Your question: What are some of the main characteristics of a starter motor?

What is the main function of starter motor?

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 engine’s operation under its own power. Starters can be electric, pneumatic, or hydraulic.

What are the main components of a starter motor?

Starter Motor components & their functions:

  • Armature. The armature is an electromagnet, mounted on the drive shaft and bearings for support. …
  • Commutator. …
  • Brushes. …
  • Solenoid. …
  • Plunger. …
  • Lever Fork. …
  • Pinion. …
  • Field Coils.

What is the requirement of motor starter?

Motor starters consist of two devices—a contactor that completes the circuit to the motor and an overload relay that monitors the current the motor is drawing. This overload protection device is set to a pre-determined maximum load that the motor can safely handle.

Why starter is used in motor?

Starters are used to protect DC motors from damage that can be caused by very high current and torque during startup. They do this by providing external resistance to the motor, which is connected in series to the motor’s armature winding and restricts the current to an acceptable level.

Does a motor need a starter?

The need for a starter is dictated by the type of motor. Generally speaking, low-power motors do not require starters, although what’s considered low power may be debatable. For instance, small dc motors that run on low voltages (24 V or less) don’t require starters.

What is the function of motor starter with respect to current?

Explanation: The main function of the starter is to prevent excessive current flow. At the same time it should allow current to produce good or high starting torque.

What are the four major groups of component parts of a starter?

The starter converts electrical energy into mechanical energy to start the engine. Two major parts of a starter include an electromagnetic field and a rotating armature. Other significant parts of a starter include a solenoid, shift fork and the starter drive gear.

What are the types of starter motor?

Types of Magnetic Motor Starters

  • Direct-On-Line Starter. The direct-on-line starter is the simplest form of motor starter, other than a manual starter. …
  • Rotor Resistance Starter. …
  • Stator Resistance Starter. …
  • Auto Transformer Starter. …
  • Star Delta Starter.

Where is the starter motor?

Your starter can usually be found on the passenger’s side (if RWD) of the engine, just below the exhaust manifold. Or if it is FWD, check on the drivers side above the transmission or under the exhaust manifold. They can also be located just under the intake manifold on some vehicles.
