How about the small small electric forklift with DC motor?

The motor is very important for small electric forklift. Drivers and enterprises preparing to purchase small electric forklifts should carefully understand it. As we said before, the motor of small electric forklift has both DC and AC, and AC has more advantages than DC, and its application is more and more extensive. However, there are still many DC motor small electric forklifts on the market, proving that it has its own irreplaceable advantages. Now, electric forklift manufacturer will introduce the DC motor to you.

First, let's talk about the composition of the DC motor of the small electric forklift. The DC motor is composed of magnetic field, armature, brush and brush holder. The magnetic field is composed of magnetic field iron core, magnetic field winding and motor shell. DC motor has two stages (one pair of magnetic poles), four stages (two pairs of magnetic poles), six stages (three pairs of magnetic poles), etc. Armature is composed of armature winding, armature core, commutator and armature shaft, which is used to bear force in magnetic field and generate electromagnetic torque after being energized. The main function of the brush is to cooperate with the commutator of the armature to realize the current commutation of the armature winding and change the direct current of the battery into the alternating current inside the armature. Electric forklift manufacturer tells you that the above is the composition of DC motor.

Let's talk about the classification of DC motors for small electric forklifts. According to different functions, it can be divided into traction motor, lifting motor and steering motor. Their working principles are basically the same, but the power size and excitation mode are different. According to different connection relationship between magnetic field and armature winding, it can be divided into separately excited, series excited, shunt excited and compound excited. Electric forklift manufacturer tells us that their specific differences are complex, and interested friends can consult in detail.

The DC motor of small electric forklift has some advantages, such as low price, large traction, simple speed control, high speed with light load, low speed with heavy load, and strong starting and overload capacity. However, the armature current is leaded by the brush and the commutator, there is an electric spark when reversing, which is easy to cause commutator ablation. Not only that, it also has such fatal weaknesses as easy wear of brushes, loud noise, short service life, etc. Electric forklift manufacturer suggests that enterprises should fully consider the budget and demand before deciding whether to use DC motor small electric forklift or AC motor small electric forklift.
