What is the difference between the DC motor and the AC motor of the electric pallet jack?

In recent years, with the continuous rise of labor costs and the improvement of operational efficiency requirements, more and more factories will use electric pallet trucks to replace the original manual pallet trucks. The power system of the pallet truck will use the drive motor. The drive motor of the electric pallet truck usually has a DC motor and an AC motor, so what is the difference between them?

The DC motor of the electric pallet truck uses direct current as the power source, while the AC motor of the pallet truck uses the alternating current as the power source. Structurally, the principle of the electric DC motor of the pallet truck is relatively simple, but the structure is more complicated, which is not conducive to the later maintenance of the electric pallet truck motor. Although the principle of the AC motor of the pallet truck is more complicated, the structure is relatively simple, so it is easier to maintain than the DC motor.

The DC motor of the electric pallet truck is to introduce the current into the rotor armature through the brush and the commutator, so that the rotor is rotated by the force in the stator magnetic field. The structure of the DC motor of the electric pallet truck should be composed of two parts: the stator and the rotor. The stationary part of the DC motor of the electric pallet truck is called the stator. The main function of the stator is to generate a magnetic field. The part that rotates when the motor of the electric pallet truck is running is called the rotor. Its main function is to generate electromagnetic torque and induced electromotive force. It is the hub for the energy conversion of the DC motor, so it is usually called the armature. , armature winding, commutator and fan, etc.

The AC motor of the electric pallet truck is to pass the alternating current into the stator winding to generate a rotating magnetic field in the stator and rotor air gap, and the rotating magnetic field generates an induced current in the rotor winding, Then, the rotor is forced to rotate in the stator magnetic field. AC motor: It is a machine used to realize the mutual conversion of mechanical energy and AC electrical energy. Due to the huge development of AC power systems, AC motors have become the most commonly used motors for electric pallet trucks. Compared with the DC motor, the AC motor has a simple structure, is easy to manufacture, and is relatively firm because there is no commutator. It is easy to make a motor with high speed, high voltage, high current and large capacity.

In practical applications, their specific differences are as follows:

Speed u200bu200bregulation: DC motor speed regulation is simple, but its use is limited. AC motor speed regulation is relatively complex, but it is widely used due to the use of AC power.

Noise: Because the DC motor of the electric pallet truck has brushes and commutators, the noise of the electric pallet truck is slightly louder when it is working.

Use and maintenance: The brushes and commutators of the DC motor of the electric pallet truck are relatively worn, so they need to be replaced frequently; the AC motor has no brushes and commutators, so maintenance is relatively convenient. In the long run, the maintenance cost of electric pallet trucks is also lower for AC motors, so AC motors are more and more used by electric pallet trucks.

are important in ensuring hand pallet truck manufacturers, and the machine is utilised by everyone from +pallet +truck +manufacturer to pallet jack manufacturers.
