Next Generation "Three-Phase AC Motor Powered by Direct Current Battery" Technical Documentation
Next-generation battery motor! No boost inverter required, less susceptible to voltage fluctuations, and high torque can be obtained from the start!
"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 with a DC 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 according to frequency commands, unaffected by voltage fluctuations - Efficiently returns energy generated during regenerative braking when the rotation speed decreases back to the battery - Free control of slow-up, slow-down, forward, and reverse - Voltage options include 48V, 96V, 120V, and 288V (other voltages can also be produced) - Capacities from 0.75kW to 55kW can be manufactured, with a wide variety available *Please first refer to the technical documentation and catalog.*
