Characteristics of Deceleration Starter for Diesel Engines

Jan. 16, 2024

A starter with a gear reducer installed between the armature shaft and the drive gear of the starter is called a deceleration starter. So what are the characteristics of the deceleration starter of diesel engines?

The main difference between a deceleration starter and a conventional starter is that a gear reduction device is installed between the transmission mechanism and the armature shaft. Through the reduction device, the torque is transmitted to the one-way clutch, which can reduce the speed of the motor, increase the output torque, and reduce the volume and mass of the starter. The deceleration starter of diesel power generation has the following significant characteristics:

1. The power output structure is divided into two parts: the armature shaft and the transmission shaft. The two ends of the armature shaft are supported by ball bearings, with uniform load distribution, long service life, and less prone to wear; The armature is relatively short, making it less prone to bending the armature shaft and damaging the magnetic field winding.

2. Adopting a deceleration device. There is a reduction gear installed between the rotor and the starting gear, which increases the torque transmitted by the starter to the starting gear. By using an electromagnetic switch, the power output part of the motor (after passing through the reduction gear) is the starting gear and starting gear shaft, while the meshing part remains stationary.

Starters with low output power often use external meshing, while starters with high output power use internal meshing.

3. The deceleration starter is operated by an electromagnetic switch, and some are equipped with auxiliary switches (or sub switches). Its function is to prevent damage to the electromagnetic switch and starting switch. The graded connection of the electromagnetic switch to the power supply greatly reduces the possibility of damage to the starter, thereby extending the service life of the starter.

4. The volume and mass of a deceleration starter are about half that of a traditional starter, which not only saves raw materials but also makes disassembly and repair very convenient.

5. The magnetic pole number of a deceleration starter is the same as that of a traditional starter, but the magnetic field winding often uses the method of connecting multiple small wires in series. Although the winding method of the armature winding is the same as the traditional principle, the manufacturing process is advanced.
