What is an electric brake?
An electric brake is a safety feature found in some power tools, including circular saws. It is designed to quickly stop the rotation of the saw blade once the trigger is released, reducing the risk of accidents and injuries.
When the trigger of a circular saw with an electric brake is released, an electrical current is sent to the motor in the opposite direction, causing it to quickly reverse its rotation. This rapid change in direction creates a braking effect that stops the blade from spinning within a few seconds.
The main purpose of an electric brake is to improve user safety by minimizing the time required for the blade to come to a complete stop. Without an electric brake, circular saw blades can continue to spin for several seconds after the trigger is released, posing a significant risk to the operator and others in the vicinity. The electric brake helps to prevent accidental contact with the blade during and after use.
In addition to enhancing safety, electric brakes also provide convenience and efficiency. By stopping the blade quickly, they allow users to make faster and more precise cuts, reducing cutting time and increasing productivity. Electric brakes also help to extend the lifespan of the saw blade by reducing wear and tear caused by unnecessary spinning.
It is important to note that not all circular saws come equipped with an electric brake. When purchasing a circular saw, it is worth considering models that have this feature, especially for those who prioritize safety and efficiency in their work.

How does electric brake work
An electric brake is a safety feature found in some circular saws. It is designed to quickly stop the spinning blade as soon as the user releases the trigger or power button. This feature helps to prevent accidents and injuries by reducing the time it takes for the blade to come to a complete stop.
Principle of operation
The electric brake works by reversing the flow of electricity through the saw’s motor when the trigger or power button is released. Normally, when the saw is in use, the current flows from the power source to the motor, causing the blade to spin. However, when the trigger is released, an electronic switch detects the change and sends a signal to the motor to reverse the flow of electricity.
When the flow of electricity is reversed, it generates a magnetic field in the opposite direction, which creates an opposing force against the rotation of the blade. This opposing force acts as a brake, slowing down and eventually stopping the blade’s rotation.
Advantages of electric brake
The electric brake offers several advantages:
- Safety: The main advantage of an electric brake is improved safety. It significantly reduces the time it takes for the blade to stop spinning, minimizing the risk of accidental contact or injuries.
- Convenience: With an electric brake, users can quickly make repetitive cuts without waiting for the blade to come to a complete stop. This saves time and improves productivity.
- Longevity: The use of an electric brake can also extend the lifespan of the saw’s motor and other components. By stopping the blade’s rotation faster, it reduces wear and tear on the motor, brushes, and bearings.
