This article will introduce the selection and calculation method of the motor of the power roller conveyor, including the calculation formula of motor power for roller conveyors and roller conveyors speed and the matters needing attention in motor selection. Taking a food processing plant as an example, the appropriate motor is selected through calculation to ensure the stable operation of the automated conveyor systems and reduce energy consumption. Finally, it is emphasized that motor selection is an important part of conveyor design and needs to be adjusted and optimized according to specific circumstances.

1. Motor power calculation for roller conveyors

The motor power of conveyor machine is an important parameter of the powered roller conveyors. Its calculation method is determined based on factors such as the length of the roller conveyor systems, material weight, belt speed and transmission efficiency. The specific formula is as follows:

P = (L × m × g × v × η) / 367

P is the motor power (unit: kilowatt)

L is the conveyor line length (unit: meter)

m is the material weight (unit: kilogram)

g is the acceleration of gravity (unit: meter/second²)

v is the belt speed (unit: meter/second)

η is the transmission efficiency

2. Motor speed calculation for roller conveyors

The motor speed of heavy duty roller conveyor also needs to be calculated based on the actual situation of the conveyor machine. Generally speaking, the higher the conveyers belt speed, the higher the required motor speed. The motor speed calculation formula is as follows:

n = v / π × d

n is the motor speed (unit: revolutions per minute)

v is the belt speed (unit: meters per second)

d is the roller diameter (unit: meters)

3. Calculation Example

Take a food processing plant as an example. The plant needs motorized conveyor with a length of 50 meters, a belt speed of 1 meter per second, and a material weight of 20 kilograms per meter. Based on these parameters, we can perform motor selection calculations.

According to formula 1, we can calculate the motor power of conveyors as: P = (50 × 20 × 9.8 × 1 × 0.9) / 367 = 24 kilowatts.
According to formula 2, we can calculate the motor speed of conveyors as: n = 1 / (3.14 × 0.2) = 16 rpm.

Combining the above calculation results and precautions, we can choose a motor with a power of 25 kilowatts and a speed of 16 rpm to ensure the stable operation of the roller conveyor systems and reduce energy consumption.

In summary, motor selection calculation is an important part of the design of power roller conveyors. Through reasonable calculation and selection of suitable motors, the stable operation of the converor can be ensured, production efficiency can be improved, and energy consumption and operating costs can be reduced. In practical applications, corresponding adjustments and optimizations need to be made according to the specific situation to meet the needs of different production scenarios.

4. Consider backup power
It is usually recommended to leave a 10%-20% margin on the calculated power to ensure that the conveyor can still operate normally when the load fluctuates.
