Japan Matsushita frequency conversion stepless speed regulation 90W motor with overload limiter protection device


* Streamlined design, internal modular design, suitable for lead-free soldering of SMT and in-line components.

* The spray system uses a centrifugal fan to draw air to prevent the flux from dripping onto the PCB.

* Flux buffer tank sensor external, more reliable and durable.

* Standard cold air knife to prevent flux from spreading outward and reducing pollution.

* Double-wave control uses stepless frequency conversion technology to independently control the peak height.

* 1/4HP high power wave motor with a maximum peak height of 15mm.

* With over-temperature sound and light alarm and emergency braking system, all motors have overload guarantee.

* The transportation system adopts stepless electronic adjustment, closed loop control, and the speed is stable and accurate.

* Pressure auxiliary device at the inlet end to prevent slippage when the PCB enters.

* Forced natural cold air system to meet the cooling slope requirements of lead-free process.

* Manual adjustment of track angle, easy to operate.

* The flux nozzle is driven by a stepper motor to ensure uniform flux coating.

* The spray system is modular in design, and the nozzles are always vertical rails to ensure good flux penetration of the PCB.

* Preheating zone is heated by hot air, high temperature, glass protection and temperature stability.

* Preheating system adopts PID control, the temperature curve is stable, and it is convenient to find the best setting for various lead-free processes.
