Types of Starter Motor
Below are the five types of starter and their difference:
Direct Drive Starter Motor DD
Direct drive the most common and older types of starter motor available out there. it comes with different applications and construction design but it’s solenoid operated unit. Well, its working remains plain like other types.
The solenoid is energized by the car battery when the ignition switch or key is pressed. This pushes the plunger to shift the lever that directs the pinion gear. The pinion gear which then meshes with the engine flywheel. So, as the starter motor spin, the flywheel spin along which then begin the engine combustion to run on its own.
Planetary Gear PLGR
The existence of these types of starter motor has vastly replaced the direct-drive types. It is a permanent magnet that transmits power between the pinion shaft and the armature. The armature spin with more speed and torque.
The essence of planetary gear is to reduce gear which further reduces the requirement of high current. There is a sun gear located at the end of the armature and three plenary carrier gears inside the ring gear held stationery.
Permanent Magnet Gear Reduction PMGR
The permanent magnet gear reduction is designed to offer less weight, easy construction and less heat generation. It features four to six magnet field assemblies rather than field coil starters. It has three terminals on the 12V solenoid, and also heavy-duty making to require less current. Because there are no field coils, the commutator and brushes transfer current directly to the armature.
Permanent Magnet Direct Drive PMDD
The PMDD types of starter motors are similar to the direct drive in several ways. Their difference is that the field coil is replaced with permanent magnets in the permanent magnet direct drive type.
