Converts DC or AC into the required motor input.
The frequency range where the controller remains effective.
Operates the motor above rated speed by reducing flux. Control of electric machine drive system
Feeds energy back to the source during deceleration.
Controls an AC motor like a separately excited DC motor. Pros: High efficiency; excellent dynamic response. Direct Torque Control (DTC) Converts DC or AC into the required motor input
Allows motoring and braking in both directions.
Runs algorithms (like PID or FOC) on a DSP or FPGA. Control of electric machine drive system
Maintains a constant ratio between voltage and frequency. Pros: Simple to implement; no position sensor needed. Cons: Poor dynamic performance; low torque at low speeds. Vector Control (Field Oriented Control - FOC) Mechanism: Decouples flux and torque-producing currents.
