999073 Cepillos de carbón para Hitach DH38YE H45SB2 CR12V

Compatibility Models
Suitable for Hitachi power tools such as DH38YE, H45SB2, and CR12V. Despite varying motor specifications among different models, this carbon brush is engineered and tested to meet the specific current conduction requirements of these tools, ensuring optimal motor performance.

Purpose & Working Principle

• Purpose: As a critical component in power tool motors, carbon brushes conduct electrical current to the rotor, enabling rotational motion. This allows power tools to perform various tasks such as drilling, cutting, and grinding.

• Working Principle: During operation, the carbon brush maintains sliding contact with the commutator, transferring current from the power source to the rotor windings. Over time, the brush will wear down. Replacement is necessary when it reaches a certain threshold to maintain tool efficiency and prevent performance degradation.
