The "DA Motor" is a three-phase AC motor that achieves stable operation with battery power when used in combination with a dedicated controller. Since it is controlled by a frequency command method, the rotational speed remains stable even when the battery voltage fluctuates. It is also capable of operations such as slow up, slow down, forward rotation, and reverse rotation. Additionally, during negative load conditions when transitioning from high-speed to low-speed rotation, energy can be stored in the battery through power generation via regenerative braking. 【Features】 - No carbon brushes, so maintenance is not required for long periods. - High torque even at low speeds, allowing for smooth starting. - Space-saving system construction is possible. *It can be manufactured with a wide range of specifications, including compatible battery voltages and capacities. For more details, please refer to the materials available for download in PDF format. Feel free to contact us with any inquiries.

"AC (alternating current) motor driven by DC (direct current) power = DA motor!" This document contains technical information about the three-phase induction motor "DA Motor System - DA Controller," which can operate on a direct current battery power source. Traditionally, using a three-phase AC motor (induction motor) with a DC power source required voltage conversion through devices like DC/DC converters. However, the DA motor developed by our company only requires driving through a dedicated DA controller, resulting in minimal losses from voltage conversion and enabling efficient charging of regenerative energy back into the battery. **Features** - Drives AC motors with battery power - Fully enclosed external fan type and no carbon brushes, requiring no maintenance for long periods - Rotates based on frequency commands, unaffected by voltage fluctuations - Efficiently returns energy generated during regenerative braking when speed decreases back to the battery - Allows for smooth acceleration, deceleration, forward, and reverse operation - Available voltages include 48V, 96V, 120V, and 288V (other voltages can also be produced) - Capacities range from 0.75kW to 55kW, with a wide variety of options *Please first refer to the technical documentation and catalog.*

It is ideal for preventing humidity (mold) in vacation homes, apartments, and condominiums that are not used for long periods, especially in rooms with high airtightness. On sunny days, the ventilation fan of "Tenkai-kun" spins vigorously due to solar power, expelling indoor air outside and allowing dry air to enter the room. (Note: If an intake is needed, it is provided separately.) It does not operate during rainy weather or at night, so humidity does not enter the room. Since it has no battery, it is maintenance-free. There is no need for switch operation, so there is no worry about forgetting to turn off the power or switch. No management is required after installation, allowing you to open the room with peace of mind. Other specifications are the same as "Ryokai-kun." (There are products available with and without temperature sensors.)

In the summer, doesn't the heat get trapped in the attic, making it difficult for the air conditioning to lower the temperature? When you go up to the second floor at night, don't you feel overwhelmed by the stuffy heat? This is due to the heat that accumulates in the attic during the day. The solar-powered attic ventilation fan "Ryokai-kun" extracts the heat trapped in the attic, enhancing the cooling effect of air conditioners and other cooling systems. Since it uses solar panels for power, there are no electricity costs. It automatically ventilates when the attic temperature reaches 27 degrees Celsius, eliminating the need for troublesome switch operations and not interfering with winter heating. With a low voltage of DC12V, there is no risk of electric shock, and installation is easy.
