The inertia starter relies on the inertia of the pinion that is its reluctance to begin to turn. Inertia starter motors boast a better weight torque ratio than other types of starter motor.
Pre Engaged Starter Motors Ipu Group
Inertia starter motor diagram. Inertia system an inertia type starter. A starter also self starter cranking motor or starter motor is a device used to rotate crank an internal combustion engine so as to initiate the engines operation under its own power. They are lighter than other starter motors with a similar cranking torque capacity. The flywheel and movable gears of a combination hand electric inertia starter are shown in figure 1. No soft starter duration. Inertia starter motor the disadvantage of this starter pre engaged starter motors.
In the inertia starter energy is stored slowly during an energizing process by a manual hand crank or electrically with a small motor. 160kw electric motor direct start star delta. Lucas starter motors model m35g inboard type. Touch the negative lead to a bare metal part of the motor for a moment the voltage should drop but not more than half a volt lower than in the previous test. Inertia starters used a heavy wheel usually made of brass which was spun by a hand crank or electric motor causing the spinning wheel to engage the starter ring gear. If the car has an inertia type starter connect the positive lead to the feed terminal on the starter motor.
Starters can be electric pneumatic or hydraulicin the case of very large engines the starter can even be another internal combustion engine. Model m45g pre engaged type model m45g self index type the table below is intended to assist you in identifying which vehicles use which starter motors. This one is an inboard type in which the bendix gear throws the pinion towards the motor. Hand cranking the inertia starter on restored 1934 boeing p 26 peashooter fighter plane. This starter motor is the main clutcha clutch is a mechanical device that engages and. An aero engine inertia starter uses a pre rotated flywheel to transfer kinetic energy to the crankshaft normally through reduction gears and a clutch to prevent over torque conditions.
Three variations have been used hand driven electrically driven and a combination of both. Ipus inertia starters have been developed as an easy to install fit and forget system saving you costs on both installation and maintenance. Internal combustion engines are feedback systems which. If it was previously 11 volts it should remain above 105. There are also outboard ones in which it moves the other way.
