Car starter motors are designed to deliver high torque for a short period of time; 30 seconds or less. They’re not intended for continuous use.
How long can a starter motor run?
On average, a starter motor lasts for 100,000-150,000 miles. In many cars, the starter motor lasts for the lifetime of the vehicle; however in some cars, it can fail prematurely.
What would cause a starter to continuously run?
So, if your starter keep running, the problem could be stuck starter relay contacts, a continuous ground on the starter relay control coil, or a binding ignition lock cylinder that keeps the actually ignition switch in the START position. … If the problem persists, it’s not a stuck relay.
Can you use a starter motor as a motor?
So, it may work, and you may be happy with the performance, but other types of motor may give you more range or speed. Starter motors are optimized for high torque and to survive the rough environment of a car. They are not designed for sustained use, and are not particularly efficient.
Can you bypass a starter?
You can easily use a screwdriver to bypass the starter relay. … The screwdriver is used to bypass a faulty ignition switch or starter relay. Use the screwdriver to connect both the solenoid terminal and the positive starter terminal.

How many rpm does a starter turn an engine?
Normal cranking speed for the engine is about 200 rpm. If the starter drive had a ratio of 18:1, the starter would be rotating at a speed of 3,600 rpm. If the engine started and was accelerated to 2,000 rpm, the starter speed would increase to 36,000 rpm.
How many watts is a starter motor?
Typically, a starter motor can consumer 100-200 amps of power at 12volts for 10-20 seconds.
How much power does a starter motor need?
A good starter will normally draw 60 to 150 amps with no load on it, and up to 250 amps under load (while cranking the engine). The no-load amp draw will vary depending on the type of starter. If the amp draw is too high, the starter needs to be replaced.
