Why does a three-phase motor induction run without capacitors
Three-phase motors naturally create a rotating magnetic field due to the 120-degree phase difference in the three-phase current, directly driving the rotor’s rotation without the need for capacitors to assist starting or maintain torque output, making the structure simpler and the operation more stable. How It Works The working principle of the three-phase motor includes […]
How to control the speed of a 3-phase induction motor
To control the speed of a 3-phase induction motor, you can use methods like VFDs (Variable Frequency Drives) to adjust frequency, which directly controls speed. For example, reducing frequency from 60 Hz to 30 Hz can reduce motor speed by 50%, saving up to 50% in energy for constant load applications, like pumps or fans. […]
