Product Description

Why Choose EC Motor?


EC motors, also known as BLDC Motors, offer the same level of performance but sizes are smaller than other motor. This is because EC fan motors do not rely on carbon brushes, but are controlled by an external electronic circuit board. Therefore, they provide greater controllability and higher efficiency. Therefore, unlike DC or AC motors, brushless EC motors only run when needed and do not overuse energy.


EC Motor Speed Controller


Some interesting questions may come to your mind: how do we know which coils to energize and when to energize the rotor continuously? The answer is, the electronic controller. The sensor determines the position of the rotor, and based on this information, the controller decides which coil to power.

An EC motor consists of an integrated system. It contains:

(a) Converting electronic equipment

(b) Speed control electronics

(c) Stator and DC rotor.



BLDC Fan Motor Structure


BLDC motor is not that complicated, referring to its structure. China brushless bldc motor from CPMDJ consist of a stator and contain a rotating rotor inside, which is surrounded by pole-pieces and a bldc motor controller or called ec motor controller. All our EC fan motors comply with the appropriate International Standards as far as: ec fan motor output, bldc fan motor performance and dimensions of china ec fan motor


CPMDJ's ec motor control has high precision with high performance which is benefit from continuing development of ec motor technology team. Changzhou Changpeng Motor Co.,Ltd is proud to present CPMDJ technology with low temperature rise, silent noise and low vibration. BLDC motor drivers is designed and matached by our own team, economical and high efficiency. 


What is an EC Motor? (What is a BLDC Motor?)


When it comes to motor design, engineers have three main types of choice—alternating current motor (AC motor), direct current motor (DC motor), and electronically commutated motor (EC motor).


What is an EC Motor (Electronically Commutated Motor) ? EC motors are also known as brushless DC motors, ECM motors and BLDC motors. It is direct current, external rotor type of motor in which AC voltage is converted to DC voltage by a commutator. EC stands for Electronic Commuting. EC fan motors are brushless motors whose rotors and onboard electronics are designed with permanent magnets to control the voltage and current applied to the motor. Without getting too technical, it's a brushless motor that uses AC power to run on DC voltage, combining the best of both worlds.


How does a BLDC motor work? The rotor of an BLDC fan motor is a permanent magnet and the stator has a coil arrangement. By applying direct current to the coil, the coil is energized and becomes an electromagnet. The operation of ECM motors is based on the force interaction between permanent magnets and electromagnets. When one coil is energized, the opposite poles of the rotor and stator attract each other. When the rotor is close to one coil, the next coil will be energized. This process is repeated and the rotor continues to rotate.
