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.
Converts DC or AC into the required motor input. Control of electric machine drive system
Monitors current, voltage, and rotor position/speed. Maintains a constant ratio between voltage and frequency
Allows motoring and braking in both directions. Control of electric machine drive system
Small fluctuations in torque that cause vibration.
