H Bridge Motor Control Basics Explained

The video tutorial explains the principles of magnetism, including attraction and repulsion, and how an electromagnetic field is created by current flowing through a coil. It covers reversing polarity by changing current direction and controlling magnetic fields. The tutorial also discusses using magnets and coils for precise rotation, and controlling this with an H bridge and electronic switches. Finally, it explains how the frequency of switching affects control.

What happens when current flows through a coiled wire?

• It creates a static field.

• It generates an electromagnetic field.

• It reduces the wire's resistance.

• It stops the flow of electricity.

How can the polarity of a coil be reversed?

• By increasing the current.

• By using a larger magnet.

• By adding more coils.

• By changing the direction of the current.

What is the role of an H bridge in motor control?

• It controls the direction of current flow.

• It increases the motor speed.

• It reduces the motor's power consumption.

• It stabilizes the motor's temperature.

What is the benefit of using electronic switches in motor control?

• They are cheaper than manual switches.

• They allow for precise timing in switching.

• They consume less power.

• They are easier to install.

How does changing the frequency of switching affect motor control?

• It alters the motor's speed.

• It changes the motor's size.

• It modifies the motor's weight.

• It affects the motor's color.
