Blower Performance

WS7040-24-V200 blower can reach maximum 22m3/h airflow at 0 kpa pressure and maximum 6.8kpa 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) WS7040-24-V200 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

This blower can run at CCW direction only.Reverse the impeller running direction can not change the air direction.

Filter onto the inlet to protect the blower from dust and water.

Keep the environmental temperature as low as possible to make the blower lifetime longer.

FAQ

Positioning and actuation systems

Brushless motors are used in industrial positioning and actuation applications. For assembly robots, brushless stepper or servo motors are used to position a part for assembly or a tool for a manufacturing process, such as welding or painting.Brushless motors can also be used to drive linear actuators.

Motors that directly produce linear motion are called linear motors. The advantage of linear motors is that they can produce linear motion without the need of a transmission system, such as ballscrews, leadscrew, rack-and-pinion, cam, gears or belts, that would be necessary for rotary motors. Transmission systems are known to introduce less responsiveness and reduced accuracy. Direct drive, brushless DC linear motors consist of a slotted stator with magnetic teeth and a moving actuator, which has permanent magnets and coil windings. To obtain linear motion, a motor controller excites the coil windings in the actuator causing an interaction of the magnetic fields resulting in linear motion.Tubular linear motors are another form of linear motor design operated in a similar way.
