The engine deceleration starter has the following salient features:
● The power output structure is divided into two parts: the armature shaft and the transmission shaft. Both ends of the armature shaft are supported by ball bearings, the load distribution is uniform, the use time is long, and it is not easy to wear. The armature is short, and it is not easy to bend the armature shaft and wear out the magnetic field winding.
● A reduction gear is adopted, and a reduction gear is installed between the rotor and the starting gear, and the torque transmitted by the starting motor to the starting gear will increase. Using the electromagnetic switch, the power output of the motor (after the reduction gear) is the starting gear and the starting gear shaft, and the mesher part does not move. The starter with low output power often adopts the external meshing method, and the starter with large output power adopts the internal meshing method.
● The deceleration starter is operated by electromagnetic switch, and some are equipped with auxiliary switch (or auxiliary switch). Its function is to prevent the electromagnetic switch and electric (starting) switch from being burned out. The power supply is switched on in stages, which greatly reduces the possibility of damage to the starter, thereby extending the service life of the starter.
● The volume and weight of the deceleration starter are about half of those of the traditional starter, which saves raw materials and is convenient for disassembly and repair.
● The number of magnetic pole pairs of the deceleration starter is the same as that of the traditional starter, but the magnetic field coil winding often adopts 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.
