are ideal for applications that require high efficiency, low maintenance, and long lifespan.
Although the brushless motor was invented in the mid 19th century, it wasn’t until 1962 that it became commercially viable. What is a brushless motor? Brushless motors are synchronous electric motors that move around electronically.
3.How many phases does a brushless DC motor have?
There are three types of brushless motors: single-phase, two-phase, and three-phase. The number of stator windings is related to the number of phases.
In a 3 Phase Brushless Dc Motor, rotor magnets generate the rotor's magnetic flux, so BLDC motors achieve higher efficiency. Therefore, BLDC motors may be used in high-end white goods (refrigerators, washing machines, dishwashers, etc.), high-end pumps, fans and in other appliances which require high reliability and efficiency.
