Description
What is the starter motor?
The starter motor is an electric motor that turns over the engine
to start. To turn the engine you need an electric motor that can
provide lots of torque for a brief period of time, on demand, over
and over again. But the engine needs to be started in the first
place, that is exactly what the starter motor is, plus a mechanism
to allow it to engage and disengage mechanically in an instant.
Function:
The primary function of a motor starter is to start and stop the
motor to which it is connected. These are specially designed
electromechanical switches similar to relays. The main difference
between a relay and a starter is that a starter contains overload
protection for the motor. So the purpose of the starter is two to
switch the power automatically or manually to a motor and at the
same time protect the motor from overload or faults.
How a Motor Starter Operates?
Basically, a starter is a switching device that consists of
electrical contacts (both incoming and outgoing). Based on the
operation, starters are primarily divided into hand operated and
electrically operated devices. Hand operated starter consists of a
lever on the side of it that can be turned on or off. Usually these
are used for smaller motors as they are incapable of operating
remotely. This type of motor starters causes the motors to restart
immediately after a power interruption. This instant operation of
the motor after power failure may leads to flow of dangerous
currents into the motor and hence the motor will be damaged. This
is the reason why most of the starters are equipped with electrical
switches.
How does the starter motor start the engine?
The starter solenoid powers the starter motor. At the same time,
the starter solenoid pushes the starter gear forward to mesh it
with the engine flywheel (flexplate in an automatic transmission).
The flywheel is attached to the engine crankshaft. The starter
motor spins, turning over the engine crankshaft allowing the engine
to start. In cars with a push button start, the system disengages
the starter as soon as the engine starts running.
