Question: How powerful is a starter motor?

I understand that most car starter motors’ power is rated between 0.5kw to 1.5kw.

How much power does a starter motor use?

Typically, a starter motor can consumer 100-200 amps of power at 12volts for 10-20 seconds. Because there is such a variation, it is hard to give an exact figure. Then is the continual running of the car engine, and the electronics for the ECU and the spark system.

How many HP is a starter motor?

A starter for a normal car is between 0.8 and 1.2 HP.

Can you use a starter motor as a motor?

Starter motors are designed to be most efficient at starting engines : getting a large mass moving to a particular speed – but not for extended long period running. … So, it may work, and you may be happy with the performance, but other types of motor may give you more range or speed.

How long can you run a starter motor?

A starter motor should never be operated at no load or at full load for more than a few seconds, perhaps up to a minute. They are designed to operate in a fault mode just long enough to start the engine. Even at a moderate load, they do not have sufficient cooling for continuous use.

What is the current draw of a starter motor?

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.

Can a starter draw too much power?

Yes, the starter can go bad and draw too much power and not turn fast enough.

How much voltage does a starter need?

Working the starter switch should cause a drop from 12 volts to below 0.5 volts. If the voltmeter reading stays above 0.5 volts, look for a bad connection at the battery earth strap (at either end) or the engine-to-body earth strap.

How many rpm does a starter turn an 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 15:1 and 20:1. This means the starter motor is rotating 15 to 20 times faster than the engine. Normal cranking speed for the engine is about 200 rpm.

Can you control the speed of a starter motor?

The purpose of starter of a DC motor is to limit starting current taken by armature . This is done by having resistance in the armature circuit and as machine picks speed this resistance is progressively cut to zero. The starter is not intended to control speed.

What kind of motor is a starter motor?

The starter motor is an electric motor that turns over or “cranks” the engine to start. It consists of a powerful DC (Direct Current) electric motor and the starter solenoid that is attached to the motor (see the picture).
