Assuming we have a 3 phase motor I've always wondered why is it that the rotor spins rather than just being compleltly pulled towards the direction of the phase or the electromagnet? What causes that angular movement?

The phases of a motor, also known as the stator, create a rotating magnetic field that interacts with the permanent magnets on the rotor. This interaction causes the rotor to spin and creates motion in the motor.
The phases of a motor are made up of electromagnets that are powered by electricity. When the electricity flows through the coils of wire, it creates a magnetic field. By alternating the direction of the electricity flow in each phase, a rotating magnetic field is created.
The permanent magnets on the rotor are crucial for the motor to function. They interact with the rotating magnetic field created by the phases and are repelled or attracted, causing the rotor to spin. Without these magnets, the motor would not be able to generate motion.
Yes, the speed of the rotor can be controlled by adjusting the frequency and voltage of the electricity supplied to the phases. This changes the strength and direction of the magnetic field, which in turn affects the speed of the rotor.
The phases of a motor are arranged in a specific pattern to create a balanced magnetic field that ensures smooth and efficient rotation of the rotor. This pattern also allows for precise control of the motor's speed and direction of rotation.
