RECTIFICATION IN SITU OF COMMUTATORS OR SLIP RINGS

Use of CARBONE LORRAINE technology allows reduction of global cost of the total repair. This provides the optimum conditions for good carbon brush operation and removes the constraints of time and risk that would be created by the removal of the motor.

Hereafter the various stages of rectification :

Control of the vibration and isolation of the motor.
Feasibility study for the rectification of the commutator or slip rings.
Choice of the grinding system.
Method of fixing the grinding system.
Method of driving the machine (without or with power).
Safety.
Rectification according to CARBONE LORRAINE recommendations for good carbon brush operation
Undercutting the micas.
Chamfering commutator bars.
Control of final dimensions (roughness, profile on track, profile off track).

With this patented technology conducted by our technicians, we provide rapid rectification and undercutting of the micas. At the same time, eliminating pollution caused by copper, carbon and other dust.

Specific design of the grinding system for compact traction motors.
Driving the motor by using auxiliary power supply.
Rectification using diamond tool with dust extraction.
Chamfering commutator bars and undercutting micas in one pass.

MOUNTING AND ADJUSTMENT OF THE BRUSH-HOLDER

When we are on site, we can also ensure the correct mounting and adjustment of the brush-holders on your electrical machines.

The Maintenance Service works on all types of electrical machines equipped with carbon brushes:

Alternators.
Generators.
Industrial DC motors.
Slip rings motors.
