60 mm BLDC motor 3 phase 70W Black and silver for Automatic door

Product description

A brushless DC electric motor (BLDC motor or BL motor), also known as electronically commutated motor (ECM or EC motor) and synchronous DC motors, are synchronous motors powered by direct current (DC) electricity via an inverter or switching power supply which produces electricity in the form of alternating current (AC) to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor. This control system replaces the commutator (brushes) used in many conventional electric motors.

Specifications of brushless motor

Application of brushless motors:

Brushless motors fulfill many functions originally performed by brushed DC motors, but cost and control complexity prevents brushless motors from replacing brushed motors completely in the lowest-cost areas. Nevertheless, brushless motors have come to dominate many applications, particularly devices such as computer hard drives and CD/DVD players. Small cooling fans in electronic equipment are powered exclusively by brushless motors. They can be found in cordless power tools where the increased efficiency of the motor leads to longer periods of use before the battery needs to be charged. Low speed, low power brushless motors are used in direct-drive turntables for gramophone records.

How does a brushless motor work?

In a brushed DC motor, the rotor spins 180-degrees when an electric current is run to the armature. ... In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. A computer then charges the electromagnets in the stator to rotate the rotor a full 360-degrees.

How do I know if my brushless motor is bad?

You can check continuity across the motor leads, any probs with windings would show up there. If it won't run when iots hooked up, check batt voltage and then checkvoltage at esc motor leads - they should be real close. If the voltage is diff, may be teh esc, if voltage is almost the same, its prob motor.

Are brushless motors waterproof?

There are two types of brushless motors—sensored and sensorless. While there are some sensorless motors labeled as waterproof, it is highly advised that you do no submerge these motors or even subject them to extremely wet conditions unless you are prepared for and know how to perform motor disassembly and maintenance.
