Blower Performance
WS7040-12-X200 blower can reach maximum 18m3/h airflow at 0 kpa pressure and maximum 5.5kpa static pressure. It has maximum output air power when this blower run at 3kPa resistance if we set 100% PWM. It has maximum efficiency when this blower run at 5.5kPa resistance if we set 100% PWM. Other load point performance refer to below P-Q curve：
DC Brushless Blower Advantage
(1) WS7040-12-X200 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 20,000 hours at 20 degree C environmental temperature.
(2) This blower needs no maintence
(3) This blower drived by a brushless motor controller have many different control functions such as speed regulation,speed pulse output,fast acceleration, brake etc.it can be controlled by intelligent machine and equipment easily
(4) Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.
Applications
This blower can be widely used onto air cushion machine, CPAP machine, SMD soldering rework station.
How to Use the Blower Correctly
FAQ
Q: Are you factory or trading company?
A: We are factory with 4,000 square meters and we have been focus on high pressure BLDC blowers for more than 10 years
Q: Can we connect this centrifugal air blower directly onto power source?
A: This blower fan is with BLDC motor inside and it needs a controller board to run.
Brushless DC electric motor
A brushless DC electric motor (BLDC motor or BL motor), also known as an electronically commutated motor (ECM or EC motor) or synchronous DC motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic closed loop controller to switch DC currents to the motor windings producing magnetic fields which effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the DC current pulses to control the speed and torque of the motor. This control system is an alternative to the mechanical commutator (brushes) used in many conventional electric motors.
The construction of a brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor. They may also use neodymium magnets and be outrunners (the stator is surrounded by the rotor), inrunners (the rotor is surrounded by the stator), or axial (the rotor and stator are flat and parallel).[1]
The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, nearly instantaneous control of speed (rpm) and torque, high efficiency, and low maintenance. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles. In modern washing machines, brushless DC motors have allowed replacement of rubber belts and gearboxes by a direct-drive design.
