product details:

Function:

A carbon brush acts as a sliding electrical contact that transmits current between stationary and rotating parts within an electric motor or generator. This ensures a continuous flow of electricity and allows the motor to function.

How They Work:

1. Current Transfer: The motor receives electrical current from the power source (battery or outlet).
2. Stationary vs. Rotating Parts: Inside the motor, the commutator (in DC motors) or slip ring (in AC motors) is a rotating component. The carbon brushes remain fixed in position.
3. Making Contact: The brushes press lightly against the surface of the commutator or slip ring, creating a point of electrical contact.
4. Current Flow: The electrical current from the stationary source flows through the brushes and into the rotating commutator/slip ring, ultimately powering the motor’s electromagnetism and causing rotation.

Features:

• Material: Typically made from a specially formulated graphite mixture that offers good electrical conductivity and low friction.
• Shape: Can vary depending on the application, but common shapes include rectangular blocks and round rods.
• Spring Contacts: Springs are often used to maintain consistent pressure between the brushes and the commutator/slip ring for optimal current transfer.

Benefits of Carbon Brushes:

• Low Cost: Compared to other contact methods, carbon brushes are a relatively inexpensive solution.
• Self-Lubricating: The graphite in the brushes provides some inherent lubrication, reducing friction and wear.
• Current Smoothing
