How fast does a starter turn an engine

A starter drive includes a pinion gear set that meshes with the flywheel ring gear on the engine's crankshaft. To prevent damage to the pinion gear or the ring gear, the pinion gear must mesh with the ring gear before the starter motor rotates. To help assure smooth engagement, the end of the pinion gear is tapered. Also, the action of the armature must always be from the motor to the engine.

The engine must not be allowed to spin the armature. The ratio of the number of teeth on the ring gear and the starter drive pinion gear is usually between and These motors work under heavy load. They produce big power in a short time and in a small volume. Starter motor conveys its rotating energy with a pinion to the flywheel. Your starter is really an electric motor. When you turn the ignition switch, the starter motor is energized, and the electromagnet inside the body engages.

This pushes out a rod to which the pinion gear is attached. Shock » Feb 10 pm. Skip to content. Quick links. Car starter motor Get all your technical information about electric bikes here. Car starter motor Post by babydark » Feb 10 am What do you think about using a car starter motor on a bike?

With the gas engine, I was able to go up to 53 mph but now I want to convert it to electric power. I have a Bosch starter motor form a jetta diesel with permanent magnets and internal gear reduction. This motor turn around rpm at 12v and draw something like 40 amps at no-load. On my bike the motor won't be able to turn faster than - rpm and will be controlled with a homebuild pwm controller. I have some doubts about the efficiency of this motor on my setup. Re: Car starter motor Post by lawsonuw » Feb 10 am babydark wrote: and draw something like 40 amps at no-load.

The first contact supplies a low current to the motor so that it turns slowly - just far enough to let the pinion teeth engage.

Then the second contacts close, feeding the motor a high current to turn the engine. The Video Course teaches you everything about modern cars.
