What motor does a electric small forklift use?

In recent years, with the continuous increase of labor costs and the improvement of work efficiency requirements, more and more factories are using electric small forklifts to replace the original manual forklifts. The power system of electric small forklifts uses drive motors, and the drive motors of small electric forklifts usually have DC motors and AC motors. So what is the difference between them?

The DC motor of an electric small forklift uses DC electricity as the power source, while the AC motor of a forklift uses AC electricity as the power source. Structurally speaking, the principle of electric DC motors for forklifts is relatively simple, but the structure is more complex, which is not conducive to the later maintenance of mini electric forklift motors. Although the principle of the AC motor for forklifts is relatively complex, its structure is relatively simple, making it easier to maintain than DC motors.

Common types of electric forklift motors

The DC motor of an mini electric forklift introduces current into the rotor armature through brushes and commutators, causing the rotor to rotate under force in the stator magnetic field. The structure of the DC motor of an electric forklift should consist of two main parts: stator and rotor. The stationary part of the DC motor of an electric forklift during operation is called the stator. The main function of the stator is to generate a magnetic field, which is composed of the frame, main magnetic pole, commutator, end cover, bearings, and brush device.

The rotating part of the electric forklift’s motor during operation is called the rotor, which is mainly used to generate electromagnetic torque and induced electromotive force. It is the hub for energy conversion in DC motors, so it is usually called the armature, consisting of a shaft, armature core, armature winding, commutator, and fan.

The AC motor of an electric forklift passes AC electricity into the stator winding, generating a rotating magnetic field in the air gap between the stator and rotor. The rotating magnetic field induces current in the rotor winding, causing the rotor to rotate under force in the stator magnetic field. AC motor: a mechanical device used to convert mechanical energy into AC electrical energy. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motor for electric forklifts.

Compared with DC motors, AC motors have a simple structure, are easy to manufacture, are more sturdy, and can be easily made into motors with high speed, high voltage, high current, and large capacity due to the lack of a commutator.

In practical applications, their specific differences are as follows:

Speed regulation: DC motors have simple speed regulation, but their usage is limited. The speed regulation of AC motors is relatively complex, but it is widely used due to the use of AC power sources.
Noise: The DC motor of an electric forklift has brushes and commutators, so the noise during operation is slightly higher.
Usage and maintenance: The brushes and commutators of the DC motor of electric forklifts are severely worn, so they need to be replaced frequently; AC motors do not have brushes or commutators, making maintenance relatively convenient. In the long run, the maintenance cost of electric forklifts is also lower for AC motors, so AC motors are increasingly being used by electric forklifts.
