Automotive Starter Motor and Alternator Market Projected to Gain Significant Value through 2021-2031

An automotive starter is used to turn on the internal combustion engine. The starter motor needs a considerable amount of current to start the engine. When the engine is cranked, the heavy draw of the starter motor temporarily pulls down the battery voltage. The starter motor uses electricity to crank the engine in order to start it. There are three types of automotive starters: electric, pneumatic, and hydraulic. An alternator is used to charge the battery and power the electrical systems in automobiles. It is a part of the car charging system that powers the engine. It consists of three main mechanisms: a voltage regulator, an alternator, and a battery. The alternator works with a battery to produce power for electrical parts of a vehicle, such as an instrument panel and exterior & interior lights. The alternator generates AC power with the help of an electromagnetism mechanism, which is produced through the position of the rotor and the starter.

The reduction in the size of engines has prompted manufacturers to develop starter motors and alternators that are in line with future trends. Different technologies, such as the belt-driven alternator, enhanced starter, integrated starter generators (ISG), and direct start have been introduced. These technologies are utilized in micro-hybrid and hybrid vehicles. The promotion of greener vehicles also boosts the demand for automotive starters and alternators around the world. The global automotive starter motor and alternator market is projected to advance at a decent growth rate throughout the assessment tenure, owing to an increase in the production of vehicles.

Demand for Fuel-efficient Vehicles to Drive Adoption of Automotive Starter Motors

An increase in automotive production across the globe is estimated to fuel the global automotive starter motor and alternator market. Moreover, an increase in sales of two-wheelers as well as cars is likely to provide significant opportunities for the automotive starter motor and alternator market during the forecast period. A rise in urbanization and disposable income of people drives the automotive industry, which is further expected to boost the market.

For instance, Valeo SA introduced a hybrid4all system for automobiles. It combines a low-powered engine with a conventional combustion engine, reducing fuel consumption by up to 15%, cutting up the carbon dioxide cost per gram as compared to that of a hybrid in the market.

India and other developed and developing economies are expected to spend more on automobiles, due to advanced technologies, investment in research and development by manufacturers, and the creation of innovative automotive parts, which in turn is anticipated to further drive the automotive starter motor and alternator market across the globe. As such, automotive starter motors and alternators are being extensively used for both petrol and diesel engines.

The increasing adoption of electric vehicles (EV) due to environmental concerns, such as rising air pollution, is projected to boost the demand for automotive starter motors and alternators during the forecast period. Increasing preference for lightweight and fuel-efficient vehicles is also expected to fuel the demand for automotive starter motors and alternators across the globe.

Gear-reduction Technology Starter Motors Enhance Battery Life, Offer Other Advantages

Gear-reduction (GRS) technology is fast replacing direct drive technology starter motors across various segments. Gear-reduction (GRS) technology starter motors offer more advantages than direct-drive starter motors such as the lighter-in-weight feature and compactness. The GRS technology requires less space on any vehicle and enables high specific torque and its speed starts the engine at a faster rate. Furthermore, GRS starter motors enhance battery life as less current is drawn by the starter motor. These motors are easy to service and require low maintenance costs. All these factors are likely to propel the demand for automotive starter motors and alternators.

On the other hand, numerous manufacturers have developed alternators based on the current conventional designs with an external fan. These are classical and ventilated versions that are used in various segments such as tractors, farming equipment, and stationary engines. These alternators are built with utmost care to ensure the stability of output for continuous charging to the battery while operating under different working environments and applications. Also, the servo motor helps to support precise control of angular or linear position, velocity, and acceleration in different vehicles. Apart from these motors, manufacturers are increasing R&D to innovate in self starter motors.

Combining Integrated Starter Generator and ICE to Create Lucrative Opportunities

In terms of technology, the global automotive starter motor and alternator market has been classified into belt-driven alternator starter (BAS), direct start, integrated starter generator (ISG), enhanced starter, and others. The integrated starter generator (ISG) segment held a significant share of 39.55% of the market in 2021. The segment is projected to maintain its position in the market and grow at a CAGR of 4.67% during the forecast period. These technologies help support the optimum performance of the automotive motor.

The integrated starter generator (ISG) is just one of the solutions in the EV development timeline. Combining the integrated starter generator (ISG) with the ICE creates a mild hybrid electric vehicle (MHEV), and this hybrid power solution offers new opportunities for electronic modules and electric motors. The integrated starter generator (ISG) unit replaces the starter and alternator functional modules while augmenting the ICE functionality. In this assembly, there are two batteries, one traditional 12V battery, and another 48V lithium-ion battery. Such innovations are boosting the demand for robust vehicle starter motors.

The 48V lithium-ion battery supplies higher power loads, such as the inverter that powers the electric motor of the BSG/ISG. The 12V battery remains on MHEVs to power legacy electronic control modules in the vehicle and provides alternate low voltage electronics power to 48V systems if needed. The MHEV provides automotive original equipment manufacturers (OEMs) an intermediate step between traditional combustion engine propulsion and fully electric propulsion that is found in battery electric vehicles (BEVs).
