BLDC MOTOR TECHNOLOGY

 

It is a brushless motor which uses electronic circuits instead of the  brush used in existing DC motors. It is semi-permanent since it does not use a brush that wears down after each use. The BLDC motor is a cutting edge and environmentally friendly motor with its product life extended by more than 10 times, with decreased noise and vibration levels, and energy efficiency enhanced by more than 20%.

JMW has applied the BLDC motor which is used in high tech machinery such as aircrafts or air conditioners,  in hair dryers for the very first time in the world.

BLDC Technology / Semi-permanent life

Amazing usage time

BLDC Technology proudly presents a semi-permanent motor lifespan with the brushless structure and ball bearing that can be sustained for more than 30,000 hours.

15 times longer lifespan than AC motors, and 30 times longer lifespan compared to DC motors.

BLDC technology proudly provides a semi-permanent motor that can be sustained for more than 30,000 hours.

BLDC Technology / Perfect cold air system

By applying the BLDC motor, it blocks the generated heat, it gives perfect cold wind that no other hair dryer in the world could follow.

By applying the BLDC motor, it blocks the generated heat, it gives perfect cold wind.

Smart heat control system

Unlike normal hair dryers where the motor and the heater operate simultaneously, the JMW hair dryers can respectively control each of them. Therefore, when it is operating on cool air mode only the motor is working, thus blowing out strongly the completely cool water without any residual heat.

BLDC Technology / Excellent energy efficiency

By BLDC motor is low consumption power, high efficiency, competitive advantage available in the market .

Comparison of hair dryers with the same power consuption of 1600W

JMW hair dryer consumes 60W/h.
Can be used with 1540W of power.

Normal DC hair dryer consumes 250W/h. Can be used with 1350W of power.

Comparison of hair dryers with the same power consumption of 1600W

 

Even with the identical power consumption of 1600W, the hair dryer of JMW realizes a much richer amount of heat that is about the same level as hair dryers with the power consumption of 1800W from other companies.

dryers where the motor and heater operate simultaneously, the JMW hair dryers can respectively control each of them. Therefore, when operating on cool air mode only the motor is operated, thus blowing out strongly the completely cool water without any residual heat.

BLDC Technology / High wind speed

BLDC motor - brushless DC motor. JMW has applied the BLDC motor which is used in high tech machinery such as aircrafts or air conditioners.

2X power airflow system

 

 The JMW BLDC motor which spins at a high-speed, intakes two times more air compare to normal hair dryers. The air stream guide inside optimises the wind current providing a richer and a powerful wind.

Powerful wind, at a totally different level, saves more than 60% hair drying time.

The wind speed/air volume and wind pressure of a dryer varies with different types of motors.

The BLDC motor can produce high wind speed/wind pressure with low RPM.

 

 

 

 

The wind speed, air volume and wind pressure of a dryer vary with types of motor-fan and driving environment, and our BLDC motor can produce high speed/wind low RPM.
