"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.*

Introducing our company's first built-in (embedded) type of 'DA motor', a three-phase AC motor driven by a DC power supply! We will design and engineer it to fit your machinery, achieving further compactness and lightweight construction. It is suitable for outdoor machinery such as electric carts, elevators, and pumps, and it operates with high efficiency as it does not require brush replacement maintenance. 【Features】 ■ Built-in type that can be integrated into machinery ■ Easy to change operating patterns due to the DA controller system ■ Uses DC power supply (battery) ■ Power supply voltage can be selected according to application (DC 48V to 288V) *For more details, please refer to the materials. Feel free to contact us with any inquiries.

The "DA Motor / DA Controller" is a three-phase induction (AC) motor (with sensor) that can be operated on battery power. By driving through a dedicated DA controller, voltage conversion losses are minimized, allowing regenerative energy to be efficiently charged to the battery. The DA motor is a totally enclosed external fan type and does not have carbon brushes. It requires no maintenance for an extended period, reducing maintenance efforts. 【Features】 ■ Drives an AC motor with battery power ■ Voltage options include 48V, 96V, etc. (other voltages can also be manufactured) ■ Compact size is less than 1/10 of our product volume ratio ■ Totally enclosed external fan type and no carbon brushes, requiring no maintenance for a long time ■ Slow up, slow down, forward, and reverse operation are all possible ■ Due to frequency command, rotation remains stable even with voltage fluctuations *For more details, please refer to the materials. Feel free to contact us with any inquiries.

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.
