Starter motor types

Star delta, auto transformer, stator resistance, rotor resistance starters to minimize starting current to motor. Find star-delta and soft starters details. In the case of very large engines, the starter can even be another internal-combustion engine. Internal-combustion engines are feedback . A starter turns an electric motor or motor controlled electrical equipment on or off, while providing overload protection.

It is an electrically operated switch which uses magnetic induction to provide startup current for a motor.

Direct On line: It consists of . Bosch starter motors are classified according to the type designation key shown in Figure 1. The first letter indicates whether the starter motor is a direct- drive model, a reductiongear model or a startermotor for commercial vehicles. Every motor needs a starter for its safe operation. Working of motorstarter and different types of motor starters and their techniques were explained clearly. Starter - motor type designations.

The main features of this type starter motor are its size and robust construction. For the engagement of the pinion to the flywheel ring gear, the complete armature assembly slides axially through the motor casing. A simplified construction of the starter is illustrated in Fig.

In the figure, the motor is shown in the rest . Need of using starters for Induction motor. Two (Star-Delta and Auto-transformer ) types of starters used for Squirrel cage. The clutch is available in the. Specifications and Performance depending on . The pinion is not fixed rigidly to the motor shaft - it is threaded on to it, like a freely turning nut on a very coarse-thread bolt.

An inertia- type starter motor is fitted with a Bendix gear on the shaft from the armature. When the started switch is turned on, the motor rotates rapidly, the shaft turns, and the Bendix gear screws the pinion along a thread until it engages with they flywheel ring gear on the engine. Power: inertia starter motors boast a better weight-torque ratio than other types of starter motor. They are lighter than other starter motors with a similar cranking torque capacity. Solenoid operated Delco MT series starter motor.

A common type of starter motor is the solenoid- operated direct drive unit. Although there are construction differences between applications, the operating principles are the .

Hydraulic motor starter assembly.

Keep in mind that the basic principles of operation will remain the same across each type of starter, but the parts and pieces employed to establish starter operation may vary between . On some starters, the solenoid also has a mechanical function. The solenoid activates a shift or engaging lever to slide the overrunning clutch along the shaft to mesh the pinion gear with the flywheel. When engage the starter motor then turns the engine, so meshing occurs before starting. About the starter motor types The .
