Choosing Between Single and 3-Phase Motor for Conveyors


Single Phase and 3 Phase Motor Selection Factors for Conveyors
The power source factor is often a user consideration for choosing a conveyor motor. Most power sources in Indonesia use a single-phase. Based on these conditions, industry in Indonesia prefers single-phase to 3-phase only to adjust the existing power source.
Many conveyor users still do not fully understand what factors must be considered in choosing a conveyor driving motor. The factors discussed in this article are vital to consider so that the proper motor for the conveyor is selected and can increase the productivity of your industry.

Single Phase and 3 Phase Motors for Conveyors

Most likely you already know about single and 3-phase motors. Therefore, we will only discuss it a little bit as a reminder of your knowledge about the choice of this conveyor driving motor.

Single-Phase Conveyor Motor

Conveyors that use single-phase motors are suitable for product transfer processes with light loads. The single-phase uses one electrified cable and a neutral cable in the power distribution process.
Single-phase motors require additional circuitry because their power supply connected to the alternating current (AC) motor does not produce a rotating magnetic field. The supply voltage of the single-phase motor goes up and down or in other words, the power output of the single-phase supply is not constant.

3-Phase Conveyor Motor

The 3-phase motor conveyor is more suitable for product transfer in the industry. Because the 3 phase motor is released greater power than a conveyor with a single-phase motor.
The power output of this 3-phase comes from one neutral wire and three-conductor wires. The electric voltage that comes out of the 3-phase motor reaches 415v. It makes the driving force of the conveyor with a 3-phase greater than the single-phase which is only up to 230v.
However, from the two explanations above, we must understand when to use a single-phase single-phase and when to use 3-phase for motor conveyors. Here is a summary of 3 main factors in choosing the proper conveyor motor for your industrial production line.

Product Weight

We have discussed the weight of the conveyor in the selection of conveyor belts. We will continue to discuss product weight as a major factor in choosing a conveyor motor in this article.
"The heavier the product, the greater the energy required. It also applies to the total weight of the product on the conveyor. The greater total weight of the product, the more powerful a conveyor motor is needed for the transfer process"
For medium-light duty, you can use a conveyor with a single-phase motor. Then you can use a 3-phase motor conveyor for medium-heavy duty needs. However, it is possible to use a 3-phase motor conveyor for medium-light duty. On the other hand, it is not recommended to use single-phase for medium-heavy duty needs.

Conveyor Dimension

This point is towards the length of the conveyor. The length of a conveyor depends on the needs of its use. The longer the required conveyor, the longer the conveyor belt is used.
"Long conveyor belts require great power to move them, so a 3-phase motor will suit these conditions. However, it is possible to use a single-phase motor with a long conveyor belt. The difference will be seen in the speed of the conveyor itself"
The thickness of the conveyor belt can also be a consideration in determining the conveyor motor. This consideration is not as significant as the length of the conveyor belt, but you need to discuss this further with the team or with a professional to determine the proper conveyor motor.

Power Source

The power source is the main reason for users to choose conveyor motors. Generally, the socket in Indonesia is for single-phase. So that many conveyor users tend to adjust to the power source they have compared to considering the previous two points.
However, this condition is unavoidable because the sockets in Indonesia are generally single-phase. We can fulfill large power requirements with single-phase socket conditions by installing an inverter on the plug.

Choosing a Conveyor Motor

Choosing a conveyor motor between single-phase or 3-phase is about the needs and practicality of your industrial production line. It is not only on one factor but also considers other factors in choosing a conveyor motor. Because there is an investment value in the conveyor motor that you choose.
There are at least three factors that you must consider in choosing a conveyor motor, including product weight, conveyor dimensions, and also the power source. Identify your needs by considering these three factors to choose the proper conveyor motor for your industry.
