BLDC motors are a type of synchronous motor. Thismeans the magnetic field generated by the stator andthe magnetic field generated by the rotor rotate at thesame frequency. BLDC motors do not ...

The rotor of a typical BLDC motor is made out of permanent magnets. Depending upon the application requirements, the number of poles in the rotor may vary. Increasing the number of poles does give ...

The four-pole motor, a torque-optimized 22ECT60 (red), quickly loses torque capabilities as speed increases compared to the two-pole 22ECS60 speed-optimized motor (black).

To detect where the rotor is at certain times, BLDC motors employ, along with controllers, rotary encoders or a Hall sensor (see “Brushless DC Motor Control Made Easy”). BLDC motors are ...

Embedded microcontrollers manage dc fans for better cooling while dissipating less energy. The term "dc fan" today normally refers to the type of fan that uses a biphase, brushlessdc (BLDC) motor ...

If you bump the motor hard, or run it hot, too fast, etc. the magnetization will change and your generator changes behavior, usually for the worse. If it’s actually some variant of a BLDC motor ...

Portescap is excited to introduce its latest innovation for the industrial power tools market: the 40EC-Pro PowerTool (PT) ...

[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its rotati… ...
