Description
ReGen (Energy saving control system)
Adopting the high-quality IPM, built-in high speed DSP chip on the main board can regenerate the high-quality of the electric power. Basically it returns regenerated energy from motor into the buildings internal power network for re-use.
Not only realization of the function for energy regeneration but also, improvement of noise, vibration and ride comfort enhancement.
Features
- Saving energy, the protection of the environment matching with PMSM and saving 58% energy.
- Eco-friendly technology
- Suitable for gearless motor that consumes 50% less power
- Adopted the newest IPM and main board
- 100% energy regeneration under motoring condition as well as regeneration condition
- Adopted high efficient EMI noise filter, more clean feedback energy
How it works
| The condition 1 of the energy regeneration : The car moves up with the car lighter | The condition 2 of the energy regeneration : The car moves up with the car lighter |
|
|
The car moves up with the car lighter In case the car is lighter than the balance weight, the motor works under generation mode. Also the eletric energy is generated and regenerated to a distribution panel by ReGen unit. | The car moves up with the car heavler In case the car is heavier than the balance weight, the motor works under generation mode. Also the eletric energy is generated and regenerated to a distribution panel by ReGen unit |
Standard Specifications
- Uniform energy saving effect It may differ depending on speed/weight/floor, and max 70 % effective in energy saving compare to Non-ReGen system.
- Outstanding energy regenerating quality Precise controlling and high performance filter make clean regenerating energy to power supply.
- Keeping the power factor always to be 1 or -1 The phases of current and voltage waveform are exactly same (Same during motoring, 180 degrees phase difference) whereby the power factor is always kept 1 or -1.
- A decrease in harmonic distortion Current waveform has no distortion and almost sine wave, so harmonic distortion from external device drastically decreases.
- Improvement in ride comfort Maintain constant DC bus voltage during motoring and regenerating for better ride comfort.
- Favorable for power voltage fluctuation Even power supply’s voltage is fluctuated, constant DC bus voltage is kept.
- Reducing the size of the elevator controller In the existing braking resistor method, the more inverter capacity is required, the larger braking resistor room is also required.
- Keeping down the machine room temperature Because machine room temperature is kept down without using braking resistor, cooling facilities diminish and the parts last a long time.
- Sustainable technology Realization of environmentally friendly technology with prevention of global warming and recycling energy
