Starter motors are needed to start an engine, usually automotive engines. This is done by means of converting electricity into mechanical energy which is then utilized by gears to set the engine into motion. Once an engine starts rotating, it begins generating its own power and the starter motor then disengages. Complex in their assembly, starter motors are as much susceptible to problems as other vehicle parts and if poorly built, they may need attention in terms of regular maintenance.
Engines are feedback systems which once started, rely on the motion from each nth cycle to initiate the next cycle. In a four-stroke engine, the third stroke releases energy from the fuel, powering the fourth (exhaust) stroke and also the first two strokes of the next cycle, as well as powering the engine’s external load. To get this feedback started, the first two strokes must be powered in some other way. The Delcostater motor is used for this purpose, then is not needed once the feedback system is running.
A starter motor is a device that is used to start an engine before its operation allows it to generate power for itself. These motors are a vital component within automotive engines where they induce rotation in the engine so that the automobile can move. These motors taken in electrical energy and convert it into mechanical energy which is used by the rotor to turn and start the engine. A motor disengages once the engine starts generating power for itself, or is up and running. They provide the initial power surge to the engine so that it starts generating power for its operation. Like with most automotive parts, it is important that such motors should also be of good quality and make.
The Need for Starter Motors
Starter motors evolved from the hand-driven crank or hand crank of old times. Visuals of black and white pictures with gentlemen stepping out to crank up a car through a hand-held shaft in the front of its bonnet are examples of manually starting motors. However, manual starting of motors was not a risk-free enterprise and if the crank backfired, it resulted in serious injuries such as fractured fingers or wrists of the person operating it.
However, the problem that arose in the initial years was also one of how to develop an electric starting system or a power generating device that could deliver enough power to kick start a machine out of inertia and into motion. Modern starter motors were born out of this challenge.
The Modern Starter Motor
Modern day starter motors are direct current electric motors with a starter solenoid that draw current from a battery. Once current is drawn, this solenoid helps engage the gears that finally make the engine rotate and begin operating. The solenoid plays another important role; it helps pull away the pinion gear attached to the motor assembly. This disengages the motor from the engine flywheel and helps bring it to a stop.
Our patented internal magnetic solenoid switch enhances starter reliability. It is a one-wire design integrated inside the solenoid. Input current can be controlled by the ECM to protect from voltage spikes. Because of its integration inside the solenoid, it is protected from corrosion caused by environmental factors and damage from vibration issues.
