How high voltage motors work

Generation of magnetic fields
The first thing that is talked about is the generation of the magnetic field. In a high voltage motor, the magnetic field generated by current flowing through the windings interacts with the magnetic field generated by the permanent magnets or the applied current to form a torque that drives the motor to rotate. The essence of this interaction is the mutual attraction or repulsion between the magnetic field lines of force.

Relationship between magnetic field and current
The current in a motor is subjected to a force in the presence of a magnetic field, causing the conductor to move. This is based on the principle of the Lorentz force, which states that charges are subjected to forces when they move in a magnetic field. In high voltage motors, by controlling the direction and magnitude of the current, we can effectively control the direction and speed of rotation of the motor.

Structure of the motor
The construction of high voltage motors is critical to the generation and utilization of magnetic fields. They usually consist of components such as windings, magnets and bearings. The windings are the path through which the current passes and are the key component in generating the magnetic field; the magnets provide a constant magnetic field that interacts with the magnetic field generated by the windings; and the bearings ensure smooth rotation of the motor.

Controlling the direction and magnitude of the magnetic field
In high voltage motors, we can control the size and direction of the magnetic field by changing the size and direction of the current, thus realizing the control of the motor. This flexible control makes high-voltage motors adaptable to various working conditions and requirements.
Magnetic field is not only a natural phenomenon, but also a key factor in realizing the operation of motors.
