Objective : To obtain centre of competence for regulators, improving existing quality levels to meet international customer requirements.
Project : Regulator export (100%)
Product : Regulators – various types (BR, MR, MFR etc.)
Used in : LIC type (Compact) alternators
Application : Regulators are used in alternators, used for Light Commercial Vehicles
(LCV) and Heavy Commercial Vehicles (HCV) in Europe and other countries excluding India
Customers and Market
The Regulators are exported to Robert Bosch plants in Cardiff (UK), Goettingen (Germany), South Africa, Treto (Spain), and aftermarket in Karlfshrue in Germany. These are used in LIC type (compact alternators) which are produced by these plants.
Infact, demand for Compact Alternators is raising each day. In India, some of the new generation car manufacturers are trying out compact alternators.
Product Profile
The regulator is one of the sub-assemblies used in the Compact alternator, which becomes the onboard "Electricity Generating Plant" when an engine runs in a motor vehicle. The regulator’s purpose is to limit the alternator voltage to the maximum value across the whole of the engine speed range, irrespective of load and rotational speed. The alternator's task is to supply power to all of the vehicle's current consuming loads and systems.
The regulators are of the electronic version and are used solely with alternators. Due to their compactness, low weight and insensitivity to vibration and shock, they can be directly integrated with the alternators.
A regulator consists of electronic chip in which the Integrated Circuit (IC), power stage and free-wheeling diode have been incorporated and a Brush holder which is used for mounting in the Alternator. The Brush holder also houses the Carbon brushes actuated by springs and electrical contact between the Brush holder and the chip is established through Bus bars.
Material and Inputs
The raw-material and components are by and large imported from various suppliers in Germany, Spain and UK. The major inputs that are imported are brush holders, electronic chips, electronic assembly, carbon brushes, springs, etc. Localisation opportunities are being explored and will be implemented wherever found feasible.
