Carbon brush set for Dedra DED7849 electric motor, replacement parts (MPN YSG047)

Replacement carbon (electrographite) brushes designed for use with Dedra DED7849 electric motors. These carbon brush components restore electrical contact between the rotor and the commutator, enabling correct commutation and stable motor operation. They are intended for maintenance and repair of compatible Dedra power tools and small electric motors, helping to reduce sparking and recover nominal motor performance.

Advantages

These carbon brushes provide a consistent contact surface that supports reliable current transfer and minimizes arcing during operation. Manufactured to match the form and function of the original motor brushes, they simplify in-field replacement and help extend the service life of the motor by reducing wear on the commutator. The electrographite material balances electrical conductivity with mechanical strength for sustained performance under typical tool load cycles.

Suitable for

• Repair and maintenance of Dedra DED7849 and compatible small electric motors
• Replacement during scheduled tool servicing to prevent excessive sparking
• Hobbyist and professional workflows that require restored commutation

Key specifications

• Material: electrographite (carbon)
• Function: motor brush for commutation and current transfer
• Application: small electric motors and power tools compatible with this brush design
• Typical benefits: reduced sparking, restored contact, improved running stability

How to use

Switch off and disconnect the power tool from the mains before beginning any work. Remove the motor housing or brush caps according to the tool manufacturer’s guidance to access the worn brushes. Extract the old brushes carefully, noting orientation and spring positioning, then insert the replacement brushes ensuring correct seating against the commutator and secure spring contact. Reassemble the housing and perform a brief no-load test to verify smooth commutation and absence of excessive sparking or noise.

Usage recommendations

Replace both brushes at the same time to ensure balanced wear and consistent electrical contact. Inspect the commutator surface for scoring or heavy deposits and clean or dress it if required. Follow safety instructions in the tool manual and use appropriate personal protective equipment when servicing electric motors.
