Next Generation "Three-Phase AC Motor Driven by Direct Current Battery Power" Technical Documentation
Next-generation battery motor! No need for a boost inverter, making it less susceptible to voltage fluctuations, and it provides high torque 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 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.*
