Auxiliary - Fuel pump brush
Designing a fuel pump application is a challenge because corrosive fuel interacts with the commutating parts of the engine: brush , disc and ring. AVOCarbon uses specific resin grades to create brushes that can operate in any fuel environment. The range of products extends from fuel-pumps using copper commutators to graphite commutators.
Comfort: window lift, seat mover, sun-roof
Metal graphite grades designed by AVOCarbon give great performances under varying temperatures, dampness constraints, and current conditions for Intermittent duty applications. Using adaptable manufacturing processes on any of the three molding directions, AVOCarbon can adjust to a wide range of technical requests.
Auxiliary – Blower, engine cooling fan and HVAC
AVOCarbon metal graphite grades meet most of the acoustic noise requests found in auxiliary small motors. Brushes featuring these grades have a longer lifespan and stable performances over time plus low acoustic and low electromagnetic noise, both for 12V and 24V applications.
Powertrain - Electric Vehicles (EV)
AVOCarbon has built specific grades suited for Electric Battery Vehicles. EV grades are used on brushes qualified for applications ranging from electric golf carts to OEM electric cars. Grades allow constant performances and reliable lifespans, under any operating circumstances.
Powertrain - Starter & alternator
Using 12V and 24 V metal graphite grades either in single or dual layer configurations, AVOCarbon brushes cover power ranges from 1 to 6 kW for starter motors. Metal graphite grades are tailored for long lifespans and performances for conventional starter applications and demand start/stop starter applications.
Benefits from assemblies
AVOCarbon provides an optimal integration of the brush on its holder to achieve the best performances. Integrated brushes allow better control over assembly functions which are crucial for optimal brush operations like forcing the brush against the collector or a sliding gap between the brush box and the brush. For customers, integration of brushes simplifies manufacturing processes by handling sub-assemblies.
Types of assemblies
AVOCarbon can deliver brushes with custom finishing operations like braid welding or specific packaging. AVOCarbon can integrate its brushes into simple or more elaborated assembly including terminals, springs, sleeves, electronic circuitry, EMI protection or thermal control of powered motors.
Bakelite plate with crimped or printed circuit
For medium sized motors in high temperature environments, bakelite plates are a good choice. AVOCarbon has experiences in integrating bakelite plates and metal brush boxes for application, such as front wipers and small EC motors. AVOCarbon can also integrate the design and manufacturing of bakelite plates.
Plastic holder with crimped circuit
Plastic holders with a crimped circuit fit low to medium power motors such as rear wipers, sun roofs or seat movers. AVOCarbon has a long experience and expertise in designing and manufacturing plastic holders with crimped electric tracks for high volume applications.
Inductors (or chokes) for motors
Passive inductor components are found on most brush holders. Chokes provide for a better flow of current to the collector and are used for EMI protection of the motors. AVOCarbon has deployed manufacturing capacities for these components to improve the design and to conform with cost requirements and is able to integrate them on its brush holders’ assemblies process.
As an addition to stand-alone brush holders, AVOCarbon can design and manufacture various harnesses ranging from simple to complex ones, draining power current or control command to motors. AVOCarbon has the knowledge to manufactures harnesses and connect them with automotive systems.
Electric engines are everywhere, for domestic or professional use.
