Electric Motor Field Weakening at Arthur Salazar blog

Electric Motor Field Weakening. field weakening is a motor control technique that allows the motor to operate at speeds above its rated speed by weakening the magnetic field in the motor’s stator. field weakening is a method for increasing the speed of rotating electrical machines well above the nominal speed. As a result, field weakening is used where high torque is needed at low rotation speeds and lower torque is needed at high rotation speeds. field weakening enables higher motor speeds by reducing the back emf generated by the motor. This is accompanied by a drop in torque as soon as the speed exceeds the nominal value. It produces a wider speed range for a motor — with a constant. so as you weaken the field, the back emf reduces, increasing the motor current and the power dissipated in the. By reducing the magnetic field strength, the back electromotive force (emf) decreases, enabling the motor to rotate at higher speeds. let’s start with why field weakening is useful:
