What is the difference between DC and AC motor for electric pallet stacker truck？

In recent years, as labor costs continue to increase and operational efficiency requirements increase, more and more factories will use electric pallet stacker truck instead of the original manual pallet jack stacker. The electric pallet stacker truck will use the drive motor. The drive motor usually has a DC motor and an AC motor. What is the difference?

As the name implies, the DC motor of the electric pallet jack stacker uses a DC power source as the power source, and the AC motor of the electric pallet stacker truck uses the AC power source as the power source. Structurally speaking, the principle of the electric motor of the electric pallet jack stacker is relatively simple, but the structure is relatively complicated, which is not conducive to the later maintenance of the motor of the electric pallet stacker truck. Although the AC motor of the electric pallet jack stacker is more complicated, the structure is relatively simple and therefore easier to maintain than the DC motor of the electric pallet stacker truck.

The DC motor of the electric pallet jack stacker introduces current into the rotor armature through brushes and commutators, thereby forcing the rotor to rotate in the stator magnetic field. The structure of the DC motor of an electric pallet stacker truck should consist of two parts: the stator and the rotor. The portion of the electric pallet jack stacker that is stationary when the DC motor is running is called the stator. The main function of the stator is to generate a magnetic field consisting of a base, a main pole, a commutating pole, an end cap, a bearing and a brush device. The portion of the electric pallet stacker truck that rotates while the motor is running is called the rotor. Its main function is to generate electromagnetic torque and induced electromotive force. It is the pivot for the energy conversion of electric pallet jack stacker motors and is therefore often referred to as the armature. , armature intimate, armature windings, commutators and fans.

The electric motor of the electric pallet stacker truck delivers alternating current into the stator windings, creating a rotating magnetic field in the stator air gap that produces an induced current in the rotor windings, causing the rotor to rotate downward. Stator magnetic field. AC motor: A machine used to convert mechanical energy and alternating current. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors for electric pallet jack stacker. Compared with DC motors, AC motors of electric pallet stacker truck are simple in structure, easy to manufacture, and relatively rugged. It is easy to manufacture high speed, high voltage, high current, and large capacity motors.

In practical applications, their specific differences are as follows:

Speed regulation: The DC motor of the electric pallet jack stacker is easy to adjust, but its use is limited. The AC motor speed adjustment of the electric pallet stacker truck is relatively complicated, but is widely used due to the use of AC power.

Noise: The DC motor of an electric pallet jack stacker is slightly noisy when using brushes and commutators.

Maintenance: The brush and commutator of the DC motor of the electric pallet stacker truck are seriously worn and need to be replaced frequently; the AC motor of the electric pallet jack stacker has no brushes and commutators, and the maintenance is relatively convenient. The long-term maintenance cost of the electric pallet stacker truck is also lower than the cost of the AC motor, so the electric pallet jack stacker uses more and more AC motors.
