3-phase Induction Motor (ACIM)
详情介绍
Three-phase induction motors are brushless motors. The stator is copper-wound and the rotor is typically an aluminum squirrel cage. The typical drive configuration is a three-phase bridge (3 half-bridges) modulated to provide three sine wave voltages to the stator. Typically used in higher power applications, the driving portion can be composed of power MOSFETs or IGBTs with high-voltage gate drivers, or power modules integrating three half-bridges and related gate driving stage. Field oriented-control or scalar (volts/hertz) control algorithms are implemented in the microcontroller that controls the inverter.
